Application A lift check valve is used to prevent the backflow of any stream, whether it is liquid, gas, vapor, or any solidified stream. There is a certain pressure required to open the check valve. If the pressure becomes less, the valve will automatically close, or additionally, it prevents the stream from flowing in the opposite direction. |
Other The carefully selected materials and contemporary design make our check valve highly recognized. If our check valve cannot meet your choice, we can provide you with special made. |
Chief Features
Controlled by a plug that lifts as the valve fills up with media, the Lift Check Valve (or Piston Check Valve) is ideal for gas, liquid, air, and vapor pipeline connections. Available in horizontal, vertical, and angular body patterns, our lift check valves keep released media from returning when the plug returns to its original place.
The valve can be opened and closed automatically by medium force
Ss+ graphite or metal seal is used between valve body and valve cover, and the sealing is reliable
The sealing surface of valve seat and disc is overlaid with cemented carbide to improve the scouring resistance and prolong the service life of the valve
Lift check valve disc can also be spherical at high pressure
