2 way or 3 way 4-20ma proportional flow control valve for HVAC system

Description

Equal percentage flow characteristic guarantees the valve performances of stability. Control ball valves are widely used in HVAC system, heating system, water treatment equipment, and water running control in industrial automation, such as: AHU, flesh air-handling unit, differential pressure control unit and heat exchanger for flow regulation and on/off control.

Application

HVAC system

Heating system

Water treatment system

 Industrial equipments

Operational mode

 The actuator is controlled by a modulating on/off , proportional control system and move the ball of the valve, to the opening position dictated by the control signal.
