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.
