Stainless steel hard sealed ball valve

Stainless steel hard sealed ball valveIt is a stainless steel ball valve with a metal to metal material pairing for the sealing pair (i.e. valve seat sealing surface and ball sealing surface). Suitable for devices and pipelines for high temperature and high pressure water, steam, oil, viscous and granular media.

The Q41W national standard flange type hard sealed ball valve can solve the need for media that need to travel above 300 degrees. The sealing degree between the ball and the valve seat determines the quality of this hard sealed ball valve. Therefore, the polishing of the ball valve needs to be very precise, especially in the mining, refining, processing, and pipeline transportation systems of oil, natural gas, coal, and ore; In the production of chemical products, pharmaceuticals, and food; In the power production systems of hydropower, thermal power, and nuclear power; In the water supply and drainage, heating, and gas supply systems of cities and industrial enterprises; In the irrigation and drainage system of farmland; Widely used in the metallurgical production system, it is an important mechanical product closely related to production construction, national defense construction, 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 specific points according to predetermined procedures.

Q41HStainless steel hard sealed ball valveValve body material: stainless steel 304, 304L, 316, 316, etc.

Drive modes: manual, pneumatic, hydraulic, electric.

1. The valve seat adopts a plate spring loaded sealing structure, which can use high temperature and granular media;

2. Adopting a bottom mounted valve stem and equipped with an inverted sealing structure, it can ensure reliable sealing at the packing point;

3. The ball can be designed as an anti-static structure, with conductive springs installed between the ball and the valve stem, as well as between the valve stem and the valve body, to prevent static electricity from igniting flammable substances and ensure system safety;

4. The sphere and sealing surface can be treated by nitriding, welding, spraying and other methods to meet different process requirements;

5. An auxiliary sealing structure can be installed at the valve seat of the ball valve. A grease injection valve can be added to the valve seat and stem for temporary sealing in emergency situations, and the stem can be extended as needed to be suitable for underground installation;

6. Pneumatic and electric actuators can be installed to achieve centralized and remote control.
