2FPH55 - Flow regulator

Pressure compensated regulator/diverter, priority style. solenoid switch Up to 160 L/min (42 USgpm) • 350 bar (5000 psi)

Description

The 2FPH series of priority flow regulator valves gives full control of regulated flow plus remote selection of priority flow and adjustable pressure limitation of the regulated line.

Operation

Inlet flow passes through the adjustable orifice and the radial holes in the spool/ sleeve assembly then out of the regulated port. The pressure drop across the orifice is sensed at each end of the spool, producing a force which, at the required flow rate, overcomes the spring force. The resultant movement of the spool regulates the flow by opening the radial valve ports to the bypass port and closing the regulated flow ports. The solenoid valve vents the spring chamber to a drain line and in its NORMAL (de-energized) mode all inlet flow is diverted to the bypass port. The pre-set regulated flow is selected by energizing the solenoid. The adjustable relief valve vents the spring chamber at the pre-set pressure and diverts the flow to the bypass port. It may be necessary to fit a 10 bar check valve in the bypass or regulated line to ensure the valve switches fully.

Features

Line body construction with three ports allows direct connection into hydraulic systems. Leakproof adjust screw gives easy, accurate adjustment to required flow setting. Remote functional selection with solenoid operation. Adjustable relief valve gives system protection. Hardened and ground working parts give accurate flow control and long working life.
