HSF

Quick Overview

FLOW CONTROL VALVE

Max Pressure: 5000 PSI (350 bar)
Rated Flow Rate: 85 to 200 gpm (332 to 758 l/min)

The HSF valve is a non-pressure compensated adjustable orifice for adjusting flow in one direction and allowing free flow in the other direction. The valve is used as a unidirectional flow regulator.

As the knob is turned clockwise and counter clockwise, the adjustable screw moves in and out of the center of the sleeve-type check valve which has an orifice in it. Then flow is from port 1 to 2, pressure raises the sleeve, compressing the spring and allowing free flow. Turning the adjustable screw outward allows restricted flow from port 2 to 1.

This valve is constructed of steel parts. Operational parts are hardened and ground as required. It is designed for easy service and field repair.
