H41H, H41Y type PN16 ~ PN100 steel valve lift control system in the production process is an important part of one of the media is one-way flow control pipe valve, stop the media back. 

 【Features】 
 1, H41H, H41Y-type steel lift check valve has a simple structure, reliable operation, easy maintenance, etc., are widely used in purification equipment, petroleum, chemical, metallurgy, electric power, textile and other manufacturing process 
 2, when the medium is shown by the arrow on the flow into the valve body, medium pressure valve in the valve to generate the upward thrust, the thrust is greater than when the medium gravity valve, the valve opens. After the media pressure when the valve flap in the valve disc with a force greater than its own weight in the valve before the pressure force on the valve, the valve closes, preventing the media back
