WVA4

Description 

Winner control ball valve consists of WAV4-… series rotary actuator and WCBS… series ball valve. Equal percentage flow characteristic guarantees the valve performances of stability.

Winvall electric 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

Winner control ball valve is motor-operated by a type of WVA4-1…, WAV4-2…, and WAV4-3… actuator. The actuator is controlled by a modulating on/off , 3-point or proportional control system and move the ball of the valve, to the opening position dictated by the control signal.

Function （3-point,or proportional type）

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

WVA4-1…   230 VAC±15%, 3-point

Brown wire is power on                                                                counterclockwise rotation, valve open

Red wire is power on                                                                    clockwise rotation, valve close

Brown or red wire is power off                                                     Valve keep the current position

WVA4-2…   24VAC/DC±15%, 3-point

Brown wire is power on                                                                counterclockwise rotation, valve open

Red wire is power on                                                                    clockwise rotation, valve close

Brown or red wire is power off                                                     Valve keep the current position

WVA4-2…-2   12VDC, 3-point

Brown wire is power on                                                                counterclockwise rotation, valve open

Red wire is power on                                                                    clockwise rotation, valve close

Brown or red wire is power off                                                     Valve keep the current position

WVA4-3…   24VAC/DC±15%, proportional (0-10VDC/0-20mA, 2-10VDC/4-20mA)

Black wire and brown wire are the power wire.

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

WVA4-3…-2   12VDC, proportional (0-10VDC/0-20mA, 2-10VDC/4-20mA)

Black wire and brown wire are the power wire.

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

WVA4-3… Flow characteristic

Input 0-10VDC control signal

Flow characteristic: equal percentage

Flow range: 0%-100%   

Connector

Installation: 

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"
