HSPEC16-32 Valve

SYMBOL:HSPEC16-32 Valve symbol


A high pressure, proportional, solenoid-operated, 3-way, normally-closed, flow control, screw-in hydraulic cartridge valve intended for post-compensated applications with load-sense systems. In post-compensated systems, the load-sense port 1 of the HSPEC16-32 valve is connected to the highest load, which maintains flow sharing when flow demand exceeds flow supply. Pressure compensation value of the valve defined as pressure difference between inlet and load sense ports is provided by appropriate setup of a pump load sense control or by additional pressure compensator valve, one for the whole system, in case the pump is non-adjustable.

When de-energized, the HSPEC16-32 blocks flow from port 3 to port 2. The valve will regulate flow out of port 2 regardless of load pressure with flow rate proportional to current applied to the solenoid.
