Operation

Open/Close Duty :
Water flow can controlled automatically according to operating order to
get complete open or close certain percent.

Modulating Duty :
To Get :
- Constant flow rate in pipes.
- constant water pressure in pipes.

Integral with matic unit
Technical Aspects :
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 the motion from the motor to the valve through worm gear box principle which provide self lubricant and locking.
The Actuator casing is made of cast iron (GG25) accord. to international specification to be able withstand the operation mechanical stresses.
