Key specifications
Operating voltage: 230V
Torque: 10Nm
Running time: 140 seconds
Compatibility: 3-way and 4-way valves
How to use
Installation should be performed by a qualified technician to ensure proper electrical connection and mechanical alignment with the valve. The actuator is mounted directly onto the valve body, following the manufacturer's guidelines for secure attachment. Once installed, the electrical wiring must be connected to the control system according to the provided wiring diagram. After installation, a test cycle should be performed to verify that the actuator moves the valve through its full range of motion correctly.
What to consider before purchase
Verify that your existing valve is a 3-way or 4-way model compatible with this actuator.
Ensure that the 230V power supply is available at the installation point.
Check if the 10Nm torque rating is sufficient for the specific valve size and pressure conditions of your system.
Usage recommendations
Regularly inspect the actuator and valve connection during routine HVAC maintenance to ensure there is no debris or mechanical obstruction that could impede the 140-second travel time. Ensure that the electrical connections remain dry and secure to prevent operational faults.
