Product Description

Lift type rubber lined check valve, rubber lined check valve, lift type check valve, check valve. H41J lift type rubber lined check valve is specially used to control the general corrosive medium, the body cavity surface is covered with a variety of rubber to choose from, with high strength, good corrosion resistance; It is suitable for different working temperatures and fluid pipelines to prevent the one-way opening and closing of the medium countercurrent on all kinds of pipelines or equipment. Check valve is a kind of automatic valve that relies on the flow of the medium itself and automatically opens and closes the valve disc to prevent the reverse flow of the medium.

Installation precautions:
When placing the pipeline, attention should be paid to making the passing direction of the clamp check valve consistent with the flow direction of the fluid;
Install it in the vertically placed pipeline. For lines that are placed horizontally, place the sandwich check valve vertically;
Use a telescopic tube between the clamp check valve and the butterfly valve, never connect it directly with other valves;
Within the operating radius of the valve plate, avoid adding pipe joints and blockages;
Do not install a reducer in front of or behind the clamp check valve;
When installing the clamp check valve near the elbow, be careful to leave enough space;
When installing a clamp check valve at the pump outlet, drain at least six times the valve diameter of the space to ensure that the butterfly plate is finally subjected to fluid action.

Lift type rubber lined check valve common faults are: valve disc broken;
medium backflow.


The way to prevent is to use the valve disc as a ductile material of the check valve.
The reasons for the backflow of the medium are: damage of the sealing surface;
clamping impurities. Repair the sealing surface and clean the impurities, you can prevent backflow.
