The VG7241GT+71CHGA valve, part of the VG7000 Series by Johnson Controls, represents a high-quality choice for applications requiring precise fluid control. This component is constructed from durable cast bronze, designed for longevity and resistance to wear.
As a two-way control valve, it maintains a normally open configuration, allowing for efficient operation that can be closed with a push action. Spanning 1/2-inch in size, this valve is well-suited for multiple installation scenarios, particularly when paired with its NPT threaded connections. The valve ensures a reliable flow regulation performance, credited to its brass trim and equal percentage flow characteristics.
The control port Cv rating of 4.6 highlights its capability to manage moderate flow rates efficiently. Powering the VG7241GT+71CHGA is the VA7810-HGA-2 actuator, which operates on a 24 VAC input and utilizes proportional control for refined modulation. This non-spring-return actuator allows for precise adjustments in flow according to system demands.
With a maximum allowable close-off pressure of 345 psig, this valve is designed to function effectively even under significant pressure scenarios. Additionally, it offers a temperature operating range, functioning reliably from a minimum of 2 °C to a maximum of 65 °C. The rangeability exceeds 25:1, providing versatility in flow control applications, and the brass seat with a molded elastomeric disk enhances sealing capabilities.
