The Johnson Controls V-4440-1002 is a three-way pneumatic water supply valve designed to function efficiently in various hydraulic systems. This unit features a 90° elbow body style that includes S.A.E. 45° flare connections for reliable attachment to plumbing systems. It has a size of 1/2 inches, making it fitting for numerous applications where water regulation is essential.

The valve is constructed from cast brass, ensuring robust durability while the stem is made of stainless steel to withstand wear over time. With a flow coefficient of 2.4 Cv, this valve ensures adequate flow capacity to meet system demands. It operates effectively within a spring range of 4 to 12 psig, providing flexibility in operation suited for different pressure levels.

This three-way valve includes a port configuration that features one normally open inlet and one normally closed inlet, ensuring that both inlets cannot be open simultaneously to prevent cross-flow. The inclusion of two modulating plugs enables a characterized lift-to-flow relationship, promoting smooth transitions in flow rates.

The V-4440-1002 is particularly suited for regulating hot and cold water in both 3- and 4-pipe systems. It serves a dual purpose as it acts as both a switching valve and a control valve. For enhanced control capabilities, it is compatible with the optional V-9502 Pneumatic Positioner, facilitating precise adjustments to flow characteristics. This valve's design ensures reliability and efficiency, contributing to effective fluid management in various systems.
