Johnson Controls VG7251NT+3008B 1" Globe Valve with Pneumatic Actuator 11.6 Cv 3-6 PSI

The Johnson Controls VG7251NT+3008B is a complete 2-way globe valve assembly designed for precise control of hot water, chilled water, and saturated steam in HVAC applications. This factory-assembled unit combines the VG7251NT brass trim globe valve with the V-3000-8012 exposed pneumatic actuator for reliable, proportional control in heating and cooling systems.

Valve Features:

• 1-inch union globe valve with bronze body construction
• Brass trim with stainless steel stem and molded elastomeric disk seat
• Flow coefficient (Cv) of 11.6 for efficient flow control
• 2-way, normally open configuration (push-down-to-close)
• Safe working water pressure up to 308 PSI
• Maximum water temperature rating of 284°F
• Safe working steam pressure of 38 PSI

Pneumatic Actuator Specifications:

• V-3000-8012 exposed yoke actuator with spring return
• 3-6 PSI spring range for proportional control
• 8 square inch effective diaphragm area
• Maximum control pressure of 25 PSI
• 1/8" NPT barbed fitting for 1/4" or 5/32" O.D. polytubing
• Molded synthetic rubber diaphragm in protective metal housing

This compact valve assembly is ideal for installation in fan coil units, baseboards, radiators, convectors, and other space-constrained HVAC applications. The normally open design ensures continuous fluid flow until the actuator receives a pneumatic signal to modulate or close the valve.
