HYPD10-35 (Two Way Pilot Directional Valve, Normally Open)

A cartridge-style 2-way pilot-operated spool-type directional valve.


Unpiloted, the valve allows flow between ② and ③. The spring bias chamber is internally vented to ③. On remote pilot signal at ①, the valve shifts to open ② to ③ bidirectionally.

Note: back pressure at ③ will increase the pilot pressure required at ① to shift, at a ration of 1:1. Consult factory for applications where bi-directional flow is required when the valve is in the normal or spring-offset position.



Max. operating pressure:

240 Bar


See pressure drop vs. flow graph

Internal leakage:

82 cc/min.max. at 207 bar

Pilot pressure required:

To full spool shift:

For 4.1bar spring: 4.7bar

For 7.6bar spring: 8.6bar


(-40℃ to +120℃) with NBR material seals


Mineral-based fluids with viscosity of 7.4 to 420 cSt.
