Johnson Controls VTM-XN047-312 / VG7291GT+3008B 3/4 Terminal Unit Valve
Johnson Controls VG7291GT+3008B valve: Type: This is a globe valve. Globe valves are known for their ability to regulate flow in a pipeline. Material: It's made of cast bronze, which is durable and resistant to corrosion, making it suitable for various HVAC applications. Size: The valve has a 3/4-inch connection size, which is a common size for many HVAC systems. Operation: It's a normally open valve, meaning it allows flow when no power is applied. It uses a push-down-to-close (PDTC) mechanism. Spring Range: The valve operates within a 3 to 6 PSIG spring range, which means it can handle pressures within this range. Actuator: It comes with a V-3000-1 actuator. Actuators are devices that control the valve's movement, and the V-3000 series is a pneumatic type, meaning it uses air pressure to operate. Flow Coefficient (CV): The valve has a CV of 4.7, which is a measure of the flow capacity through the valve. A higher CV indicates a greater flow rate. Connection Type: It features union sweat connections, which means it can be easily connected and disconnected using sweat (soldering) or union fittings. In summary, this valve is a robust, reliable component for controlling the flow of water or other fluids in HVAC systems. Its cast bronze construction ensures durability, and the V-3000-1 actuator provides precise control over the valve's operation.
