2-way Stepper Motor Water Flow Electric Control Ball Valve for Fcu System

2-way stepper motor ball valve for fcu system

Description

m otorized ball valve consists of on/off type or 3-point type actuator and W 6 BV… series ball valve,which have compact structure, stable operation, excellent capacity of water stoppage, large water flow rate, zero dirt block and low torque. motorized ball valves are widely used in HVAC system, heating system, water treatment system and some industrial equipment.

Application

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

Operational mode

motorized ball valve is motor-operated by a type of WRA-5320, and WRA-5320A 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.

Function ( 3-point or on/off type )

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

WRA- 5 3 20 3-point type

Blue wire is power on Valve closed

Brown wire is power on Valve open

Blue or brown wire is power off Valve keep the current position

Black wire is connected to the null wire. Also can be used as on/off type.

WRA- 5320 A on/off type

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

Brown wire is connected to the power wire.

Blue wire is connected to the com. Only can be used as on/off type.

I nstallation

IInsert the valve stem to the bottom of the actuator, and insert 2 pin, located in the bottom of the actuator to the valve’s mounting hole. Then screw down the brass cap nut
