This is three piece internal threaded ball valve with high platform, after being equipped with actuators, it can be widely used in electric, water, food, pneumatic, chemistry industries. Fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the passage of the medium will not cause the erosion of the sealing surface of the valve.

1.Fluid resistance is small, and the coefficient of resistance is equal to that of the same length.

2.Simple structure, small size and light weight.

3.Close and reliable, ball valve sealing surface material widely used plastic, sealing well, in the vacuum system has also been widely used.

4.Easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.

5.Easy maintenance, valve structure is simple, the sealing ring is generally active, demolition and replacement are more convenient.

6.In the fully open or fully closed, the ball and valve seat sealing surface and the dielectric isolation, the media through, will not cause the valve sealing surface erosion.

7.Suitable for a wide range of sizes from small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied

A customer in Pakistan purchases check valves, gate valves, pipe fittings, etc.

project description:

The client in this case is from Pakistan and is a large-scale local valve distributor. They have their own store locally and often import some valves from abroad to store or supply to local customers.

This client has cooperated with WESDOM many times. Almost every once in a while, they will contact the foreign trade salesman of WESDOM. They bought a batch of valves from WESDOM and stocked them in their store.

Through many cooperations with WESDOM, the two sides have established a very close cooperative relationship. Of course, they contacted WESDOM without hesitation, and purchased check valves, gate valves, pipe fittings, etc. from WESDOM.

Client feedback:

We have worked with WESDOM many times and have been very satisfied each time. We are very willing to maintain a long-term cooperative relationship with WESDOM.
