Audited Supplier Used in natural gas, oil products, chemical industry, metallurgy, urban construction, environmental protection, pharmaceutical, food and other industries, the anti-sulfur series products are suitable for hydrogen sulfide medium, impurities, serious corrosion of natural gas long-distance pipeline. The ball valve is a new generation of high performance, suitable for long-distance transmission pipelines and general industrial pipelines, its strength, safety, resistance to harsh environment, etc. in the design of special consideration, suitable for all kinds of corrosive and non-corrosive media. Compared with the floating ball valve, it works, the fluid pressure in front of the sphere of all is passed to the bearing force, will not make a sphere to the seat to move, so the seat will not bear too much pressure, so the fixed ball valve torque is small, the seat of the small deformation, stable sealing performance, long service life, applicable to high pressure, large diameter. Advanced spring pre-seat assembly with self-tightening characteristics for upstream sealing. Each valve has two seats and can be sealed in each direction, so installation is two-way with no flow restriction.
The valve has two and three pieces of two body structure, the flange is connected with bolts, sealed with enhanced PTFE inserted into the stainless steel ring, ring back without spring to ensure that the seat close to the ball, keep sealed. There are no PTFE bearings on the upper and lower stem to reduce friction and save labor in operation. There is no adjusting plate at the bottom of the small shaft to ensure the joint position of the ball and the sealing ring. Full size: valve flow aperture to line id for line cleaning.
