Compact Motion Control Valves - Pilot to Open Check Valves - Single acting

A-VSO-SE-LB

RE18307-10-01(2023-10-25)
Description

Flow is allowed to pass from A to A1 when pressure at A rises above the spring bias pressure and the poppet is pushed from its seat. The valve is normally closed (checked) from A1 to A; when sufficient pilot pressure is present at B-B1 the pilot piston acts to push the poppet from its seat and flow is allowed from A1 to A. Precision machining and hardening processes allow virtually leak-free performance in the checked condition.

In case of valve application in redundancy systems it is especially recommended to use version with sealed pilot piston.
