Electric Actuated Wafer Butterfly Valve
Electric actuated wafer butterfly valve; a wafer-type butterfly valve clamped between two flanges with bolts, with an electric motor actuator with ISO 5211 connection mounted on top, remotely controlled via electrical signal. Ideal for automation in facilities without compressed air systems, in field and remote applications.
Actuators operate on-off with proportional control option available (4–20 mA / 0–10 V). Supplied with 220 V AC, 24 V AC and 24 V DC power options, IP67 protection class and 90° ±5 rotation angle; in case of power loss, the valve can be controlled manually via lever or handwheel. Available from DN25 to DN600; with stainless steel, nickel-plated or bronze disc and EPDM, NBR, Viton or PTFE seat options.
