COUNTERBALANCE VALVE
• The P03MSV-C counterbalance valves with pilot assist are designed to control an overrunning load or hold a load in position by maintaining a back pressure on the outlet of the cylinder. An integral check valve allows for free flow in the reverse direction. Valve conforms to NFPA D03/ISO 4401-03 standard for valve mounting interface.
• This valve can also be used as a brake valve in hydraulic motor circuits for a controlled deceleration.
• Counterbalance valves should be set at least 130% of maximum pressure due to load.
• Backpressure adds to the valve setting by (1.0 + pilot ratio) times the backpressure.
• Reverse flow will open the check at about 25 psi [1.7 bar].
• 3.75 turns of adjustment CCW from Min. to Max. pressure setting.

1 • IDENTIFICATION CODE
Use mineral oil-based hydraulic fluids HL or HM type, according to ISO 6743-4. For these fluids, use NBR seals (code A). For fluids HFDR type (phosphate esters) use FPM seals (code G). For the use of other kinds of fluid such as HFA, HFB, HFC, please consult our technical department. Using fluids at temperatures higher than 176ºF [80ºC] causes a faster degradation of the fluid and of the seals characteristics.
The fluid must be preserved in its physical and chemical characteristics.
