Johnson Controls VG7243PT+3008B Valve Assembly

The Johnson Controls VG7243PT+3008B is a heavy-duty 2-way normally open globe valve assembly designed for precise flow control of hot water, chilled water, or steam in commercial HVAC systems. This 1 1/4" NPT valve features a cast bronze body and stainless steel trim, specifically engineered to withstand higher fluid temperatures and prevent premature wear from corrosive media. The assembly is equipped with a V-3000 series exposed pneumatic actuator, providing a 3-6 PSI spring range for reliable modulating or on-off service. With an 18.5 Cv rating and an equal percentage flow characteristic, this assembly ensures consistent performance and tight shut-off even in demanding pressure-drop scenarios. This pneumatic control valve is a standard choice for contractors looking for a field-serviceable solution that utilizes the traditional Johnson Controls ring pack packing for long-term seals. Whether managing terminal reheat or AHU coils, the VG7000 series valve delivers the mechanical durability required for professional HVAC systems.

• High-Temperature Durability: The stainless steel trim allows for standard use with saturated steam up to 100 psig and hot water up to 338°F.
• Precise Modulation: Features an equal percentage flow curve, providing stable control even at the low end of the stroke.
• Reliable Fail-Safe: The normally open spring return ensures the valve stays open during a loss of control air, protecting system flow.
• Field Serviceable: Designed with a standard bonnet and stem, allowing for in-place repacking and easy actuator interchangeability.

What media is this valve assembly compatible with?
The VG7243PT+3008B is rated for hot water, chilled water, and saturated steam commonly found in HVAC and industrial systems.

Can the actuator be replaced without removing the valve body?
Yes, the V-3000 pneumatic actuator is designed for easy field mounting and removal, provided there is sufficient clearance above the valve stem.

What is the maximum close-off pressure for this 1 1/4" assembly?
With the standard 3-6 PSI spring range, this unit typically handles a close-off pressure of approximately 35 psig, though this varies based on specific pneumatic pilot pressure.
