Description
1. Overview of Lift Check Valve
Lift check valves are automatic valves designed to prevent backflow by utilizing the fluid pressure difference and the valve disc’s weight for lifting and lowering. These valves are suitable for most horizontal pipelines, ensuring protection of upstream equipment. Their advantages include a simple structure, reliable operation, and convenient maintenance.
Applications:
- Horizontal pipelines in tanks
- Purification equipment
- Petrochemical, chemical, and metallurgical industries
- Power generation and light textile production
