Johnson Controls VG7243PT+3008E Valve Assembly

The Johnson Controls VG7243PT+3008E Valve Assembly is a high-performance 1 1/4 inch NPT globe valve engineered for precise modulation in commercial HVAC systems. This 2-way normally open assembly features a rugged cast bronze body and superior stainless steel trim, specifically designed to withstand the rigors of saturated steam, hot water, and chilled water applications. With an 18.5 Cv rating and an equal percentage flow characteristic, it ensures stable control loops and prevents hunting in complex hydronic circuits. The integrated spring return pneumatic actuator provides a reliable failsafe, utilizing a 9-13 PSI spring range to return the valve to the open position upon loss of air pressure. This VG7000 series assembly is built for ANSI Class 250 static pressure environments and can handle fluid temperatures up to 338°F, making it a staple for veteran mechanical contractors requiring durable pneumatic control valves for mission-critical environmental regulation.

• High-Temperature Durability: The stainless steel trim allows for operation in saturated steam systems up to 100 psig.
• Precise Flow Control: Equal percentage flow profiling ensures linear heat output in relation to the controller signal.
• Reliable Failsafe: The spring return exposed pneumatic actuator ensures the valve remains in the open position during power or air loss.
• Serviceable Design: Features standard Johnson Controls ring pack packings for simplified field maintenance and long-term HVAC valve reliability.
• Robust Construction: Meets ASME B16.15 Class 250 requirements for high-pressure commercial piping.

What is the maximum fluid temperature this assembly can handle?
Equipped with stainless steel trim, the VG7243PT+3008E is rated for water and steam temperatures up to 338°F (170°C).

Is the actuator suitable for outdoor installation?
This model features an exposed pneumatic actuator; while rugged, it should be protected from direct weather exposure and dripping water to ensure optimal mechanical movement.

What air pressure is required for operation?
The actuator operates on a 9-13 PSI spring range, though the maximum air supply pressure should generally not exceed 25 psig to protect the internal diaphragm.
