• Integral flow measurement technology
• GPM gauge for reading flow
• Hand wheel for setting flow
• Positive shutoff

This 3/4 inch calibrated flow measurement and balancing valve monitors system flow in low to medium flow rate HVAC units, providing highly accurate flow measurement and adjustment. It consists of a brass and polyamide body with F-NPT connections, integral patented technology that allows the reading and setting of flow rate without the need for instrumentation or tools. It is equipped with a GPM gauge to read flow and a hand wheel to set and lock the flow setting. Its ball valve construction allows full shut-off capability and is ideal in hot/chilled water units such as fan coil units, water source heat pumps, reheat coils, panel coils, small branch lines, unit heaters, unit ventilators, finned radiation and convectors.
