Johnson Controls VG7243LT+71CHGA Valve Assembly

The Johnson Controls VG7243LT+71CHGA is a 3/4-inch NPT 2-way globe valve assembly designed for high-performance regulation of hot water, chilled water, and saturated steam up to 38 psig. Optimized for HVACR systems, this assembly features a cast bronze body and 300 series stainless steel trim, ensuring corrosion resistance and long-term reliability in demanding hydronic loops. The unit provides an equal percentage flow characteristic with a 7.3 Cv rating, allowing for precise linear control even at low flow rates. This specific model is the direct replacement for VG7243LT+7202G, maintaining footprint and compatibility for seamless field retrofits.

Equipped with a VA7810-HGA-2 non-spring return electric actuator, the assembly supports field-selectable control signals, including 0(2)-10 VDC, 0(4)-20 mA, two-position, or floating control. Operating on 24 VAC power, the actuator delivers a minimum stem force of 180 lb to ensure tight close-off satisfying ANSI Class IV leakage standards. The VG7000 series design utilizes spring-loaded PTFE and elastomer V-ring packing for extended service life. For steam applications, ensure the valve stem is mounted horizontally to protect the actuator from thermal stress.

• Connection: 3/4" NPT Threaded Female
• Flow Coefficient: 7.3 Cv (Equal Percentage)
• Body Material: Cast Bronze (ASME Class 250)
• Trim: 300 Series Stainless Steel
• Actuator: VA7810-HGA-2 Non-Spring Return (NSR)
• Control Type: Proportional (0-10V / 4-20mA), Floating, or On/Off
