Welded ball valve

Product overview

Since the seat is composed of a carbonized Teflon seal ring and saucer spring, it is highly adaptable to pressure and temperature changes and will not cause any leakage within the marked pressure and temperature range. There are steel balls and springs between the stem and ball and between the stem and the packing box to maintain the conductivity of all parts of the valve and the body, allowing the current to pass through the area and release static electricity. Not only to avoid fire, but also to avoid corrosion, to complete temporary stoppage, in order to timely maintenance.

Product details

Structural features

Welded ball valve is a one-piece welded ball valve, no external leakage phenomenon, because the valve seat is composed of PTFE sealing ring and spring, so it has strong adaptability to pressure and temperature changes, and will not produce any leakage within the use range. The machining process of the sphere is tracked and detected by the advanced computer detector, so the machining precision of the sphere is high. As the valve body material is the same as the pipe material, there will be no uneven stress and deformation due to earthquake and vehicle passing through the ground, so the pipe is anti-aging. The sealing ring body is made of PTFE material with 20%C(carbon) to ensure complete leakage (0%).
