Product features:

This pneumatic butterfly valve, is my factory special design based on the introduction of foreign advanced technology, careful manufacture products. Butterfly valve with a travel limit switch,solenoid valve, triple pieces and 0.4-0.7MPa gas source switching operation can be realized, and sends the switch two on passive contact signal indicating valve. 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, to achieve the regulation of parameters of pressure,flow, temperature, liquid level etc.. It is powered by compressed air, the valve rod drives the valve core to rotate 90 degrees in the valve body, can achieve full - full closure of the action. The product is divided into the metal seal and soft seal by the sealing performance. Has the advantages of compact structure, small volume, precision, reliable operation, good sealing performance, easy to repair, convenient installation, strong adaptability etc. Can be widely used in petroleum, chemical industry, light industry, papermaking, pharmaceutical, automotive and other industrial automatic control centralized remote control or local control system.
