The Johnson Controls VG7443GT+821E01 is a two-way globe control valve crafted from resilient cast bronze. It is outfitted with stainless steel trim, providing enhanced durability while maintaining performance. This valve has a nominal size of 1/2 inches and weighs 13.0 lbs. The actuator allows for a stroke adjustment ranging from 5/16 of an inch to 1 inch, accommodating varying flow requirements.

During operation, this control valve exhibits an equal percentage flow characteristic, which ensures effective modulation of fluid dynamics. It operates within a wide fluid temperature range of 2°C to 170°C, making it suitable for diverse industrial applications.

This unit operates with a maximum closeoff pressure of 76 psig (524 kPa) and has a spring range that completes its functional requirements between 9 to 13 psig. Leakage is minimal, measured at only 0.01% of the maximum flow when utilizing brass trim. Threaded NPT end connections simplify installation, while the actuator housing features a sleek black finish and the valve body is visually identifiable in bronze. The control mechanism is pneumatic, set up with an MP82 actuator model that includes a factory-mounted V-9502 positioner, ensuring precise position control thanks to its effective diaphragm area of 25 square inches. This robust design guarantees reliability and operational efficiency for a variety of flow regulation tasks.
