Flow Control Valves Technical Information
High Pressure Flow Control - Pressure Compensated
HFCV10-RT
OPERATION
The HFCV10-RT 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 1-11 LPM (0.26-2.9 US gal/min) and also at flows of 0.38 LPM (0.1 US gal/min) and 11.4 LPM (3.0 US gal/min).
APPLICATIONS
The HFCV10-RT features fine adjustability and can be used for meter-in, meter-out applications to control actuator speeds.
