VG7241RT+823C00 Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG7241RT+823C00 is a high-performance 2-way normally open pneumatic globe control valve assembly designed for precise modulating control in building automation systems. It features a cast bronze body with durable brass trim and is driven by an MP823C spring-return pneumatic actuator with a 3-7 psi spring range, ensuring reliable fail-safe operation during pressure loss.

Features

• 2-way normally open configuration ensures fail-safe protection by reverting to the open position upon pressure loss.
• Driven by an integral pneumatic actuator with a 3-7 psi spring range.
• Cast bronze body and brass trim offer superior corrosion resistance and longevity.
• Equal percentage flow characteristic provides precise throttling control.
• Engineered for tight shut-off capabilities, reducing energy waste and preventing bypass flow.

Specifications

• Valve Size: 1-1/2 inch NPT threaded connection
• Flow Capacity: 28.9 Cv
• Actuator Spring Range: 3 to 7 psi
• Media Compatibility: Hot water, chilled water, glycol solutions up to 50%, and steam up to 35 psig
• Temperature Range: Water from 35 to 248 degrees Fahrenheit; steam up to 284 degrees Fahrenheit
• Leakage Rating: ANSI Class IV (0.01% of maximum flow)
• Pressure Rating: ANSI Class 250, maximum water pressure up to 400 psi

Applications

• Modulating control for hot water, chilled water, and low-pressure steam in commercial HVAC systems.
• Maintaining setpoint accuracy in commercial air handling units and heat exchangers.
• Rugged fluid dynamics management within industrial and building automation networks.
