Efficient Quarter-Turn Butterfly Valve

This rotary control valve serves as a versatile fluid control solution, working in tandem with Electric Intelligent Temperature & Flow Control Valve, Pneumatic Triple Eccentric Rubber Lined Control Butterfly and Pneumatic O-port Cut-off & Control Ball Valve to cover full-range flow regulation and shut-off requirements for industrial piping systems. Matched with a valve positioner, the ZAJW butterfly valve delivers precise proportional modulation. Its streamlined valve body creates minimal flow resistance and boasts an outstanding flow coefficient. The partially spherical disc generates nearly equal-percentage flow characteristics, while the custom-designed disc and sealing assembly integrate dual functions of flow regulation and tight fluid cut-off. It is fitted with compact, high-precision actuators that respond sensitively to ON-OFF signals, 4-20mADC or 1~5V DC control signals for proportional operation. Built-in direct angle position indication and feedback modules ens…
