Description

1.Fast running control ball valve consists of WRA3-...S series stepping motor actuator(stepping motor is made in Japan) and W8BV... series ball valve.

2.Equal percentage flow characteristic guarantees the valve performances of stability. Stepping motor control ball valve. The characteristic of it is accurate,fast and high efficiency,strong anti-interference. It is a typical digital control mode.

3.It has obvious advantages in such industrial equipments,which requires fast and accurate control. And it is widelyused 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 flowregulation and on/off control.
