D643W D643W-10 D643W-16 Pneumatic butterfly valve

Overview of D643W D643W-10 D643W-16 Pneumatic butterfly valve

D643W D643W-10 D643W-16 Pneumatic butterfly valveis composed of pneumatic actuator and three-dimensional braided core hard sealing butterfly valve. It can also be called pneumatic flange soft sealing butterfly valve, pneumatic flange hard sealing butterfly valve, pneumatic stainless steel flange butterfly valve, pneumatic cast iron flange butterfly valve, pneumatic ductile iron flange butterfly valve, pneumatic cast steel flange butterfly valve and pneumatic flange butterfly valve with manual, Explosion proof pneumatic flange butterfly valve, pneumatic flange rubber soft seal butterfly valve, etc.

Features of D643W D643W-10 D643W-16 Pneumatic butterfly valve

D643W D643W-10 D643W-16 Pneumatic butterfly valve seat adopts hard seal compatible multi-level structure, exquisite processing and advanced technology. The pneumatic metal seal butterfly valve is matched with the electric valve positioner. The operation can be controlled by inputting 4 ~ 20mADC signal and 0.4 ~ 0.7MPa air source, which can adjust the parameters such as pressure, flow, temperature and liquid level. The pneumatic hard seal butterfly I valve is equipped with travel limit switch, solenoid valve, pressure reducing valve and 0.4-0.7mpa air source to realize switching operation, and send two pairs of passive contact signals to indicate the switching of the valve. Pneumatic hard seal butterfly valve is composed of valve body, butterfly plate, multi-level valve seat, valve stem, transmission mechanism and other main components. It has the advantages of simple structure, small volume and light weight. Therefore, pneumatic metal seal butterfly valve is widely used in pipes with corrosive media such as metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas and water supply and drainage.
