This Johnson Controls valve regulates fluid flow in HVAC systems. It has a 3/4 inch port size and operates as a two-way valve. The valve features a flow coefficient (Cv) of 4.7, which indicates its capacity to pass fluid. It uses a 24V power supply for operation and functions in a two-position mode, either fully open or closed. The spring return mechanism ensures the valve returns to its normal open position when power is lost.
