Trane VAL8025 Modulating Valve 1/2" 3W 3.8Cv

The Trane VAL8025 is a 1/2”, 3-way, modulating valve intended for chilled and hot water systems in HVAC applications. It employs a stem that lifts to near to control the flow of water in a system. The difference between modulating valves and on/off valves is that the former can control the flow rate of the fluid passing through them according to a signal from a thermostat or any other controller. This can help in better control of temperature and should result in less energy use. For connection purposes, the FNPT (Female National Pipe Thread) makes easy coupling into the existing piping system.
