control ball valve

Descripción del producto

Description: Winner series automatic control ball valves are usually used as economic substitutes of common globe valves, suitable for air handling unit, outside air unit, the system of cooling station differential pressure by-pass, heat exchange station (cool / hot water valve) and system pipeline switching. Its caliber ranges from DN*2 to DN*0 and is usually combined with rotary actuators from 6Nm to *0Nm to become automatic *-point ball valve, automatic proportional ball valve and automatic open/close ball valve in accordance with the locale conditions. Features 1. Equal percentage valve characteristic (*-point control / ***0VDC/ON-OFF). 2. No sudden change of flux at the starting (*-point control / ***0VDC/ON-OFF). 3. Excellent control stability (*-point control / ***0VDC/ON-OFF). 4. The same Kvs value with globe valve of the same size (*-point control / ***0VDC/ON-OFF). 5. No need of caliber decrease of the pipe, switching control ball valve has Max. Kvs value. 6. Characteristic of better system load, better control stability (*-point control / proportional control). 7. Big closing pressure; the elastic floating structure ensuring sealing capacity of the valve.
