Butterfly valve WBV0232E-2W-Fb-H body - aluminum alloy, disc - stainless steel, seal - EPDM. The butterfly valve is designed for use as shut-off or regulating valves for flow control in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries.
Electric 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.
Operating principle: electric actuators are installed directly on pipeline valves. The mounting dimensions comply with the international standard ISO 05211 / DIN3337. Four microswitches are used to limit the travel of the output shaft to the end positions of the valve actuator. The actuators are designed for operation in nominal short-time mode S2.
