How to Order
Description
A cartridge valve designed to block flow in both directions. Free flow can be achieved by reaching the required pilot pressure. This valve is commonly used in load holding or blocking applications.
Operation
In the steady state the poppet is held closed to block flow between
➀ and ➁ and ➁ and ➀. When the required pilot pressure is achieved
at ➂, the poppet is held open to allow free flow between ➁ and ➀ or
➀ and ➁. The pilot area ratio port ➂ to ➀ is 1.3:1 and the area ratio
port ➂ to ➁ is 1.8:1.
Features and Benefits
- Hardened spool and sleeve for long life and low leakage.
- Industry common cavity.
