The VG7243GT+71CHGA model is an electric actuator bronze control valve from the VG7000 Series by Johnson Controls, designed for effective fluid management. This valve features a notable size of 1/2 inch (DN15) and weighs 3.1 lbs, making it suitable for a variety of applications where space and weight constraints are a consideration. Its body configuration is two-way, functioning as normally open with a push-down-to-close mechanism, allowing for a straightforward operational mode.
Threaded NPT end connections provide a reliable method for integration into pipe systems. The flow characteristics of this valve are enhanced by its stainless steel trim, which supports an equal percentage flow pattern, yielding smooth and accurate modulation of flow rates. The flow coefficient of 4.6 Cv signifies its capability to handle significant flows while maintaining control.
The actuator featured in this model is the VA7810-HGA-2, designed as a non-spring return type, offering a consistent response to control signals while requiring 24 VAC power and operating effectively at a frequency of 50/60 Hz. The actuator can exert a minimum force of 180 lb, providing the power necessary for reliable operation even under demanding conditions.
This control valve maintains a maximum closeoff pressure of 283 psig (1950 kPa), ensuring its suitability for high-pressure systems. The operating temperature range extends from 2 to 170°C for water, allowing applications in heating or cooling systems. Additionally, this control valve can manage saturated steam up to 100 psig, extending its usability in industrial environments. The IP54 enclosure rating ensures that this device is protected against dust and splashes of water, making it ideal for various installations.
