Motion System Options for HVAC Gas Valve Actuators
In HVAC systems that provide heat for enclosed spaces, gas and liquid flow must be controlled and metered accurately using sensing and modulating elements such as flow control valves or isolation valves. Some control valves are opened and closed manually at the valve stem, while electronic valves incorporate an actuator to move the stem with control from a motor and drive system. Designers have three motor types to choose from, depending on the application requirements. Here’s a summary of the motion system options:
