V-4440-1008

The V-4440-1008 from Johnson Controls is engineered as a three-way pneumatic water return valve essential for directing water flow in heating and cooling systems. This valve is constructed with a cast brass body, providing durability and reliability in various environments. Weighing 4.44 lbs, its design includes a 90° elbow configuration, featuring S.A.E. 45° flare connections that facilitate seamless integration into existing piping systems.

With a valve size of 1/2 inches, it ensures efficient operation and handling of flow rates. The flow coefficient of 2.4 Cv indicates its ability to manage significant volume flows while maintaining optimal pressure conditions. Specifically designed for return circuits, this valve operates effectively between a spring range of 6 to 9 psig, allowing for precise control of hot and cold water within 3- or 4-pipe systems.

An exposed pneumatic actuator (V-3000-1) is employed in this assembly, crafted from die-cast aluminum housing and featuring a synthetic rubber diaphragm for enhanced performance. The port configuration comprises one inlet, one normally-open outlet, and one normally-closed outlet to assist in efficient operation based on system requirements. Each valve is equipped with two modulating plugs that allow for the use of replaceable composition discs, granting maintenance flexibility and extending the unit's lifespan.

For applications requiring position feedback and control, the valve can be made compatible with the optional V-9502 pneumatic positioner, adding further functionality to the system. Overall, the Johnson Controls V-4440-1008 valve is tailored for applications that demand precise flow management in HVAC systems.
