Lift Check Valve
Effectively preventing medium from backflow, the lift check valve is suitable for the application on the pipeline of petroleum industry, chemical industry, hydraulic power plant to control water, gas, oil and other corrosive medium. Using under high pressure is also available with this valve.
1.The valve disc moves up and down along the midline of the valve body. Under the pressure of the fluid which flows in one direction, the valve disc will be raised up from the sealing surface of the valve seat. If there is backflow, the valve disc will return back to the valve seat to cut off the medium.
2.To further reduce the impact, the lift check valve is engineered with piston dashpot, which is installed with spring.
3.There are small holes on the piston. When the piston is moving, the medium will flow slowly, which will reduce the impacting force to the valve greatly .
