The Johnson Controls VG7251PT+3008E is a pneumatic actuator valve with a primary construction of cast bronze. Weighing in at 6.5 lbs, this valve is designed as a two-way unit that maintains a normally open position unless pressure is applied to close. Connecting via union globe or union angle fittings, it integrates seamlessly into existing piping systems.
This valve is sized at 1-1/4 inches, and its brass trim utilizes an equal percentage flow characteristic, ensuring precise control over fluid dynamics. Featuring a control port Cv rating of 18.5, it provides efficient management of flow rates in various applications.
The V-3000-8012 pneumatic actuator is integrated into the design, offering exposed functionality for easy access. This actuator operates within a spring range of 9 to 13 psig, accommodating varying operational needs. The valve maintains a maximum closeoff pressure rating of 26 psig (179 kPa).
It is designed to function effectively within a fluid operating temperature range of 2 °C to 140 °C for water, and it can handle up to 38 psig for saturated steam conditions. The minimum and maximum operating temperature thresholds ensure reliable performance in a variety of settings, and the rangeability exceeds 100:1, adding to its adaptability in different processes. The VG7251PT+3008E is thus well-suited for applications that demand reliable flow regulation and precise control.
