Brief introduction of Wafer Pneumatic Butterfly Valve
Structure composition:
Pneumatic butterfly valve equipped with travel limit switch, solenoid valve, triplet and 0.4-0.7mpa gas source can realize switching operation, and send two pairs of passive contact signals to indicate the valve switch.
When adopting intelligent control and positioning, it can be matched with domestic electric valve positioner, input 4-20madc signal and 0.4-0.7mpa air source to realize intelligent control, and realize the adjustment of pressure, flow, temperature, liquid level and other parameters.
Function:
It is driven by compressed air, and the valve stem drives the valve core to rotate 90 ℃ in the valve body, which can realize the action of full opening and full closing. The product is divided into metal seal and soft seal according to its sealing performance. The utility model has the advantages of compact structure, small volume, reliable operation, good sealing, easy maintenance, convenient installation, strong adaptability, etc.
Application:
It can be widely used in petroleum, chemical, light industry, pharmaceutical, paper, automobile and other industrial automatic control systems for remote centralized control or local control.
