Description Fast running control ball valve consists of WRA3-...S series stepping motor actuator 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 accurate,fast,strong anti-interference. It is a typical digital control mode.
Application HVAC system Heating system Water treatment system Industrial equipment
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-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.
