DN15-DN50 G1/2"-2" bsp 2 way or 3 way proportional flow control valve for HVAC system

DN15-DN50 G1/2"-2" bsp 2 way or 3 way 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.

 Adjustable flow ratio, high reliability, high life, the use of graphite reinforced PTFE valve seals, valve stem seals double EPDM. Built-one assignment butterfly, afraid of reverse pressure. Equal percentage flow characteristic. High Off strength 1.4MPa. Rated working pressure PN40. Maximum working pressure 0.35Mpa. With manual actuator shorted button. -5 To 121 ° C operating temperature. Suitable for central air-conditioning, heating system, hot and cold water, steam humidification.

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.
