Flow Control Valves Technical Information High Pressure Flow Control - Pressure Compensated HFCV10-HRT OPERATION The HFCV10-HRT is a high pressure, fully adjustable, pressure compensated, restrictive-type flow control. This valve maintains a constant flow rate out of port 2 regardless of pressure variations at port 2 or port 1. An integral check valve allows unrestricted flow from port 2 to port 1. The valve can be adjusted from closed to fully open (5 turns) with counter-clockwise rotation of the adjustment screw. Regulated flow ranges are available pre-set from the factory in 1 LPM increments between 4-45 LPM (1.0-12.15 US gal/min). APPLICATIONS The HFCV10-HRT features fine adjustability and can be used for meter-in, meter-out applications to control actuator speeds.
