Application
Water-side control of air handling unit in ventilations
and air-conditioning plants heating system control
Water-side control in heating plants
Fan coil control
VAV reheat
Product feature:
1.Equal-percentage characteristic
Equal-percentage characteristic of the flow is ensured by the “v” angle ball core valve.
2.Constant flow volume V
Constant flow volume V with various differential pressures of 35…350KPa, because of the
integrated pressure regulator. A valve authority of 1 is attained, regardless of differential pressure
variations across the valve.
