The Caleffi 521201AP SinkMixer is a thermostatic mixing valve designed for under-sink use, ensuring safe tempered water delivery. This valve features a patented low-lead brass body to provide high flow capacity while maintaining a compact design. Its four-port configuration simplifies installation and reduces the amount of piping required compared to standard three-port valves.
This mixing valve is ideal for applications where protection from scalding is necessary. It includes a plug for the cold outlet port, suitable for automatic sinks with a single connection for tempered water.
