Deceleration Valves / Deceleration and Check Valves
These valves are available either with or without an integral check valve which allows free reverse flow. Flow rate
through the valve is regulated by the movement of the spool, which is operated by a cam. When the spool is
depressed, the flow is decreased in Normally Open type valves and increased in Normally Closed type valves. Their
principal use is to control the speed of actuators in machine tools and similar applications.
- Drain Port Back Pressure: Limit the drain port back pressure to 0.1 MPa (15 PSI).
- Bypass throttle valves: To allow a metred flow between ports even when the flow is stopped by the spool.
- Total Leakage at Spool Fully Closed: [Viscosity:20 mm2
