HSNC

Quick Overview

NEEDLE CHECK VALVE

Max Pressure: 5000 PSI (345 bar)
Rated Flow Rate: 12.5 to 225 gpm (47 to 852 l/min)

A HSNC valve prevents the flow in one direction while providing an adjustable orifice in the other direction.

When differential pressure at port 1 is higher than at port 2, the main spool is forced against an inner-chamber spring and opens port 1 to 2. The spool travel (orifice opening) is adjustable by turning the knob counter clockwise (screw turns outwards) to increase flow. A reversal flow, with higher differential pressure at port 2, forces the spool closed and blocks flow.

The HSNC cartridge valve is constructed of steel parts. Operating parts are hardened and ground as required. The cartridge is designed for easy service and field repair.
