Description
Rotary disc gate 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 actuator with spring return is designed for safe control of valves or dampers in case of power supply voltage loss. They are used in various industries. Principle of operation: this actuator is applicable in short-term mode S2 with the duration of switching on 20 minutes. The actuators are powered from the AC mains 220V 50Hz 1 phase. When the actuator is energised, the valve shut-off valve is set in motion and the spring is compressed. When the power supply is switched off, the spring is unclamped, actuating the actuator and ensuring return of the valve shut-off body to the initial position (full opening or full closing).
