Hard Seal Flanged Pneumatically Actuated Ball Valve

Description of Hard Seal Flanged Pneumatically actuated Ball Valves

The pneumatic hard-sealed flange ball valve is suitable for two-position cutting and adjustment occasions. The connection between the ball valve and the actuator adopts a direct connection. A pneumatic metal seal flange ball valve is mainly suitable for working conditions with high temperatures above 250 degrees. Pneumatic hard-sealed flange ball valve has the advantages of simple wiring, compact structure, small size, lightweight, low resistance, stable and reliable action, etc. Pneumatic hard-sealed flange ball valves are widely used in the mining, refining, processing, and pipeline transportation systems of oil, natural gas, coal, and ores; in the production of chemical products, medicine, and food; in the power production systems of hydropower, thermal power, and nuclear power; cities and industries In the enterprise’s water supply and drainage, heating, and air supply systems.

Features of Metal Seal Flanged Pneumatic Actuator Operated Ball Valves

Pneumatic metal seal flange ball valves should be used according to the specified flow direction.

The valve stem with a special structural device not only ensures leakage at the filling point, but also prevents the valve stem from falling out.

It has fireproof and antistatic functions.

According to the needs of the user, the structure can be designed to adapt to media such as dust (including solid particles), slurry, etc., so that the ball valve has better wear resistance and high temperature resistance.

It adopts a flexible movable metal seat structure with cylindrical spring or wave spring preload. The sealing preload force is reasonably designed and the closing and opening are flexible, effectively ensuring the reliability of the seal.
