Product Details

0-10v/4-20Ma electric actuator with ball 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
