The VG7842CT+72CHGA from the Johnson Controls VG7000 series is a compact and efficient bronze control valve equipped with an electric actuator. With a 1/2 inch (DN15) valve size, this unit is specifically crafted for a three-way mixing configuration. Weighing 7.2 lbs, it integrates easily into multiple systems requiring precise fluid regulation.
Constructed from cast bronze, the valve features internal brass trim, which facilitates a linear flow characteristic. The flow coefficient stands at 0.73 Cv, indicating its effective performance under various working conditions. Featuring threaded NPT end connections, the VG7842CT+72CHGA ensures secure fittings in line with standard piping configurations.
The installed actuator model, VA7820-HGA-2, operates on a control signal dictated by floating/proportional inputs, providing flexibility in operational demands. This actuator requires a voltage rating of 24 VAC and can accommodate input frequencies of 50 to 60 Hz. Its actuator torque is rated at 180 lb-in, supporting reliable operation in valve actuation. Additionally, it can handle a maximum closeoff pressure of 345 psig (2377 kPa), making it capable of thriving in higher-pressure applications. The valve is also rated to an enclosure standard of IP54, which provides adequate protection against dust and moisture ingress for longevity and dependability in various environments.
