Technical parameters of water butterfly valve Elephant WBV1632E-2W-Fb-H

Electric quarter-turn actuators Elephant QT2-N-xEM-O1-x-U1 with thermal protection and heater are designed for remote and local control of shut-off pipeline valves with a quarter-turn shut-off element

The positioner uses a nozzle-flap type device and a feedback servomechanism (a system of springs and levers) to balance the control and feedback forces when the pneumatic actuator (valve) reaches the position corresponding to the control signal

Porte WBV3232E-2W-Fb PA-SA APL-510N-EX

Operating principle: The valves are opened and closed by turning the disk by 90°
