Product Overview
Q61F handle welded ball valve are widely used in various fields. lts superior quality and high performance stability can not be achieved by ordinary cast steel ball valves. Its service life is much
longer than that of cast steel ball valves. Fully welded ball valves are widely used in various pipeline
equipment such as city gas, city heat supply, petrochemical industry, shipbuilding, steel, pressure regulating station, power plant, etc. Fully welded ball valves can be buried directly underground
without building large valve wells to reduce project cost and avoid personal injury when operating the
valves. Fully welded ball valves can operate reliably for a long time. Comparing with the same specifications in the same industry, the valve body is small and has a good appearance.
Structural Characteristics
Q61F Handle Welded Ball Valve is an integral, fully welded ball valve with no external leakage. Since the seat is composed of PTFE sealing rings and springs, it is highly adaptable to changes in pressure and temperature and will not cause any leakage in its service range. The machining process of sphere is tracked and detected by advanced computer tester with high precision. As the valve body material is the same as the pipe material, there will be no uneven stress, no deformation due to earthquake and when the vehicle passes through the ground, and the pipe is agingresistant. The sealing ring body is made of PTFE with 20% C (carbon) content to ensure no leakage (0%).
