Description

A cartridge valve designed to allow free flow in one direction while preventing flow in the opposite direction. Reverse flow can be achieved by reaching the required pilot pressure. This valve is commonly used as a load-holding or blocking valve.

Operation

Pressure at ➁ or ➂ overcomes the spring-bias poppet and allows free flow to ➀ or ➃ respectively. Flow in the opposite direction, from ➀ to ➁ or ➃ to ➂, is blocked by the poppet. When the required pilot pressure is achieved at ➁, the poppet unseats and allows flow between ➃ and ➂. When the required pilot pressure is achieved at ➂, the poppet unseats and allows flow between ➀ and ➁. The pilot piston area to poppet seat area is ➃ to ➀.

Features and Benefits
  • Hardened seat for long life and low leakage.
  • Industry common cavity.
  • Compact size.
