The Johnson Controls VG7441ET+72CHGA is a robust bronze control valve, designed specifically for demanding flow regulation tasks. It measures 1/2 inch in size and employs a body type that is two-way and normally closed, activating with a push-down-to-open action. Minimizing leakage concerns, this valve ensures performance with a leakage specification of only 0.01% of maximum flow, making it reliable for precision applications.
Equipped with a Cv rating of 1.8, this control valve features brass trim that promotes equal percentage flow characteristics, contributing to effective fluid handling. Integration is straightforward thanks to NPT threaded end connections, allowing for seamless incorporation into existing systems. The VG7441ET+72CHGA includes a spring-return mechanism in its electric actuator, specifically the VA7820-HGx-2 model, which provides responsive operation and control.
This unit is powered at 24 VAC and operates within a proportional control scheme, accepting a control signal in the range of 0 to 10 VDC. Feedback capabilities are integrated to facilitate accurate monitoring and adjustment during operation. The valve is competent across a temperature range of 2°C to 65°C, accommodating diverse environmental conditions while maintaining reliable performance.
