The Johnson Controls VG7443ST+823E01 is designed as a 2-way globe valve, constructed from durable bronze for reliability in various applications. With a body weight of 26 lbs, it features a normally closed design that activates through a push-down mechanism, enhancing its operational efficiency. Featuring NPT threaded ends for straightforward connection, this valve is compatible with a wide range of piping systems.
The internal mechanics include a stainless steel trip and an equal percentage flow characteristic, which contributes to effective flow management. The valve has a size of 2 inches and provides flow coefficients of Cv 46.2 and Kv 40.0, indicating significant throughput capabilities. With a standard threaded stem and a limited actuator stroke of 3/4-inch (19 mm), it allows for precise adjustments.
The spring range for this valve is set between 9 to 13 psig (62 to 90 kPa), ensuring reliable control under varying conditions. It also withstands a maximum closeoff pressure of 37 psig (255 kPa), making it suitable for high-pressure applications. The operating temperature range is expansive, functioning effectively from 2°C to 170°C, specifically designed to handle up to 100 psig of saturated steam with the stainless steel trim configuration.
For structural integrity, the valve body meets ANSI B16.15 Class 250 ratings, providing assurance of quality and performance. Packing consists of spring-loaded PTFE and elastomer V-rings to minimize leakage, maintaining a low leakage rate of just 0.05% of the maximum flow. Overall, the VG7443ST+823E01 globe valve presents a reliable solution for various fluid control tasks in industrial settings.
