Model: SMD-type
Product Name: pneumatic valve （control valve / switch type）, （wafer type, flange type）
Features: the company that produced precision pneumatic butterfly valve, is the introduction of foreign advanced technology, based on specially designed, well-made ??products. Butterfly with a travel limit switch, solenoid valve, FRL, and 0.4-0.7MPa gas source switching operation can be realized, and sent two pairs of passive contact signal indicating valve switch. The use of inligent control and positioning, and supporting domestic electric valve positioner, input 4-20mADC signal and 0.4-0.7MPa gas source to achieve inligent control, to realize the pressure, flow, temperature, level and other parameters of the adjustment. It is a compressed air powered, driven spool valve stem in the valve body rotation 90 ℃, can fully open – fully closed the action. Sealing performance of the product into its metal sealing and soft sealing. With a compact, compact, reliable operation, good sealing, easy maintenance, easy installation, flexibility and other advantages. Can be widely used in petroleum, chemical industry, light industry, pharmaceuticals, paper, automotive and other industrial automatic control system for centralized remote control or local control.
