Johnson Controls VG7241RT+823E00 Valve Assembly

The Johnson Controls VG7241RT+823E00 is a heavy-duty 1 1/2-inch NPT pneumatic globe valve assembly engineered for precise modulating control in commercial HVACR systems. This 2-way normally open valve features a robust cast bronze body with brass trim, providing durable service for chilled or hot water and steam applications. With a 28.9 Cv rating and an equal percentage flow characteristic, it ensures stable linear control even under varying pressure drops. The assembly is driven by a high-torque spring return pneumatic actuator with a 9-13 PSI spring range, ensuring a reliable fail-safe position during a loss of signal. This VG7000 series valve is designed for high-cycle life, making it a standard choice for technicians managing proportional pneumatic control setups.

Key Benefits:

• Precision Throttling: The equal percentage plug design provides superior control for heat exchangers and air handling units.
• Reliable Fail-Safe: The normally open spring return configuration ensures the valve opens fully upon air pressure loss to prevent system freezing or stagnation.
• Durable Construction: The bronze body and brass trim resist corrosion and wear in high-demand fluid applications.
• High Flow Capacity: Rated at 28.9 Cv, it handles significant flow rates with minimal pressure drop across the 1.5-inch port.
• Standard Compatibility: The 9-13 PSI spring range integrates seamlessly with standard pneumatic controllers and building automation systems.

Common Questions:

What media is this valve compatible with?
The VG7241RT is compatible with water, glycol solutions up to 50%, and saturated steam up to 38 psig. Always verify the maximum fluid temperature against the packing material specifications.

Can the actuator be replaced in the field?
Yes, the pneumatic actuator is field-replaceable, allowing for maintenance without removing the entire valve body from the piping system.

What is the maximum pressure rating for this assembly?
This 1-1/2" NPT assembly generally adheres to ASME Class 250 pressure-temperature ratings. Ensure your system's static and dynamic pressures do not exceed the body's rated limits.
