Johnson Controls VG7243LT+3008BP Valve Assembly

The Johnson Controls VG7243LT+3008BP is a heavy-duty 2-way normally open pneumatic globe valve designed for precise proportional control of hot water, chilled water, or steam in commercial HVACR systems. Built with a 3/4 inch NPT female threaded connection, this assembly features a cast bronze body rated for ANSI Class 250, ensuring long-term structural integrity in high-static pressure environments up to 400 psi. The stainless steel trim provides superior corrosion resistance and equal percentage flow characteristics with a 7.3 Cv rating, making it ideal for maintaining stable temperature gradients in air handling units and heat exchangers.

This unit is powered by a V-3000-8012 exposed pneumatic actuator equipped with a V-9502 positioner for enhanced accuracy. The spring return mechanism operates within a 3-6 psi spring range, ensuring the valve defaults to the open position upon loss of signal or air pressure. Featuring the Johnson Controls ring pack packing, this VG7000 series assembly minimizes leakage and extends service life during high-cycle operation. It is compatible with standard pneumatic controllers and handles medium temperatures ranging from 35°F to 338°F.

• Equal Percentage Flow: Provides predictable control and improved system stability under varying load conditions with a 7.3 Cv capacity.
• Durable Construction: The cast bronze body and stainless steel trim are engineered for steam and water applications, meeting ASME B16.15 standards.
• Fail-Safe Operation: The normally open configuration ensures constant flow during pneumatic failure, critical for freeze protection and process safety.
• Integrated Positioner: The factory-mounted V-9502 positioner eliminates hysterisis and provides precise stem positioning for the exposed pneumatic actuator.

What is the maximum steam pressure for this valve?
This assembly is rated for saturated steam applications up to 38 psig, with a maximum fluid temperature of 338°F.

Can the actuator be replaced in the field?
Yes, the VG7000 series features a standardized bonnet and stem design, allowing for straightforward field retrofit or replacement of the pneumatic actuator.

Does this valve require specific maintenance for the packing?
The Johnson Controls ring pack used in this 3/4 inch NPT valve is self-adjusting; however, periodic inspection for stem leaks is recommended in high-temperature steam service.
