Johnson Controls VG7241LT+3003B Valve Assembly

The Johnson Controls VG7241LT+3003B is a professional-grade VG7000 Series globe valve assembly designed for precise water and steam regulation in commercial HVAC systems. This 2-way normally open valve features a robust 3/4-inch NPT connection and a 7.3 Cv flow coefficient, utilizing an equal percentage flow characteristic to ensure stable modulating control across varying load conditions. Built for long-term field reliability, the assembly consists of a cast bronze body paired with durable brass trim, capable of handling fluid temperatures ranging from 35 to 284°F and saturated steam up to 38 psig.

The integrated V-3000 pneumatic actuator is an enclosed, spring-return unit featuring a 3-6 psi spring range. This setup ensures the valve defaults to the open position upon loss of signal or air pressure, providing a critical failsafe for heating or cooling loops. The spring return pneumatic actuator is engineered for high-cycle performance, utilizing a long-life replaceable ring packing that minimizes maintenance requirements and guarantees a tight shut-off against high return pressures. For contractors and technicians, this Johnson Controls pneumatic valve offers an industry-standard solution for terminal units, air handlers, and heat exchangers.

• Precision Modulating Control: The equal percentage flow design provides superior authority in hydronic and steam applications.
• Reliable Failsafe Operation: Normally open configuration ensures continuous flow during power or pneumatic supply failures.
• Durable Construction: Cast bronze body and brass trim meet ASME B16.15 Class 250 standards for high-pressure environments.
• Serviceable Design: Features a replaceable ring packing system, allowing for in-line maintenance without removing the valve body.

• What is the maximum steam pressure for this assembly? This model is rated for saturated steam up to 38 psig, though always verify your specific system's close-off requirements.
• Can the actuator be replaced in the field? Yes, the V-3000 series actuator is field-replaceable and can be mounted without special tools once the system is depressurized.
• Is a positioner compatible with this model? While some VG7000 units allow for positioners, this specific enclosed actuator assembly does not typically support a factory-mounted pneumatic positioner.
