WRA3-...(S)
DC Control Ball Valve
Classification:
Control Ball Valve
Product Description
Fast running motorized control ball valve consists of WRA3-...S series stepping motor electric actuator and W8BV... series brass ball valve. Equal percentage flow characteristic guarantees the valve performances of stability. The characteristic of it is accurate、fast、strong anti-interference. It is a typical digital control mode.
WRA3-..S series electric actuator 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 WRA3-..S series electric actuator control ball valve is motor-operated by a type of WRA3-S ..series 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. The standard product is 0-10VDC proportional control 、 on/off or flowing point but can be customized according to customer requirements quickly dc switch proportion、floating control products.
