The quality of survival, integrity and development, with a collection of scientific research, design, manufacture, sales and service in one of the high-quality staff, strong technical force, advanced production technology. Sophisticated processing equipment, improve the detection equipment, a sound quality assurance system to ensure product quality and reliability. Security fully welded ball valve in various fields use are very wide, and its superior quality and performance stability is ordinary steel ball can not reach, life is far greater than steel welded ball valve welding ball valves are widely used in city gas , urban heating, petrochemicals, shipbuilding, steel, regulator stations, power plants and other types of pipeline equipment, can be buried in the ground, do not build tall valve well reduce the project cost, while also causing the operation of the valve can be avoided damage, long-term reliable operation welded ball valve used in the case of normal operational use of the valve, the warranty period of 20 years. Welded ball valve Technical Features 1, integral welded body structure, there will be no external leakage. 2, the valve seat by a PTFE sealing ring and springs changes in pressure and temperature adaptability within the operating range without any leakage. 3, stem anti-leakage structure, the bottom of the stem has a PTFE seal the puncture and an O-ring, there are two O-ring above, consisting of two PTFE gasket to ensure no leakage. 4, the same material as the body material and pipe stress does not appear uneven, it will not because of the earthquake and ground vehicles and sometimes through extrusion. 5, the body is light and easy to heat. 6, buried ball directly buried, do not build tall valve well, just set up a small shallow wells on the ground, saving construction costs and engineering time. 7, the valve can be adjusted according to the length and stem height pipeline construction and design requirements. 8, the ball very precise machining precision, easy operation, no adverse interference. 10, welded and flanged two connections. 11, Operation: Lever, gear (vertical / horizontal) 12, in the case of normal operational use of the valve, the warranty period of 20 years.
