Johnson Controls VG7241RT+823E01 Valve Assembly

The Johnson Controls VG7241RT+823E01 is a heavy-duty 2-way globe valve assembly engineered for precise proportional control in commercial HVACR systems. This unit features a 1-1/2 inch NPT threaded connection and a robust cast bronze body paired with durable brass trim, ensuring reliable performance in hot water, chilled water, or 35 psig steam applications. With a 28.9 Cv flow coefficient and an equal percentage flow characteristic, it provides stable modulation even at low flow rates, preventing hunting in your control loops.

The assembly is powered by a high-performance MP8000 series pneumatic actuator with a factory-integrated positioner. This spring return pneumatic actuator operates with a 9-13 psi spring range and maintains a normally open (spring return up) fail-safe position. Built to withstand demanding mechanical room environments, the VG7000 series valve and actuator combination offers an ANSI Class 250 static pressure rating, making it a staple for contractors looking for pneumatic control valve solutions that deliver long-term serviceability and consistent close-off integrated for Johnson Controls building automation systems.

• Precise Modulation: The equal percentage flow curve ensures linear heat output for superior temperature control in air handlers and heat exchangers.
• Reliable Fail-Safe: The normally open spring return mechanism provides a critical safety default, ensuring flow continues during a loss of signal or air pressure.
• Enhanced Durability: Constructed with a cast bronze body and brass trim to resist corrosion and handle fluid temperatures up to 248°F.
• Integrated Positioner: The factory-installed positioner ensures the pneumatic actuator accurately tracks the controller signal, overcoming friction and stem forces.

What media is compatible with the VG7241RT+823E01?
This Johnson Controls valve is rated for hot water, chilled water, and 50/50 glycol solutions. It is also suitable for saturated steam applications up to 35 psig.

Can the actuator be serviced without removing the valve body?
Yes, the VG7000 series allows for the MP823E01 actuator to be removed or replaced while the valve body remains in the line, and the valve can be repacked in place to minimize downtime.

What is the close-off pressure for this 1-1/2 inch assembly?
When paired with the 25 sq. in. pneumatic actuator, this assembly typically provides a close-off pressure of approximately 58 psi, though actual results depend on supply air pressure.
