ApplicationDO I NEED A COUNTERBALANCE VALVE?A counterbalance is generally used for one or more ofthe following purposes:Control an Overrunning Load It restricts the flowfrom an actuator, thus forcing the load to be pushedthrough the restriction and providing control of thepotential runaway load. This also helps in the preven-tion of cavitation.Control in Critical Metering Applications Theoutward restriction also helps to gain control of sys-tems with varying loads and speeds.Holding a Load Much like a pilot operated checkvalve, a load is held in one direction until the appropri-ate pilot pressure is available unseat the check andpass fluid.

IntroductionCounterbalance valves are one of the most misunderstood products in the hydraulic industry. Many people tend tocomplicate the task of selecting a counterbalance valve and as such avoid opportunities. The goal of this TechnicalTips Section is to hopefully eliminate some of this confusion and help you chose the correct valve for your applica-tion. It is only a guide! It is not meant to be your only method of input, nor is it meant to replace good hydrauliccommon sense and reasoning.

NOTE: Counterbalance Valves are only needed if the appli-cation calls for varying loads or varying speeds. If the loadand speed are fixed, flow control valves and pilot operatedcheck valves may be substituted at generally a lower cost.

OperationAn understanding of the general operation of a coun-terbalance valve is required before proceeding furtherinto valve selection.The counterbalance valve is a pressure control deviceand functions as follows: Pressure is developed at theWork Port of the holding valve when the actuator ispressurized. This pressure acts on the differential area,and the force generated is counteracted by the biasspring. When there is sufficient pressure present toovercome the spring setting, the poppet begins to shift,allowing fluid to pass through the valve port to tank viathe control valve.To assist in the shifting of the poppet, an externalpressure source (generally the opposite side of theactuator) is connected to the pilot port of the counter-balance valve. This pressure is applied to the pilot areaand assists the differential area in opening the valve.The pilot assist reduces load pressure required toopen the valve, and allows for a reduction in thehorsepower required to move the load. If the loadattempts to run away (move faster than the pump cansupply flow), the pilot signal will diminish and thepiston will begin to close restricting flow to tank andthus controlling the load. The counterbalance pistonwill maintain a position that maintains a positive pilotsignal and will control the descent of the load.

Help Protect Against Hose Failures Since thefluid must be pushed through arestriction, hose failures resultin a controlled movement ofthe actuator and nota runaway load.

An added feature of the counterbalance valve is itsbuilt-in thermal relief characteristic. A temperature risecan cause thermal expansion of the hydraulic fluidtrapped between the actuator and the counterbalancevalves poppet. As the pressure increases and reachesthe bias spring setting, the poppet unseats and a fewdrops of oil are allowed to escape through the valveport of the counterbalance valve. This relieves thethermal expansion of oil, allowing the counterbalancevalve to continue holding the load in the same position.When the flow is reversed to the actuator, then pres-sure unseats the built-in bypass check portion of thecounterbalance valve allowing flow to pass from thevalve port to the work port. When no pressure isapplied to either port of the counterbalance valve, theload is held in place.

Valve SeriesParker offers the four series of products outlined below:MHC The MHC series is a threaded cartridge stylecounterbalance valve. This series is ideal for incorpo-rating into an integrated manifold or for installationdirectly into the port of the actuator. There are variousflow rates and pilot ratios available for the MHC Series.CB101 The CB101 is also a threaded cartridge stylecounterbalance valve. It also is ideal for incorporatinginto an integrated manifold or for installation directlyinto the port of the actuator. The CB101 has anindustry common cavity (C10-3) and is available inthree pilot ratios.E2 Series The E2 Series valves are threadedcartridge style counterbalance valves. They areavailable in standard and Vented configurations. In theVented configurations, the valves maintain theirsettings regardless of system backpressure. There arevarious flow rates and pilot ratios available.

MHC-010

CB101

Selecting OptionsBelow is a brief description of the options available onthe ordering information pages and a brief explanationof when each would be used.Flow Selection Generally the counterbalance valveis sized according to the actual flow the valve will seeand not the system flow. Note that the ordering infor-mation callout is the nominal flow rate and not themaximum. In other words, refer to the pressure dropcurves when sizing the valves. For example: A MHC-010 can flow 25 GPM, but is rated as a 10 GPM valve.It is possible to oversize a counterbalance valve! If thecounterbalance is oversized, the annulus between thepoppet and the seat is too large, thus the poppetopens too far causing instability. Remember you aregaining control by causing a restriction. If you oversizethe counterbalance valve, the restriction is reducedand so is the control.Vented versus Non-Vented With a standard coun-terbalance valve, the bias spring is internally vented totank. This means any pressure on the tank line issensed in the bias spring chamber and additive to thesetting. Thus, the pressure at the work port now must

be greater than the bias spring plus the tank pressurebefore the counterbalance poppet will shift allowing flow.A vented style counterbalance valve relieves the biasspring chamber to atmosphere. Thus, the springchamber is in no way related to the tank chamber ofthe counterbalance valve. So, if the pressure on the tankline is high, or if the pressure setting is critical, then avented style counterbalance valve would be required.Parkers counterbalance valves are externally vented.This means no extra porting or manifold costs areincurred when a vented counterbalance is needed.MHC-010-S*S* Non-Vented Counterbalance Adjustable

Selection Options (Continued)Pilot Ratio The pilot ratio is the ratio of the pilot areaversus the differential area poppet. Thus, the higherthe pilot ratio, the less pressure that is needed toassist the load pressure in unseating the poppet. Thismeans there is less restriction to the overrunning load,resulting in less horsepower required and more controlof the load. So higher pilot ratio equates to lessrestriction to the overrunning load, less control andless horsepower required. Lower ratio equates to morerestriction to the overrunning load, more control andmore horse-power required.The pilot ratiodecision is oneof Horsepowerversus Control. Forreference the mostpopular ratio is 6:1.

ADJUSTMENT TYPEParker offers counterbalance valves with adjustableand non-adjustable pressure settings. The non-adjustable or shimmed version is recommended formost applications as it prevents tampering or improperadjustment by uneducated end users.SELECTING SETTINGSThere are three basic settings to consider beforefinalizing a counterbalance valve for your application.Holding Setting The holding setting is sometimesreferred to as the counterbalance setting. It is themaximum load setting you expect the counterbalanceto hold. Note that the counterbalance valve should beset for the absolute maximum hold pressure required.Also note that counterbalance valves are restrictivetype devices and as such are not ideal for low pres-sure applications, such as those below 750 psi. Theholding setting is the setting you choose when select-ing a counterbalance valve.

PP = (TS L) / RPPP = Pilot PressureTS = Thermal SettingL = Induced LoadRP = Pilot Ratio

Example:The maximum load is 3000 psi. A 6:1 Pilot Ratio waschosen and the thermal relief setting is the standard1000 psi over load setting. What is the pilot pressurerequired to retract the cylinder if it is fully loaded? Whatpilot pressure is required to retract the cylinder if thereis no load?

FULLY LOADED:PP = (4000 psi 3000 psi) / 6PP = 1000 psi / 6PP = 167 psiThus, any time the pilot line sees at least 167 psi, thecylinder could lower the load.UNLOADED:PP = (4000 psi 0 psi) / 6PP = 4000 psi / 6PP = 667 psiThus, at least 667 psi will be needed to lower thecylinder when it is unloaded.

Sample Ratios:10:1

Thermal Setting Counterbalance valves have abuilt-in thermal relief valve that compensates for theexpansion of oil, due to temperature, by bleeding offexcess pressure. In other words, the thermal setting isthe pressure that the counterbalance will unload at ifno pressure is present at the pilot port. Obviously, thissetting should be above the holding setting. The ParkerMHC counterbalance valves are automatically set1000 psi above the holding setting of the valve. You donot specify this setting, only the holding setting.For the CB101 Series, you do specify the Thermal/Crack setting in the model code. The holding setting(maximum load induced pressure) is 70% of thatspecified setting. Example: Hold at 3000 psi, crack at4285 psi. For the E2 Series, you specify the Thermal/Crack setting in the model code. The crack setting(maximum load induced pressure) should be 1.3 timesthe hold. Example: Hold at 3000 psi, crack at 3900 psi.Pilot Area The pilot pressure required to lower thecylinder when fully loaded and unloaded can also bedetermined before applying the valve. The pilot pres-sure can be determined by the below equation:

Motor ControlsCounterbalance valves are used in motor circuits tostop overrunning loads and prevent cavitation. Sincehydraulic motors leak internally, the counterbalancevalve by itself cannot be used to hold the load. So, amechanical brake is used to hold the load on the motorin place, as shown below. Some typical applicationsinclude winches, swing drives, conveyor control andtraction drives. For applications in closed loop motorcircuits, vented spring cavities are required.

OperationFree flow to the motor is allowed through the internalcheck valve. In the controlled flow direction, the oilpasses across a metering poppet. The position of themetering poppet is determined by an external pilotsignal from the other side of the motor. In an open loopmotor circuit, this pilot signal will be a 1:1 ratio. Thereason an equal ratio pilot signal is utilized is toprovide positive control as well as to release mechani-cal brakes (when used in a braking circuit). In applica-tions where the motor will see overrunning loads inboth directions (such as a traction drive circuit), a dualMMB or two single MMB valves must be used.

Brake Applications

movement of the motor prior to the release of thebrake, an equal area ratio counterbalance is used. Todemonstrate lets look again at the above example witha 10:1 Ratio Counterbalance valve installed and amaximum thermal setting of 3000 psi.10:1 Example

NO LOADPP = (TS L) / RPPP = (3000 psi 0 psi) / 10PP = 3000 psi / 10PP = 300 psi

2000 PSI LOADPP = (TS L) / RPPP = (3000 psi 2000 psi) / 10PP = 1000 psi / 10PP = 100 psi

Thus, when there is no load on the motor, the counter-balance opens at 300 psi, or just as the brake is beingreleased. When there is a 2000 psi load on the motor,the counterbalance will start to open with a pilotpressure of 100 psi. The brake requires 300 psi, so themotor can start to rotate before the brake is released,causing wear on the brake. To offset this problem, youcould increase the maximum thermal setting to 5000psi, but this is very inefficient.1:1 (Equal Area) ExampleEqual area counterbalance valves are used primarilyin brake applications to avoid the wear problemdescribed above. With an Equal Area counterbalancevalve, there is no thermal relief valve, and there is nodifferential area to work on. In other words, the coun-terbalance valve only opens when the pilot pressure isgreater than the valve setting. The applied load hasnothing to do with the pilot pressure required. Thus youwill want to choose a pressure setting for the equalarea counterbalance valve that is just slightly abovethe brake release pressure (usually 350 psi).In our example, the valve would be set at 350 psi. Thiswould allow the brake to release before the counterbal-ance allows the load to move. Since the equal counter-balance valve always opens at 350 psi pilot pressureand is not dependent on the load, it is the best valvefor brake applications.Large Pressure Spike Application Keep in mindthat equal area counterbalance valves do not have abuilt-in thermal relief valve. As such, if there are largepressure spikes caused by the stopping of heavyloads, then a ratioed counterbalance, such as a 10:1should be used. In most cases these are non-braketype applications.

When the directional control valve is shifted, hydraulicpressure (usually 300 psi) releases the mechanicalbrake and allows the load to be moved. The counter-balance valve needs to provide adequate back pres-sure to open the brake, then immediately counterbal-ance the load. Ideally, the brake will be disengagedbefore the motor begins to rotate. If this sequence isnot achieved, the motor will try to rotate against theapplied brake reducing the life of the brake. This wouldbe the equivalent of trying to drive with your emer-gency brake applied. Remember that hydraulic motorsare equal area devices. So, in an effort to avoid the
