Hydraulically Pilot Operated Check Valve - Series SVLB
*PRODUCT IMAGE IS REPRESENTATIVE PROVIDED BY THE MANUFACTURER. DO NOT MAKE BUYING DECISIONS SOLEY BASED ON THE IMAGE. PLEASE VERIFY SPECIFICATIONS MEET YOUR REQUIREMENTS.
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.
