The VG7441LT+72CHGA is a reliable control valve from the VG7000 series manufactured by Johnson Controls. Specifically engineered as a 2-way bronze control valve, it excels in a range of applications. The valve is configured to be normally closed with a push-down-to-open mechanism, facilitating operational flexibility in fluid management.
At a valve size of 3/4 inches, this unit provides a flow coefficient of 7.3 Cv (6.3 Kv), ensuring effective flow regulation. The threaded NPT end connections simplify installation and integration into existing systems. This model features brass trim, which contributes to its durability and functionality.
Powering the valve is an actuator designated VA7820-HGA-2, which operates effectively under a proportional control signal. It operates at a voltage rating of 24 VAC, giving it ample compatibility with various control systems. The actuator is designed to exert a stem force of at least 180 lb, providing the necessary force for valve operation.
The VG7441LT+72CHGA can perform within a temperature spectrum of 2 to 65°C for general operation. It is well-suited for fluid applications with water temperatures up to 140°C and can handle saturated steam at pressures of 38 psig. The valve meets ANSI B16.15 Class 250 standards ensuring its robustness in service. Additionally, it boasts a leakage class of 0.01% of maximum flow, combined with an impressive rangeability exceeding 100:1, making it a versatile choice for complex fluid control systems.
