Hydraulically Pilot Operated Check Valve Series SVLB
Catalogue HY11-3500/UK
Characteristics Hydraulically pilot operated check valves allow free flow from A to B. 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. Pressurizing 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. Features • Pilot operated check valve • Cavity and mounting pattern acc. to ISO 7368 • Dampening poppet optional • 5 sizes NG16 to NG50
provides shock-free unloading of the fluid, especially at high working pressure and large volumes. Connection for pilot line. Connection for pilot line. Code. RH.
When the valve poppet is open, the large cross-section allows high flow rates at low differential pressure. ⢠Different control ratios can be chosen with the NG6.
