Description
Butterfly valve WBV1413E-2W-Fb QT-N-EM-A1-220VAC-U1 is designed for installation on pipelines in automatic control systems of heat and water supply, in stationary air conditioning and ventilation systems at industrial and civil facilities.
Operating mode of the gate with electric actuator is repeated-short-time S2 according with the duration of switching on (SP) of 15%. The electric actuator is powered by 50 Hz AC mains.
Quarter-turn actuators are designed for remote and local control of 0° ~ 270° rotation of a shut-off valve of such types as ball valve, etc. The actuators are mounted directly on pipeline valves. The mounting dimensions are in accordance with the international standard ISO 05211 / DIN3337. Four microswitches are used to limit the output shaft travel to the end positions of the valve actuator.
