Hydraulically Pilot Operated Check Valve - Series SVLB

The hydraulically pilot operated check valve series SVLB is based on Parker's comprehensive modular DIN cartridge system. It is mainly used to shut-off the cylinder.

Полное описание продукта

Parker's hydraulically pilot operated check valves series SVLB in cartridge design ensure a reliable shut-off of the cylinder for smooth operation. They 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.

Markets:
• Industrial

Features/Benefits:
• Proven design - allows a reliable cylinder shut-off
• Cavity and mounting pattern acc. to ISO 7368 - for quick and easy integration
• 5 sizes, NG16 to NG50 - makes selection easy
• Nominal flow up to 1800 l/min - optimum efficiency in relation to valve size
• Short delivery time for most variations - no warehousing necessary
• Pilot control ratio is 6:1
• Optionally with dampening poppet

Applications:
• Suitable for general hydraulic applications
• General presses

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 leak-free separation of port A and B in the closed position.
