DQF-F*DQQ-E2 Motorised Ball Valve
Easy Installation/Security Assurance/One Year After-sale Guarantee/Provide Technical Guidance
(PDF)Motorised ball valves are available for terminal waterway control . Thermostat control the motorised ball valve actuator,and the actuator motor drive the valve ON/OFF to make the medium flow or disconnected, and the fan coil blow at the same time to control the temperature automaticly.
