Since the full welded ball valve seat is composed of a carbonized Teflon seal ring and a disc spring, it has strong adaptability to pressure and temperature changes, and will not cause any slippage within the marked pressure and temperature range. The processing of the sphere is tracked and detected by an advanced computer detector, so the processing accuracy of the sphere is high.
Due to the high quality ball valve body material is the same as the pipe material, there will be no uneven stress, and no deformation due to earthquakes and vehicles passing the ground, and the pipe is resistant to aging. The metal ball valve body of the sealing ring is made of RPTFE with a content of 25% Carbon, which guarantees no leakage (0%).
The direct-buried fully welded ball valves can be directly buried in the ground, instead of building high and large valve wells, only small shallow wells are set on the ground, which greatly saves construction costs and engineering time.
Size: 1/2"~16"(DN15~DN400)
Pressure: Class ANSI #150~900, PN10~PN150
Fully welded ball valves body material: Carbon steel, Stainless steel, Alloy steel, or others
Standard compliance: EN12516, DIN3357-1 or equivalents
End connections: Flanged Ends OR BW, SW
Direct mounting with pneumatic or electric actuators
Full port or regular bore; double block and bleed
The high quality ball valve is composed of a full welding body together with the RPTFE sealing which ensures the full welded ball valve can work well in there are countries or chemical substances.
The floating ball structure and the flexible seat will ensure the ball and the sealing connects each other tightly. Even when the pressure is not stable, the fully welded ball valves can also have good sealing.
The stem can be extended which is good for keeping the temperatures table.
