O cut the working principle of the pneumatic valve valve industry _ pneumatic components factory

Pneumatic valve type O cut the working principle of the pneumatic valve, pneumatic components factory valve industry production type O cut pneumatic valve as full size floating pneumatic pneumatic valve, flange has a compact structure, large rated flow coefficient, good cutting, switch quickly, etc. O cut pneumatic valve technology parameters: pressure rating: PN1. 0 to 6. 4 mpa range: DN15 ~ 500 mm suitable medium temperature: soft seal - 40 ℃ ~ + 180 ℃, hard seal 196 ℃ ~ + 450 ℃ leakage level: soft seal of VI, metal sealing V O cut pneumatic valve features: (1) seal edge sealing technology, adopt unique elastic lip ensures zero leakage of the cutting requirements (2) pneumatic core after surface hardening treatment after the special craft, after grinding, polishing, smooth wear-resisting, optical mirror effect. (3) built in stem structure, to ensure the valve stem in use process, do not fly out due to the pressure, has better rigidity and security. (4) O cut pneumatic valve using all-pass straight flow channel of the same as the pipe diameter, zui large flow capacity, zui small flow resistance. 5. Pneumatic core is just around the valve spindle turn 90 ° can be fully open or close, simple quickly. 6 stem seal USES the radial and axial two-way sealing, achieve long-term use without leakage, namely stem seal zero maintenance; Packing can choose PTFE or flexible graphite respectively, for a variety of different media and different temperature conditions. All landowners body structure with high platform, use with ISO5211 standard installation size, with direct docking fastening between cylinder, electric actuators, when the temperature does not exceed 250 ℃, no need to install the bracket and shaft sleeve, simple. End up with AP series double piston gear rack type pneumatic actuators, with compact structure, large output force, and the advantages of action accurate, also can be equipped with various types of electric actuators to control, is widely used in petroleum, chemical, metallurgical, pharmaceutical, textile, paper and other industries of gas, liquid, fluid of spices and cut off the control of low pressure steam. : O type pneumatic valve internal structure of floating type pneumatic valve _ soft seal pneumatic valve Q641F/H/P pneumatic stainless steel pneumatic valve
