Designed for precise applications, the Johnson Controls VG1845FSH928GGA is a 3-way control valve equipped with an electric actuator. This unit operates at a size of 2 inches and features NPT threaded connections for easy installation. The valve body is forged from brass, ensuring durability, while the stainless steel trim (ball and stem) contributes to its reliability.
The actuator is identified as a VA9208-GGA-2 and is configured with a spring return mechanism that opens Port A. The valve supports proportional control with input options of either 0(2) to 10 Volts DC or 0(4) to 20 mA, making it adaptable for various control systems. It is powered by a 24 VAC voltage rating and provides position feedback within the range of 0(2) to 10 Volts DC.
When it comes to performance, the VG1845FSH928GGA showcases a close-off pressure of 50 PSID and can manage fluid temperatures spanning -30°C to 140°C. The valve has a high rangeability, rated at greater than 500:1, enabling it to efficiently handle varying flow conditions. Electrical connections are facilitated through a 48-inch long, 18 AWG appliance cable.
Further enhancing its reliability, this valve uses seats composed of 15% graphite-reinforced PTFE material, while leakage is minimized to just 0.01% of the maximum flow per ANSI/FCI 70-2, Class 4 standards. Altogether, the VG1845FSH928GGA is engineered for effective control in demanding environments.
