Forged steel flange pneumatic valve valve industry technical characteristics _ pneumatic components factory

Pneumatic valve pneumatic pneumatic valve forged steel flange overview: the development and production of pneumatic components factory valve industry forged steel flange pneumatic valve is mainly suitable for oil and gas pipe of various systems of the road, cut off and on line medium, forged steel flange for the three type double pneumatic valve body weld connection, valve parts and body * * the massing, designed to avoid the valve connecting flange, thus the eradication of the leakage channels, avoid toxic and flammable medium leaking to the pneumatic valve and cause unnecessary external environment pollution and personal injury, etc. , ensure the safe operation of pipeline. Forged steel flange pneumatic valve parameters: nominal diameter: DN15 ( 1/2 ') ~DN1400（ 56 '). Pressure range: ANSI Class150 ~ 2500, PN16 ~ 420 working temperature: - 29℃（ - 20°F） ~+425℃（ 797°F） Operation mode: handles, gear, pneumatic, electric and hydraulic installation: installed in horizontal or vertical forged steel flange pneumatic valve technical features: (1) the body USES the whole forging, ensure no trachoma, cracks and other quality problems. (2) has excellent corrosion resistance. (3) double block and the emission function, upstream and downstream side of the seat is a fluid blocking, body lumen retentate through the discharge valve. (4) structure of fire safety. (5) quick convenient switch, compact structure, light weight, small size height direction. 6. Pneumatic shape closed parts can automatically locate the boundary position, can withstand the closing high pressure difference, in the full open and full closed, aerodynamic body and seat sealing surface and the dielectric isolation. Cruelly forged steel flange pneumatic valve is 90 ° rotation movement, pneumatic passed by circular hole axis, full size of the air cavity in the body for medium straight flow channel, offers very little resistance. End of valve end can add sleeves. Can use buried pet-name ruby, stem extensions according to the needs of engineering, and the corresponding greasing, sewage, and emptying device by tube extends to the ground. Forged steel flange pneumatic valve scope of application: forged steel flange pneumatic valve is suitable for chemical, oil, natural gas, metallurgical and other industries and medium containing hydrogen sulfide, too many impurities, severe corrosion of gas pipeline. Pneumatic valve working principle: high pressure forged steel forging steel main characteristics pneumatic valve type O cut off the working principle of the pneumatic valve
