MOTORIZED VALVE

This listing includes 1 unit of motorized valve 2 way, DN25(1" BSP)

MODULATING: 0-10V (proportional)

POWR VOLTAGE: 24VAC/DC

Application:

Equal percentage flow characteristic guarantees the valve performances of stability. Control ball valves are widely used in HVAC system, heating system, water treatment equipment, and water running control in industrial automation, such as: AHU, flesh air-handling unit, differential pressure control unit and heat exchanger for flow regulation and on/off control.

Operational mode

this control ball valve is motor-operated by the actuator. The actuator is controlled by proportional control system and move the ball of the valve, to the opening position dictated by the control signal.

Output torque: 4N.m     Angle of rotation: 90°

Manual handle  

Automatic overload protection system

Manual selection of ball rotation direction: C.W. /C.C.W, factory setting is C.W.

Protect rank: IP54

Function (proportional type)

The actuator is controlled by a modulating on/off, 3-piont, and proportional control signal, using high transmitting ratio gear drive to fix and lock.

Black wire and brown wire are the power wire.

Yellow wire accept 0-10V control signal to control the valve’s open angle.

Flow characteristic

     Input 0-10VDC control signal

Flow characteristic: equal percentage

Flow range: 0%-100% 

IIInstallation:

  1. Ensure that the valve body is in the full open status.

  2. Ensure that the actuator is in the fully open position as the follow picture:

3. Aligning the valve stem, press down the aluminum alloy spindle.

Change of running direction

The rotation can be reversed by pushing the CCW/CW switch on the casing.

Factory settings: "CW"
