The Honeywell V5011N1073 Precision Direct Tension Control valve has a 1 1/4-inch body and is designed to provide precise and proportional fluid flow control in HVAC systems. This valve, which has an 18.7 Cv and an equal % flow characteristic, is frequently employed in HVAC applications where precise fluid flow control is essential. The best possible control over temperature and pressure is made possible by the PDTC function, which guarantees accurate modulation in response to variations in control signals. Installed in a variety of HVAC equipment, including heating systems and air handling units, the V5011N1073 enhances the system's overall performance and energy efficiency by facilitating controlled and efficient fluid flow. It also helps HVAC systems maintain stable pressure and temperature levels.
