Johnson Controls VG7243NT+3008E Valve Assembly

The Johnson Controls VG7243NT+3008E is a professional-grade 2-way normally open valve assembly engineered for precise modulation of hot water, chilled water, and saturated steam in commercial HVACR systems. This 1-inch NPT threaded globe valve features a robust cast bronze body and 11.6 Cv equal percentage flow characteristic, ensuring stable control and linear heat transfer across varying terminal unit loads. Equipped with stainless steel trim, the assembly provides superior resistance to corrosion and scaling, significantly extending the service life of the control valve body in demanding hydronic loops.

The integrated V-3000-8012 exposed pneumatic actuator utilizes a reliable 9-13 PSI spring range for fail-safe spring return operation, ensuring the valve defaults to the open position upon loss of signal or air pressure. This pneumatic control valve is designed for easy field service, featuring a standard bonnet and stem that allows for actuator replacement or repacking without removing the valve from the piping. Whether managing heat exchangers or air handling units, this assembly provides the tight shutoff and high-rangeability performance required by modern building automation standards.

• Equal percentage flow characteristic optimizes valve authority and terminal unit control.
• Stainless steel trim prevents premature wear from high-velocity steam and aggressive water chemistivity.
• Normally open (N.O.) fail-safe configuration ensures continuous flow during power or air supply interruptions.
• High 11.6 Cv rating supports significant flow rates for 1-inch line size applications.
• Compact pneumatically actuated design allows for installation in tight mechanical spaces where electric actuators may not fit.

What is the maximum steam pressure for this valve?
The VG7000 series with stainless steel trim is typically rated for saturated steam up to 100 psig.

Can the actuator be rotated for better clearance?
Yes, the actuator can be repositioned by loosening a single set screw, allowing for optimal air line orientation.

Is this valve suitable for domestic water?
No, this bronze valve is specifically designed for closed-loop HVACR systems and is not lead-free rated for potable water.
