The VG1845ERH938GGC is a ball valve equipped with a spring-return electric actuator, part of the VG1000 Series from Johnson Controls. This unit is designed specifically for three-way mixing, providing flexibility in flow control. Crafted from forged brass, the valve ensures reliable performance in various applications. The valve's size measures at 1-1/2 inches, and it connects through NPT threaded ends for solid installation.
It can withstand a maximum closeoff pressure of 200 psig, making it suitable for high-pressure systems. Stainless steel trim enhances the valve's flow characteristics, offering an equal percentage flow profile. Additionally, the control port Cv is rated at 29.2, facilitating effective flow management.
The actuator used is the VA9208-GGC-3 model, which operates on an actuator voltage rating of 24 VAC. This electric actuator provides proportional modulating operational control. For added functionality, the valve includes two auxiliary switches that can be used for monitoring and control purposes.
In terms of operational temperature, the VG1845ERH938GGC is versatile, handling fluid temperatures ranging from -30 to 140 °C. The valve itself can operate in environments with a minimum temperature of -40 °C and a maximum of 60 °C. This broad temperature range makes it valuable for use in various conditions, enhancing its adaptability across different systems.
