VG7443NT+72CHGC

The VG7443NT+72CHGC from Johnson Controls is categorized as a bronze globe valve, designed to operate efficiently in different temperature and humidity ranges. This valve utilizes an actuator model VA7820-HGC-2 for smooth regulation of flow. It is rated at 24 VAC, with an acceptable voltage variation from 19 to 30 VAC, thus ensuring compatibility in multiple installations.

Maintaining a NEMA 2 (IP54) rating, this unit can withstand moderate dust and water exposure, making it suitable for various operational settings. The valve is engineered for operation in temperatures ranging from 2°C to a maximum of 170°C, ensuring versatility in different applications, including heating and cooling systems.

For storage, it can handle temperatures between -40°C and 80°C, allowing flexibility in handling and maintenance. The humidity tolerance of 10% to 90% RH (non-condensing) adds to its suitability for various indoor applications. Rated at 11 VA transformer sizing, this valve provides reliable power management as part of its operation.

The VG7443NT+72CHGC features a proportional control type with a spring return stem-up mechanism along with two auxiliary switches for additional functionality. Its flow coefficient is rated at 11.6 Cv, equating to 10.0 Kv, which indicates significant flow capacity. Furthermore, the valve establishes robust connections through NPT (threaded) end connections. Constructed from cast bronze for the body and 300 series stainless steel for internal trim, it assures durability and reliability in demanding environments, making it suitable for various piping systems.
