Lift Check Valve

Design & structural Features:
The H41H/H41W lift check valve is designed to control the unidirectional flow of medium in pipelines and prevent backflow. It is suitable for high-pressure and high-temperature conditions, with a working temperature range of -29°C to +550°C. The valve is widely used in petroleum, chemical, pharmaceutical, fertilizer, and power industries. Applicable media include water, oils, steam, and acidic fluids.
