V-4440-1001 Johnson Controls Valve

Datasheet

The Johnson Controls V-4440-1001 1/2″ H-C 4-12# Elbow 1.4

The V-4440 three-way valve is designed to accurately regulate the flow of hot or cold water in small room air conditioning three- or four-pipe systems. Two models are available; the supply valve with a 4 to 12 PSIG (28 to 84 kPa) spring range, and the return valve with a 6 to 9 PSIG (42 to 63 kPa) spring range.

The V-4440 supply valve has one normally open inlet and one normally closed inlet which are never open at the same time so there can be no mixing of hot and cold water. The supply valve, therefore, serves a dual purpose. It functions as a switching valve by supplying either hot or cold water, and acts as a control valve by modulating the flow of hot or cold water.

The V-4440 return valve has one inlet and a normally open and a normally closed outlet. This valve modulates within the dead zone of the supply valve to direct hot or cold water through the proper return circuit back to the supply valve.
