Product [pneumatic butterfly valve (regulating valve / switch type), (to clamp type, flange type)：

Product model：SMD type

Product Name: pneumatic butterfly valve (regulating valve / switch type), (for clamp type, flange type)

Product features: the company produces pneumatic butterfly valve, is the introduction of foreign advanced technology on the basis of special design, carefully manufactured products. Butterfly valve with travel limit switch, solenoid valve, triple pieces and 0.4-0.7MPa gas source can switch operation, and send out two pairs of passive contact signal indicating valve switch. The use of intelligent control and positioning, and supporting domestic electric valve positioner, input 4-20mADC signal and 0.4-0.7MPa source can realize intelligent control, realize the adjustment of the parameters of pressure, flow, temperature, liquid level etc.. The utility model is driven by compressed air, and the valve rod drives the valve core to rotate 90 DEG C in the valve body, so that the fully open fully closed action can be realized. 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 tightness, easy maintenance, convenient installation, strong adaptability, etc.. Can be widely used in petroleum, chemical, light industry, pharmaceutical, paper, automobile and other industrial automatic control system for remote centralized control or local control.
