Johnson Controls VG2231TM Valve

The Johnson Controls VG2231TM is a robust 2-1/2 inch two-way normally open globe valve designed for precision regulation in commercial HVACR systems. Built with a heavy-duty ASME Class 125 cast iron body and durable brass trim, this valve is engineered to handle chilled water, hot water, and 50 psig saturated steam applications. The modified linear flow characteristics ensure stable control across a wide range of demand, minimizing hunting and improving overall system efficiency. This specific model features a 51 Cv flow coefficient and a 3/8-inch threaded stem designed for push-down-to-close (PDTC) action, making it a reliable choice for field-mounting with pneumatic or electric actuators.

Installers prefer the VG2000 series for its versatility and high close-off ratings, reaching up to 115 psig depending on the actuator pairing. The flat-faced flange connection simplifies integration into existing piping, while the field-replaceable EPT packing extends the service life of the assembly without requiring full valve replacement. Whether you are managing large air handling units or steam-to-water heat exchangers, the VG2231TM globe valve provides the thermal and pressure tolerances required for demanding hydronic environments.

• Durable Construction: Features a high-tensile cast iron body and brass internal trim to withstand rigorous HVAC service.
• Precision Control: The modified linear flow drum provides accurate throttling for consistent temperature management.
• High Temperature Rating: Capable of handling fluid temperatures ranging from 35°F to 281°F at various pressure levels.
• Standardized Compatibility: The 3/8" threaded stem allows for easy pairing with a broad range of Johnson Controls actuators, including the MP8000 and M9000 series.

What is the maximum steam pressure for the VG2231TM?
This valve is rated for up to 35 psig of saturated steam when used in standard HVAC applications, though the body itself can handle higher static pressures for water service.

Is this valve sold with an actuator?
The VG2231TM is typically sold as a valve body only (Less Actuator), allowing for field assembly with either pneumatic or electric 24V actuators based on your control signal requirements.

Can the packing be serviced without removing the valve from the line?
Yes, the ethylene propylene terpolymer (EPT) ring packs are designed to be field-replaceable, reducing downtime during routine maintenance.
