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 opera-
tion 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
Quick exhaust valves are commonly used to increase the speed
of cylinders or for rapid depressurisation of tanks containing
compressed air. The models
VSO 425-M5
and
VSO 426-04
are specially designed for mounting on solenoid valves and
valves incorporating a 5/32” O.D. port. We recommend that a
silencer be mounted on the outlet (2931-M5).
Materials used:
-
OT58 (brass) body, Nickel Plated
-
Buna-N seals
