Trane VAL19357 1/2" 3-Way Modulating Valve 120 Sec 24V

The Trane VAL19357 is a modulating 1/2” three-way valve for controlling flows in HVAC systems. Unlike a standard on-off valve, it regulates and opens, in response to a signal from a thermostat or control system, to ensure maximum comfort and efficiency. It is operated on 24V low voltage which is secure and simple to incorporate in numerous HVAC systems. The 120-second run time means the maximum time it takes for the valve to go from fully open to fully closed. Trane modulates system operation by precisely regulating hot or chilled water flow to maintain the desired temperatures. The valve can optimize system operation and save energy by avoiding superfluous heating or cooling cycles.
