Product Detail

Model No.: WRA3-202S
Packing: Carton
Means of Transport: Ocean,Land,Air
Name:: Modulating Proportional

Electric Motorized Ball Valves

WRA3-...S series fast running control ball valve consists of  stepping motor actuator and W8BV... series ball valve. Equal percentage flow characteristic guarantees the valve performances of stability.,Stepping motor control ball valve  It has the characteristics of accurate, rapid, strong anti disturbance, is a typical digital control mode, and the traditional analog control is the essential difference between. Easily extended to the digital network transmission RS485 MODBUS. It is 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.

 

Application

HVAC system 

Heating system

Water treatment system

Industrial equipments

 

Operational mode

WRA3-S series actuator control ball valve is operated by stepper motor. The actuator is controlled by a modulating, on/off , 3-piont or proportional control system,to controlled valve body. Standard product is proportional control or switch / floating-point type, can be customized according to customer requirements quickly of proportion type,  or quickly of on/off type, or quickly of  floating-point control product.
