【 Ball Valve 】 Features: (1) Low fluid resistance, full bore ball valves have almost no flow resistance. (2) Simple structure, small size, and light weight. (3) Tight and reliable. It has two sealing surfaces, and currently, various plastics are widely used as sealing surface materials for ball valves, which have good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems. (4) Easy to operate, quick opening and closing, only need to rotate 90 ° from fully open to fully closed, making it convenient for remote control. (5) Easy to maintain, ball valve structure is simple, and the sealing ring is generally movable, making disassembly and replacement relatively convenient. (6) When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface. (7) Widely applicable, with diameters ranging from a few millimeters to several meters, suitable for applications from high vacuum to high pressure. (8) Due to the wiping property of ball valves during opening and closing, they can be used in media with suspended solid particles.

Overview of Fixed Ball Valve:

Fixed ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipelines. Its strength, safety, and resistance to harsh environments have been specially considered in the design, and it is suitable for various corrosive and non corrosive media. Compared with floating ball valves, during operation, all the force generated by the fluid pressure in front of the valve on the ball is transmitted to the bearing, which will not cause the ball to move towards the valve seat, so the valve seat will not bear excessive pressure. Therefore, fixed ball valves have smaller torque, smaller valve seat deformation, stable sealing performance, and longer service life, making them suitable for high-pressure and large-diameter applications. Advanced spring pre seat components with self tightening characteristics achieve upstream sealing. Each valve has two valve seats, which can seal in each direction, so there is no flow restriction during installation, and it is bi-directional.

Technical parameters:

This valve has two types of valve body structures: two-piece and three piece. The middle flange is connected by bolts, and the seal is made of reinforced polytetrafluoroethylene embedded in a stainless steel ring. There is no spring at the back of the steel ring to ensure that the valve seat is tightly attached to the ball, maintaining a seal. There are no PTFE bearings on both the upper and lower valve stems, reducing friction and making operation effortless. There are no adjustment plates at the bottom of the small shaft to ensure the joint position between the ball and the sealing ring. Full bore: The valve flow aperture is consistent with the inner diameter of the pipeline for pipeline cleaning.
Applicable media: water, gas, oil, natural gas, and acid-base corrosive media.
Applicable temperature: -196~350 ℃
Drive modes: manual, pneumatic, electric, hydraulic, etc.
Nominal diameter: DN25-8001 '~32'

Main features:

(1) Effortless operation: The ball is supported by upper and lower bearings, reducing friction and eliminating excessive torque caused by the huge sealing load formed by the inlet pressure pushing the ball and the sealing seat.
(2) Reliable sealing performance: The PTFE single sex material sealing ring is embedded in the stainless steel valve seat, and the metal valve seat end is equipped with a spring to ensure sufficient pre tightening force of the sealing ring. When the sealing surface of the valve wears out during use, the valve continues to ensure good sealing performance under the action of the spring.
(3) Fireproof structure: In order to prevent the PTFE sealing ring from burning out due to sudden heat or fire, causing significant leakage and fueling the fire, a fireproof sealing ring is installed between the sphere and the valve seat. When the sealing ring burns out, the valve seat sealing ring is quickly pushed onto the sphere by the spring force, forming a metal to metal seal and achieving a certain degree of sealing effect. The fire resistance test meets the requirements of APl6FA and APl607 standards.
(4) Automatic pressure relief function: When the pressure of the stagnant medium in the valve chamber abnormally increases beyond the preload force of the spring, the valve seat will retract and detach from the ball, achieving the effect of automatic pressure relief. After pressure relief, the valve seat will automatically reset.
(5) Drain pipeline: Drain plugs L are installed on both the upper and lower parts of the valve body to check if there is any leakage in the valve seat. During operation, when the valve is fully open or fully closed, the pressure in the middle chamber can be relieved and the packing can be directly replaced; It can discharge the retained substances in the middle chamber and reduce the pollution of the medium to the valve. Auxiliary sealing setting system (please specify when ordering)
(6) This valve is designed with an auxiliary seat emergency sealing system. Once the seal is damaged or an emergency situation occurs and cannot be sealed, the corresponding sealing agent can be injected into the sealing surface through the auxiliary sealing system to repair the sealing surface and achieve emergency sealing. When the conveyed medium is unclean or contains a small amount of particles, in order to protect the sealing surface and ensure reliable sealing, corresponding cleaning agents or lubricants can be injected into this device to clean the sealing surface.
(7) Widely applicable for cutting off or circulating media in transportation pipelines such as food, medicine, petroleum, chemical, natural gas, steel, environmental protection, papermaking, etc. Corresponding cleaning agents or lubricants can also be injected into this device to clean the sealing surface.
