The check valves in the VNR Series are available with M5
(10-32 UNF), 1/8” and 1/4” ports. They must be used when it is
required to intercept a flow in one direction only. The design of these
valves is of the poppet type and this feature allows operation at low
pressures both when there is a free flow and during retention.
Materials used:
- OT58 (brass) body, Nickel Plated (1/4")
- Buna-N seals
- stainless steel spring
- internals brass
