Description
A forged steel lift check valve is a type of valve designed to allow fluid to flow in one direction and prevent backflow. Made from highstrength forged steel, it is durable and suitable for high-pressure and high-temperature applications. Its lift mechanism ensures minimal flow resistance, making it ideal for industries like oil, gas, and power generation. The compact design allows for easy installation and maintenance.

Benefits Application
- Lift Check Mechanism: The valve disc lifts off the seat to allow forward flow and returns to the seat to block reverse flow.
- Self-Operating: Automatically operates based on the differential pressure across the valve.
- Non-Slam Operation: Designed to minimize water hammer and provide smooth flow.
