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 overcomes the spring-bias ball and allows free flow to ➂. Flow in the opposite direction, from ➂ to ➁, is blocked by the ball. When the required pilot pressure is achieved at ➀, the ball unseats and allows flow between ➂ and ➁. The pilot piston area to poppet seat area ratio is 3 to 1.
