The counter-flow direction is blocked. When pressure is applied to control port X, the ring chamber flow from B to A is released. The pilot control ratio is 6:1.

Function

When no pressure is applied to the X-port, the flow from B to A is blocked, because the pressure in B is also effective on top of the poppet.

Pressurising the X-port relieves the area on top of the poppet to the drain port and allows flow from B to A. The seat design of the SVLB valve series provides leakfree separation of port A and B in the closed position.
