Two Piece Extended Welded Ball Valve
Product Description
Products Introduction.
Forged steel ball valves work by rotating the stem to open or block the valve. Can be full diameter ball valve, 90ºC Angle, ball valve switch light, small size, can be made into large diameter, reliable sealing, simple structure, easy maintenance, sealing surface and the sphere is often in the closed state, not easy to be eroded by the medium, widely used in various industries. Forged steel ball valve classification: low pressure forged steel ball valve, high pressure forged steel ball valve.
Suitable for: chemical, petroleum, natural gas, metallurgy, and other industries and hydrogen sulfide containing medium, impurities, severe corrosion of natural gas long distance pipeline.
Forged steel fixed ball valve is engineering and technical personnel more than 10 years experience of designing and manufacturing high pressure valve, using the latest international technology standards development, and is mainly used in oil and gas long distance pipeline and urban gas pipeline system, due to the unique characteristics of long distance pipeline with valve, thus fully considered in the design of the ability of the pipeline under stress, and security, the weathering resistance, Long-term use of reliability, sealing, structural design, operation modes are manual worm drive, pneumatic, electric, gas/liquid linkage, and all kinds of special control forms.
The ball is a fixed ball, the ball is grinded, polished and hardened by the envelope grinding ball process, separated from the valve stem, the valve stem is a slender shaft, the surface is hard treated, the axial load of the ball is transferred to the valve body by two larger self-lubricating dynamic bearings, so it is abrasion resistant, and the operation is flexible and low torque.
