DN40 Two Way Stainless Steel Ball Valve Flange Stye PTFE / PCTFE Seal Material

Overview
The ball of the ball valve is floating. Under the action of the medium pressure, the ball can produce a certain displacement and be tightly pressed against the sealing surface at the outlet end to ensure the outlet end is sealed.

The structure of the floating ball valve is simple and the sealing is good, but the load of the ball bearing the working medium is all transmitted to the outlet seal. Therefore, it is necessary to consider whether the material of the ring can withstand the working load of the ball medium. The sphere may be offset. This structure is generally used for medium and low pressure ball valves.

The main features of the ball valve are its compact structure, reliable seal, simple structure, and convenient maintenance. The sealing surface and the spherical surface are often closed, not easily eroded by the medium, easy to operate and maintain, and suitable for general work such as water, solvents, acids and natural gas. Media, but also suitable for harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc., are widely used in various industries. The ball valve body can be integrated or combined.

1. It should ensure that the pipe is blown clean before installation.

2. When installing, make sure that the flow direction indicated by the arrow on the valve body should be consistent with the flow direction of the fluid.

3. This valve has been degreased. Store and keep clean when installing.

4. After the pipeline construction is completed, all the valves on the pipeline should be opened, and the residue in the pipeline should be thoroughly and thoroughly kept to ensure that the pipeline system is clean and free of debris.

5. The installation system diagram with the oil-free requirements should be degreased.

6. Slowly open and close during use.

7. If the precision parts such as the valve disc, valve seat and valve stem are worn or damaged, it must be repaired and replaced in time.

8. For parts such as gaskets and sealing materials, replace them with new ones each time.
