Effectively preventing medium from backflow, the lift check valve is suitable for the application on the pipeline of petroleum industry, chemical industry, hydraulic power industry and power plant to control the medium flow like water, gas, oil and other corrosive product. Using under high pressure is also available with this product.
Benefits
1.The valve disc slides 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 have the flow cut off.
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 is conductive to the outstanding buffering performance of the high pressure life check valve.
