The Johnson Controls VG7241GT+72CHGA serves as a robust component in industrial fluid control systems. This bronze control valve showcases a construction of cast bronze and features a two-way body type that operates in a normally open manner, closing with a simple push action. The valve measures 1/2-inch in size and achieves a flow coefficient of 4.6 Cv (4.0 Kv).
With threaded NPT end connections, installation is straightforward. The valve's trim consists of brass, designed for equal percentage flow control, which supports the precise regulation of fluid dynamics. Its standard threaded stem allows for reliable operation, especially when paired with the VA7820-HGA-2 spring-return electric actuator designed for stem-up configurations.
This actuator operates at an AC voltage rating of 24 VAC and employs a proportional control type within a range of 0 to 10 volts DC. For flexibility in applications, it can be field-selected for either on/off or floating control methods. The VG7241GT+72CHGA is built to handle a maximum closeoff pressure of 345 psig, ensuring safe usage in various system pressures. Designed for operational temperatures between 2°C and 65°C, this valve remains effective for water applications up to 140°C and can manage up to 38 psig of saturated steam, making it a reliable choice for demanding conditions.
