The ball valve is used as a shut-off valve in heating, water supply, steam, fuel and pneumatic systems with compressed air and neutral gases. Installation of valves of this series is possible in systems transporting liquid and gaseous media (water, oil, oils, steam, air, alcohols, glycol, etc.), non-aggressive to the materials of the valve. The use of ball valves as regulating valves is not allowed.
Electric actuator with spring return is designed for safe control of valves or flaps 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 switching-on time of 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).
