The VG7441GT+72CHGA from Johnson Controls is engineered as a two-way control valve composed of cast bronze. It operates with a normally closed design that requires a push-down action to open, offering reliable control of fluid flow. This valve measures 1/2 inch and is suited for applications where compact design is necessary. The end connections are threaded NPT, ensuring secure integration into piping systems. With a flow coefficient of 4.6 (Kv 4.0), it allows for efficient fluid movement.

A key feature of this model is its spring-return electric actuator, designated as VA7820-HGA-2, which is designed for stem-up operation. This actuator operates at a 24 VAC voltage rating and provides proportional control with a 0-10 volts DC input. The field-selectable configurations allow the actuator to be adjusted for either on/off operation or floating control as needed.

In terms of pressure management, the VG7441GT+72CHGA can handle a maximum closeoff pressure of up to 345 psig, making it suitable for various industrial applications. The valve operates effectively within a fluid temperature range of 2 to 140°C for water and up to 38 psig for saturated steam. Additionally, the valve maintains a minimum operating temperature of 2°C and a maximum limit of 65°C, providing versatility for different environmental conditions.
