Resilient seal before compression.

Resilient seal after compression.

MECHANICAL RETRACTION & COMPRESSIONASSURES NO-LEAK STREAM SEPARATION ANDLONGER SEAL LIFE

General's Four-Way does not rely on line pressure orexternal hydraulic pressure for positive sealing. Theseating elements, or slips, move perpendicularly againstthe face of the ports. The seals themselves are highlyresilient elastomers which are either bonded ormechanically retained in the slips. Retraction of the slips,away from the body prior to cycling prevents frictionand abrasion which can damage seals. There is neverany sliding or rubbing of the seals against the valve bodyor ports. Metal-to-metal secondary seating preventsovercompression of the resilient primary seal.

MAINTENANCECUTS OPERATINGAND DOWNTIMECOSTS

Because the seatingsegments are mountedvia dove-tailed connec-tions to the plug, theymay be removed fromthe top or bottom andexamined without havingto take the valve from theline or disturb theactuator. This addedflexibility allows the valveto be installed upsidedown for easy access toactuator and slips.

FAST CYCLING

Fast and easy operation by hand or automaticallywith electric motor or hydraulic actuators is possible.Lower cycling torque permits use of smaller and lessexpensive power actuators.

The standard gear operated Four-Way is NOT selflocking, therefore it is recommended that all manuallyoperated Four-Way Diverter Valves be equipped with alatching device to maintain seating position when thevalve is unattended. This item is available as an option(see page 8). When sold as a motor ADAPTED valve besure to select ONLY self-locking actuators.

Note: Watch for our exclusive features stamp, anotherindication of General Valve's continued leadership.

CONTINUOUS FLOW CIRCULATIONMAINTAINED THROUGH CYCLING

Illustration 1Valve is seated. Flow streams completely separated.

Pressure gauge in body would indicate reducedpressure.

As the valve is unseated the plug is raised and bothslips are retracted. Plug and slips begin to turn. Slips andresilient seals are fully retracted away from body.Pressure gauge would indicate line pressure.

Illustration 2At this point in the cycle, the hole through the plug

allows the flow to pass directly from the inlet port to theoutlet port. Both slips and plug are designed so that theflow is not appreciably restricted when cycling. Pressuregauge would indicate line pressure.

Illustration 3Plug and slips in fully rotated position. Plug moves

down, expanding the slips against the body. Flow streamsare completely separated. As the seals trap fluid betweenthem and volumetric space increases the body pressuregauge would once again indicate less than line pressure.

Note: Valve position is quickly identified with a top-mounted flag. Position-indicator switches are avail-ablefor remote locations. (see page 8)

AUTOMATIC PRESSURE GAUGE FOR OUICK CHECK OF SEAL INTEGRITY

General's Four-Way Diverter uses the reliable pressuregauge method of checking for positive sealing to assuremetering accuracy. The gauge automatically indicates sealcondition each time the valve is seated during proving, evenin low differential operating conditions.

The pressure gauge connects to the body cavitybetween the valve slips. As the slips expand in the divertedposition, the resilient seals contact the valve body, trappingthe fluid between them. Further expan-sion of the slipsduring valve seating compresses the seals further. Theresulting increase in volumetric space between the slips,without an increase in the amount of fluid, will cause a dropin pressure.

Any leakage through either seal permits additional fluidto enter the body cavity, causing an immediate increase incavity pressure back to line pressure. Even the most

minimal fluid leak will register on the gauge immediately.A pressure switch may be used to supplement the gaugemethod as an option (see page 9).

HYDRAULIC ACTUATORHGO

General Valve Company Four-Way Valve can besupplied with hydraulically powered gear operators. TheGeneral Valve Hydraulic Gear Operator (HGO) is customdesigned and engineered tomaximize reliability whileminimizing installation and maintenance costs.

All actuating components are contained in a rugged,compact, explosion-proof module designed to withstandrough handling and hostile environments. The systemoperates efficiently and quietly and can be installed orretrofitted on any existing gear-operated Four-Way Valve.

The self-locking HGO can operate at speeds of up to900 rpm. See page 10 for performance data.

HYDRAULIC POWER SUPPLIESHPU

General Valve's electric or air-driven power suppliesare specifically designed and manufactured by GeneralValve to power General's Hydraulic Actuators. Usingstandard components as building blocks, the powersupplies satisfy a wide range of operating parametersreliably and economically.

STANDARD HYDRAULIC FEATURES

Each power supply features an integrated hydrauliccontrol module composed of cartridge-type compo-nents,many of which are interchangeable with General Valvehydraulic actuators. This safe, easy-to-maintain moduleminimizes exposed piping joints, and reduces costlyparts inventory.

STANDARD ELECTRIC FEATURES

MANUAL GEAR-OPERATEDLATCHING DEVICE

The standard gear operated Four-Way is NOT selflocking, therefore it is recommended that all manuallyoperated Four-Way Diverter Valves be equipped with alatching device to maintain seating position when thevalve is unattended. This item is available as an option.

The device uses a reversible latching pawl which can bedentented in mid position to allow free handwheel spin.At end of operation simply release pawl to latch valve ineither seated position.

TWO METHODS OF CHECK ING FORSEAL INTEGRITY

1) LOCAL MONITORING METHOD WITH AUTOMATICPRESSURE GAUGE

General's 4-Way diverter valve uses the pressuregauge method of checking for positive sealing toassure metering accuracy. This method is usefulwhen in close proximity to the valve and is discribedfully in the beginning of this catalog. (see page 3)

This 12 volt DC Gear Operator is ideal for repeatableproves with portable meter provers. It has no belts, sothere's no bounce-back.

General Valve Company's Direct Current Gear Operator isa battery powered actuator and control system (availablewith optional power pack) designed to be mounted on 2inch through 6 inch ANSI 300/600/900 General 4-Waydiverter valve gear operators and to operate 4-Way valvewith DC power DCGO's are capable of self-locking speedsin excess of 500 rpm. See page 10 for performance data.

Having the abilityto provide thevalve, actuatorand power packenhances thedependability ofour equipmentand simplifiesyour engineeringprocurement andservice.

2) REMOTE MONITORING METHOD WITHDIFFERENTIAL PRESSURE SWITCH

A differential pressure switch may be added, whichprovides the user with the ability to monitor the bodycavity pressure from a remote location and/orinterface with other electrical devices.

3. For satisfactory valve operation the line operatingconditions MUST REMAIN CONSTANT during sealintegrity check.

4. Do not attempt to verify seal integrity by bleeding bodycavity pressure to atmosphere when line pressureexceeds 100 psi.

5. Cavity pressure need not drop to zero while seated.6. Dissimilar pressure drop can be expected in each
