All welded high pressure pneumatic valve valve industry structure _ pneumatic components factory

All welded pneumatic valve all welded high pressure pneumatic valve overview: all welded high pressure pneumatic valve as a control medium flow of opening and closing device, mainly used for Class150 ~ 2500 lb. DN15 ~ 1500, applicable temperature - 60 ℃ ~ 200 ℃ oil fluid pipeline, gas pipeline and large heating equipment, etc. Actuators can be divided into the handle a variety of forms, gear, pneumatic and electric, has two high pressure welding and flange connection way all the design of the pneumatic valve welding, welding technology, product test and product quality have tested the API 6 d and NSI D16. 25 standard, according to API ISO9001 product quality control manual. All welded high pressure pneumatic valve structural characteristics: (1) the valve structure of fixed pneumatic valve, the valve body and end connection body are forgings, avoid the defects of the casting parts may be produced and nondestructive flaw detection, to ensure product quality, the valve has the advantages of beautiful shape, small volume, light weight. (2) of the pneumatic detector tracking detection by advanced computer processing, so the aerodynamic body machining precision is high. (3) the body of the special structure design and welding and relief annealing process, after welding material mechanical performance indexes meet the technical requirements. (4) the seat for the double seal structure design, supporting ring axial floating structure for independence, and the surface chemical nickel plating processing, by spring pressure tight seal, solid particles into the sealing face, can prevent the medium has two-way sealing function. 5. Sealing ring used carbon C - 25% PTFE material, to ensure the safety valve for long-term run zero leakage, under normal conditions of use, quality assurance for 30 years. 6 end pet-name ruby valves have fire prevention, anti-static function, in between valve seat and valve body, valve stem and valve cover plus there are high temperature resistant flexible graphite seal ring, stainless steel spring closely connected with the pneumatic body, prompting electrostatic accumulation of zero. 7 valves have spewed function design, equipped with o-ring to realize double seal, valve stem and valve seat has on the hole, but in case of an emergency, the valve stem and valve seat seal. Pneumatic valve stem and special connection, can make the valve stem not bear radial load, achieving pure torque transmission, thus reducing the valve operating torque. : all welded pneumatic valve _ _ electric welding pneumatic valve pneumatic welding pneumatic valve pneumatic valve _ since all welded filter type welding pneumatic valve
