High pressure forged steel ball pneumatic valve

high pressure forged steel ball pneumatic valve is according to the needs of users, in order to meet under the environment of sulfide sulfide application cracking requirements, this series high pressure forged steel ball from design, material selection, manufacturing, test, surface handling and paint are strictly in accordance with the corrosion engineers NACE standard requirements. This series pneumatic ball valve not only material widely, and internal parts materials are implemented in superficial nickel plating material, sealing ring using special polymer materials. Pneumatic valve not only corrosion resistance, resistance to sulfide ability strong, fire prevention, anti-static, good seal performance, working pressure and temperature range is wide, full size and reducing all ready, and can match a variety of device drivers, is a chemical, oil refining, ju gas mining and conveying system ideal with pneumatic valve selection.
high pressure forged steel ball pneumatic valve main functions:
high pressure forged steel ball pneumatic valve lumen stagnant medium due to the temperature change and often booster, the medium pressure promote pneumatic valve seat from the ball, achieve the result of automatic relief, relief pneumatic seat after automatic reset. Pneumatic in addition to general seating, set sealing structure in particular, can play because of the sealing ring damage when leak emergency rescue action. When fire or different pneumatic seat sealing temperature burning or softening. Pneumatic valve is still reliable operation, and at the same time, the pneumatic valve seat and metal to metal sphere formation, to temporarily seal effect, to stop the fire to further expand, comply with the provisions of the APFA. Unscrew out device can check whether the pneumatic valve seat leakage, can also be emissions midplane retentate to pneumatic valve's unilateral medium to reduce pollution. In working status, pneumatic valve is in full open or close, can replace the pneumatic valve stem packing. Pneumatic valve rod parts sealed using PTFE packing and double sealing o-ring, especially suitable for the gas medium. Pneumatic valve rod movement parts adopt high quality SF, self-lubricating bearings, make smaller friction coefficient, reduce operating torque.
