Forged steel main characteristics pneumatic valve valve industry _ pneumatic components factory

Pneumatic pneumatic valve forged steel pneumatic valve overview: forged steel pneumatic valve is designed according to API 6 d, GB/T12237 production valve, the valve is suitable for Calss150 ~ 2500 lb, various piping PN16 ~ 250. Forged steel pneumatic valve main characteristics: 1, the fluid resistance is small, the resistance coefficient with section of equal length. 2, have fire prevention, anti-static, stem fly out of function, such as simple structure, small volume as a whole. 3, reliable seal, soft seal pneumatic valve sealing surface material widely used ptfe, hard seal using a spray of tungsten carbide, sealed performance is good, the pipeline of oil, natural gas medium is widely used in the system. 4, convenient operation, opening and closing rapidly, from open to close just rotate 90 °, is advantageous for the remote control. 5, convenient maintenance, pneumatic valve has simple structure, the seat ring is active, remove the replacement is more convenient. 6, in the full open or full close, aerodynamic body and seat sealing surface and the dielectric isolation, medium through does not cause the valve sealing surface erosion. High pressure forged steel 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 pneumatic from design, material selection, manufacturing, test, surface handling and paint are strictly in accordance with the corrosion engineers NACE standard requirements. This series of pneumatic valve material widely, and internal parts materials are not only using the surface plating nickel material 316, sealing ring using a special polymer materials. Make the 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 valve selection. Forged steel pneumatic valve main functions: (1) the valve lumen stagnation abnormal pressure due to temperature changes, the medium of medium pressure to push the seat from the aerodynamic body, achieve the result of automatic relief, relief valve seat after automatic reset. (2) in addition to general seating, set sealing structure in particular, can play because of the sealing ring damage when leak emergency rescue action. (3) when fire or different temperature to soften seat sealing loss or when. Valve operation is still reliable, at the same time, the seat and aerodynamic body form metal to metal, to temporarily seal effect, to stop the fire to further expand, comply with the provisions of the AP16FA. (4) unscrew out device can check whether the valve seat leakage occurs, can discharge midplane retentate to valve's unilateral medium to reduce pollution. In working status, when the valve is in full open or close, can replace the valve stem packing. (5) stem parts adopt PTFE packing and double sealing o-ring, especially suitable for the gas medium. Stem movement parts adopt high quality SF, self-lubricating bearings, make smaller friction coefficient, reduce operating torque. : all welded high pressure pneumatic pneumatic y-shaped three-way solenoid valve structure _ electric y-shaped three-way pneumatic valve
