What are the common operating forms of electric smoke exhaust fire valve

1.Operation method of electric smoke exhaust fire valve: the actuator acts in the opening or closing direction of the valve according to the opening or closing of the switch signal.

If the on/off signal is maintained, the actuator will continue to operate until it reaches the position where the valve is fully open or closed and automatically stops. No matter where the actuator is moving, as long as the state of the switch signal changes (from on to off or from off to on), the actuator will move in the opposite direction.

2.current input form: if your input is DC 4-20mA current, then choose this form. Operation method: actuator according to the size of the input current signal, can drive the stem to walk and stay in any direction of the full stroke, and then complete the arbitrary adjustment of the valve opening.

3.voltage input form: if your input is DC 0-10V or 2-10V voltage, choose this form. Operation method: actuator according to the size of the input voltage signal, can drive the stem to walk and stay in any direction of the full stroke, and then complete the arbitrary adjustment of the valve opening.
