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
