How to Order
Description
A cartridge valve designed to allow free flow in both directions. The valve can be piloted to block flow in both directions. This valve can used as a load holding or blocking valve.
Operation
Pressure at ➀ or ➁ overcomes the spring-bias poppet and allows free flow between ➁ and ➀ or ➀ to ➁. When required the pilot pressure is achieved at ➂, the poppet is held closed to block flow between ➁ and ➀ and ➀ and ➁. The pilot area ratio port ➂ to ➀ is 2:1 and the area ratio port ➂ to ➁ is 2.8:1.
Features and Benefits
- Hardened poppet and sleeve for long life and low leakage.
- Industry common cavity.
