Description
Fast running control ball valve consists of WRA3-...S series stepping motor actuator(stepping motor is made in
Japan) and W8BV... series ball valve. Equal percentage flow characteristic guarantees the valve performances of stability. Stepping motor control ball valve. The characteristic of it is accurat,fast and high efficiency,strong anti-interference. It is a typical digital control mode.
Application
HVAC system
Heating system
Water treatment system
Industrial equipments
Operational mode
Winner control ball valve is motor-operated by a type of WRA3-S series actuator. The actuator is controlled
by a modulating on/off , 3-piont 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 (Running time can be setted between 8 secs to 120 secs) dc switch, proportion,floating control products.
