Dimensions in millimeters (mm)

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
