>> แจ้งความต้องการสินค้า <<
TF proportional valve consists of TFV4- series rotary actuator and DN15-DN50 brass ball valve. 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 ex-changer for flow regulation and on/off control.
Application
- HVAC system
- Heating system
- Water treatment system
- Industrial equipments
Operational mode
- TF proportional valve is motor-operated by a type of, TFV4-304, TFV4-306 and TFV-310 actuator. The actuator is controlled by a modulating on/off, or proportional control system and move the ball of the valve, to the opening position dictated by the control signal.
