Applications of Electric Butterfly Valve

Water supply planets (industrial and potable water), wastewater systems.
Air supply plants.
Pressure and plants.
Water supply plants, well chambers, pumping stations, high-level reservoirs, filter plant, and lines.
Power stations, primary and secondary cooling circuits.
Waste water disposal, high water pumping stations, water engines, and clarification plants.
Water, non-aromatic hydrocarbons, weak alkalis, and weak acids.

Technical Aspects of Electric Butterfly Valve:

The Actuator is equipped with two independent adjustable limit switches and two torque switches without any plastic parts or batteries, which may need maintenance.
Connecting wires are sealed in the switch housing actuator. Switches work under mechanical principles.
The Actuator includes a hand wheel marked with two arrows for open/close in case of power failure and adjustment mode.
The hand wheel will automatically be disengaged when the electric motor is energized.
The Actuator transmits motion from the motor to the valve through a worm gear box principle, which provides self-lubrication and locking.
The Actuator casing is made of cast iron (GG25) according to international specifications to withstand the mechanical stresses of operation.
