Elaborated under the condition of pneumatic valve can be used in does not affect the manual for the time being. Pneumatic valve connection methods mainly include: flange and circular plate; The seal types mainly include: rubber seal and metal seal. Through the power signal butterfly valve control switch. This product can be used as a cut-off valve in the pipe system, control valve and check valve. Use the manual control device, in the event of power failure, it can be used without affecting the situation on the manual for the time being. Features: 1, with double eccentric structure, is closed for tight sealing function, sealed performance is stable. 2, sealed vice matching material for stainless steel and the nitrile rubber, using a long time. 3, rubber sealing ring can be located in the body or on butterfly plate, can be used for the different characteristics of media, for the user to choose from. 4, the butterfly plate adopts frame structure, high strength, large flow area, small flow resistance. 5, the whole paint can prevent rust, and as long as the replacement seal seat sealing material, can be used in different medium. 6, valves have two-way sealing function, not controlled by the flow direction of medium, when installation is not affected by spatial location. 7, small volume, light weight, stable performance, simple matching, large flow, the cleaner is suitable for liquid and gas media. Working principles: power supply usually have: AC220V, AC380V, etc. The input signal: 4 - 20mA、0- 10 v, such as the weak current signal. After adjust pneumatic valves and valve stem, pneumatic valve plate can be driven by electricity as a driving force.
