Electric metal sealed fixed ball valve

Product Name: Electric Metal Sealed Fixed Ball Valve Product model: Q947H/Q947Y Ball valves are used in the extraction, refining, processing, and pipeline transportation systems of oil, natural gas, coal, and ores; In the production of chemical products, pharmaceuticals, and food; Ball valves are used in power production systems for hydropower, thermal power, and nuclear power; Ball valves are used in the water supply, drainage, heating, and gas supply systems of cities and industrial enterprises; In the drainage and irrigation system of farmland; Ball valves are widely used in metallurgical production systems and are important mechanical products closely related to production and construction, national defense, and people's lives. Ball valves are used in various pipeline systems to cut off or connect the flow of media, allowing the media to be transported to designated points according to predetermined procedures. The fixed ball valve adopts an elastic floating valve seat structure, and the ball only drives one degree of freedom around the valve stem. When the valve is closed, it will not produce excessive sealing pressure with the valve seat under medium pressure, which will cause damage to the sealing surface. Therefore, high-pressure and large-diameter ball valves can be manufactured. A fixed ball valve with a nominal diameter of 200 should be selected.

Products Details

A. Full bore and reduced bore: Users can choose between full bore and reduced bore ball valves, which are about 30% lighter in weight than full bore ball valves and can reduce pipeline load and cost.
B. Dual directional sealing and drainage function: The valve seat is sealed with a spring pre tightened dual piston upstream and downstream medium pressure, allowing the valve to achieve dual directional sealing. The middle chamber can be emptied for maintenance or drainage.
C. Anti static structure: Soft sealed ball valves generate static electricity during the opening and closing process. Therefore, ball valves used in flammable and explosive situations require an anti-static structure.
D. Refractory structure: This structure forms a metal to metal hard seal after the soft sealing material is burned out in the event of a fire, effectively preventing the media from flowing out and causing greater losses.
The characteristics of metal hard sealed fixed ball valves:
1. Adopting a movable metal valve seat structure with cylindrical or waveform spring preloading, the sealing pre tightening force is designed reasonably and the closing and opening are flexible, effectively ensuring the reliability of the seal.
2. The use of a special structural device on the valve stem not only ensures that there will be leakage at the filling area, but also prevents the valve stem from coming out.
3. According to user needs, it can be designed to adapt to media such as dust (including solid particles) and slurry, making the ball valve more wear-resistant and high-temperature resistant.
4. It has fire and anti-static functions.
5. The structural ball valve should be used in the specified flow direction.A. Full bore and reduced bore: Users can choose between full bore and reduced bore ball valves, which are about 30% lighter in weight than full bore ball valves and can reduce pipeline load and cost.

2 piece ball valve flange end

A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a "floating ball") to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.[1] The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status
