Product Details
Ball valve evaluates from the cock, the ball moves around the center-axis of stem by 90 when it works and closes. It’s mainly used in duct to cut off, regulate the flow and change the direction of flow medium.
1. Smallest resistance with the fluid-by zero in fact.
2. The ball is free to bare the high pressure when it closed.
3. Quickly to open and close (some components need only 0.05s-0.1s), to be assure to used in the automatic system of test bed.
4. Tightly connected components, with small volume and light weight.
The seal test is strictly executed as per the standard of GB/T13927-1992. All the products must be inspected to be qualified by the press at the proportion of 100%. And all delivered products are closed the air. It will be convenient to check the sealing function before the use.
To install the ball valve must be done by professional technician with qualification. The two end lines shall not be too misaligned. Otherwise, there will be excessive pipe installation stress, resulting in failure and damage. The accuracy and effective length of the thread must be strictly executed as per the standard of ISO228.
When installing, please pay attention to avoid valve deformation, and polytetrafluoroethylene raw material or threaded seal glue must be used to strengthen the sealing.
