Characteristics
This lift check valve is an automatic non-return valve with vertically lifting disc guided by inner sleeve to prevent medium backflow. Available in ductile iron, WCB carbon steel, 304/316 stainless steel with metal or soft PTFE/EPDM sealing. It features tight shutoff, high pressure and temperature resistance. Widely used for boiler feed water, steam, oil, chemical and high-pressure clean fluid pipeline systems.

Advantages
1.The surface sealing structure of this piston check valve can withstands high pressure and temperature. Fast closing prevents pump reversal and pipeline pressure loss, ideal for critical boiler and thermal pipeline systems.
2.The lifting one way valve built-in guide sleeve keeps disc moving vertically without jamming, stable long-term operation and low maintenance downtime.
3.Compact simple structure with easy seal replacement, small size fits narrow pump room and small-diameter precision pipelines.
Packing
Standard export wooden case packaging

Application Scenarios
This lifting type check valve is widely used in power plant boiler feed water lines, thermal steam circulation pipelines, petrochemical oil piping, high-pressure HVAC circulating water, compressed air systems, pharmaceutical pure water delivery and heat exchange pump rooms.
