SOLENOID PROPORTIONAL FLOW CONTROL VALVE, POPPET, NORMALLY CLOSED, PRESSURE COMPENSATED

Overview

Description

The HSPEC10-34X is a high pressure, proportional solenoid-operated, poppet type, restrictive type, pressure compensated, normally closed flow control, screw-in hydraulic cartridge valve with built-in damping and load holding features.

Operation

With inlet at port 3 the valve will regulate flow out of port 2 regardless of load pressure with flow rate proportional to current applied to the solenoid. Port 1 must be connected to port 3 to provide load sense function for the compensator. When de-energized, the valve blocks flow from port 3 to port 2 while allowing free flow in opposite direction.

Note: Do not use an orifice disc wth this product.
