Johnson Controls VG7443CT+72CHGA Valve Assembly

The Johnson Controls VG7443CT+72CHGA is a 1/2 inch NPT globe valve assembly designed for precision control of hot water, chilled water, and steam in commercial HVACR systems. This 2-way normally closed configuration features a rugged cast bronze body with high-grade stainless steel trim, specifically engineered to resist korrosion and extending the service life of the valve plug and seat. With an equal percentage flow characteristic and a 0.73 Cv rating, this assembly ensures stable modulating control even at low flow rates, preventing hunting in sensitive hydronic loops.

The integrated VA7820-HGA-2 spring return actuator provides reliable fail-safe operation upon loss of power. This versatile 24Vac actuator supports 0(2)-10vdc, 0(4)-20mA, two-position, or floating control signals, all of which are field selectable via onboard DIP switches. Designed for high-performance applications, the VG7000 series assembly handles fluid temperatures from 35°F to 284°F and is rated for saturated steam up to 38 psig, making it a standard choice for Johnson Controls VG7443CT replacements and new modulating control valve installations.

• Enhanced Durability: The stainless steel trim provides superior resistance to scaling and wear compared to standard brass internals.
• Fail-Safe Logic: Mechanical spring return ensures the valve returns to the closed position during power interruptions, protecting equipment.
• Flexible Control: Supports multiple input signals (Proportional, Floating, On/Off) to match existing building automation system (BAS) requirements.
• Tight Shut-off: Every VG7443CT+72CHGA is factory-tested to ensure reliable closure and minimal leakage.

• What is the maximum pressure for steam applications? This valve assembly is rated for saturated steam up to 38 psig at 284°F.
• Can I change the control signal in the field? Yes, the 72CHGA series actuator features field-selectable switches for voltage, current, and floating control modes.
• Is this valve suitable for glycol solutions? Yes, the bronze body and stainless trim are compatible with standard glycol-based heat transfer fluids utilized in HVAC systems.
