Powrflow™ Flow Control Valves (Sub-Plate Mount) | |
|
Powrflow™ Subplate Mount Flow Control Valve - Pressure Compensated This flow control valve is pressure compensated to maintain constant flow of the valve regardless of pressure changing to the inlet or outlet port. Exclusive internal pressure balancing allows easy adjustment of flow setting under pressure. Pressure compensation will maintain preset flow with 1 to 5%, depending on the basic flow range, as long as there is 150 psi pressure differential between the inlet and outlet ports. The dial is calibrated for easy and repeatable flow settings. Continental Hydraulics' unique sharp edged orifice design means that the valve is immune to temperature or fluid viscosity changes. This valve is internally drained, therefore, eliminating the drain piping. Maximum Inlet pressure of 3000 psi; Available with or without return check valve; Maximum flow rates of 16.5 gpm; Sub-plate mounting interface is NFDPA 2F06. Valve is lockable.

Powrflow™ Pressure Control Valves These in-line valves come in 6 different varieties: Pressure Relief, Cross Port, Pressure Reducing, Pressure Reducing/Relieving, Pressure Sequence, and Counterbalance. | |
|
Powrflow™ Pressure Relief Valve - Pilot Operated This pilot operated pressure relief cartridge valve with balanced sliding spool provides accurate, smooth pressure regulation. The valve blocks flow from port 1 to port 2 until sufficient pressure is present at port 1 to force the pilot poppet from its seat, thus opening the valve. This cartridge relieve valve offers a smooth transition in response to a load change in a hydraulic circuit. Valve sizes are NFPA D03 and NFPA D05. Maximum Inlet Pressure is 5000 PSI; Pressure Adjustment Ranges are 50-1500 PSI and 100-3000 PSI; Maximum Flow Rates are 15 and 20 GPM. Series P*MSV-R Specifications and Options |

The valve allows free flow from the work port to the outlet port and blocks flow in the opposite direction. Free flow will be allowed from the outlet port to the work port when at least one-third of the load induced pressure is sensed in the opposing work port. Valve sizes are NFPA D03 and NFPA D05. Maximum Inlet Pressure is 5000 PSI; Pressure Adjustment Ranges are 50-1500 PSI and 100-3000 PSI; Maximum Flow Rate is 10 GPM. Series P*MSV-X Specifications and Options |

Powrflow™ Pressure Reducing Valve - Pilot Operated The pilot operated, hydraulic pressure reducing valve acts as a pressure regulating device for a secondary circuit. It utilizes a sliding spool and screw-in cartridge. The valve will allow flow from the inlet port to the controlled port until pressure exceeds the spring setting. Then the spool will start to restrict flow, causing reduced pressure in the controlled port. Valve sizes are NFPA D03, NFPA D05 and NFPA D08. Maximum Inlet Pressure is 5000 PSI; Pressure Adjustment Ranges are 50-1500 PSI (D03 only), 25-800 PSI (D05 only) and 100-3000 PSI; Maximum Flow Rates are 10, 20 and 40 GPM. Series P*MSV-PD Specifications and Options |

|
Powrflow™Pressure Reducing/Relieving Valve - Direct Operated This pilot operated hydraulic pressure reducing/relieving valve acts as a pressure-regulating device for a secondary circuit. It features a sliding spool and screw-in cartridge. This valve will allow flow from the inlet port to the controlled port until pressure in the controlled port exceeds the force of the spring bias. Then the spool will shift and restrict. This causes reduced pressure in the controlled port. The valve will maintain the same pressure as the force of the spring setting regardless of the pressure at the inlet port. In this mode, the valve will also relieve from the controlled port to the drain port, regulating pressure at the controlled port. Valve sizes are NFPA D03 and NFPA D05. Maximum Inlet Pressure is 5000 PSI; Pressure Adjustment Ranges are 50-1500 PSI, 50-3000 PSI and 50-5000 PSI; Maximum Flow Rates are 10 and 20 GPM. Series P*MSV-PDR Specifications and Options |

|
Powrflow™ Sequence Valve - Pilot Operated This pilot-operated, pressure sequence valve uses a screw-in poppet type cartridge with built-in free reverse flow check. The valve blocks flow from the inlet port to the outlet port until sufficient pressure is present at the sense port to force the pilot poppet from its seat, thus opening the valve. This sequence valve offers free reverse flow from the outlet port to the inlet port. Valve sizes are NFPA D03 and NFPA D05. Maximum Inlet Pressure is 5000 PSI; Pressure Adjustment Ranges are 50-1500 PSI and 100-3000 PSI; Maximum Flow Rates are 15 and 20 GPM. Series P*MSV-S Specifications and Options |
|
|
Powrflow™ Counterbalance Valve - Pilot Operated with Check The counterbalance valve utilizes a cartridge type, guided poppet, hydraulic operated, pilot assisted, counterbalance valve as a blocking or load-holding device for high pressure applications. This valve controls moving load and prevents it from running ahead of the pump and locking the load in any position. It also provides static overload and thermal expansion protection. This valve is a modulating device that allows free flow from the valve to the outlet port and then blocks reverse flow until pilot pressure inversely proportional to the load pressure is sensed at the opposite work port modulating out flow from the work port back to the valve. Valve sizes are NFPA D03 and NFPA D05. Maximum Inlet Pressure is 5000 PSI; Pressure Adjustment Ranges are 50-1500 PSI and 100-3000 PSI; Maximum Flow Rates are 15 and 20 GPM.
