The LPFR-10-K-4 is an L Series pressure compensated flow regulator cartridge valve for a C10-3 cavity. It is rated for 4 gpm and a 3,625 psi operating pressure, with a 1-1/2 in adjustment knob and an anodized aluminum alloy body rated for -22°F to +250°F.
A plain needle valve passes more flow when the pressure drop across it rises and less when it falls, so actuator speed changes with load. A pressure compensated flow regulator adds a compensator spool that holds a steady pressure drop across the metering orifice. The result is a steady flow from the regulated port as load pressure changes, which keeps cylinder and motor speeds consistent from one cycle to the next.
The C10-3 cavity gives the valve three ports: inlet, regulated outlet and a third port for flow above the regulated amount. That excess flow can feed another circuit or return to tank, so the pump does not have to push it over a relief valve.
The 1-1/2 in knob lets you set the regulated flow by hand. No ported body is listed for this part number, so it fits a manifold or line body machined for the C10-3 cavity. Confirm your cavity, flow and pressure needs before ordering.
