Product description

Description

Winner motorized ball valve consists of on/off type or 3-point type actuator and WSBV… series SS304 ball valve, which have compact structure, stable operation, excellent capacity of water stoppage, large water flow rate, zero dirt block and low torque.

Application

HVAC system, heating system, Water treatment system, Industrial equipment

Operational mode

Winner DC motorized ball valve is motor-operated by a type of WRA-42…, and WRA-42…A actuator. The actuator is controlled by a modulating on/off or 3-point control system and move the ball of the valve, to the opening position dictated by the control signal.

Actuator

WRA-42… DC3/6-12/24V, 3-point

WRA-42…A DC3/6-12/24V, on/off

Output torque: 2N.m Angle of rotation: 90°

Protect rank: IP55/IP54 On/off time: 2-12S

Function （3-point or on/off type）

The actuator is controlled by a modulating on/off or 3-point control signal, using reversible synchronous motor and gear speed reducer drive to fix and lock.

WRA-42… 3-point type

Brown wire is power on Valve open

Black wire is power on Valve close

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

Blue wire is connected to the null wire.

Also can be used as on/off type.

WRA-42…A on/off type

Blue wire is the control wire. Power on: valve open, power off: valve close

Black wire is connected to the com.

Brown wire is connected to the power wire.

Only can be used as on/off type.
