Proven quality and reliability
This is the second time I've ordered these zone valves for my home heating needs. Very easy to install and they work great with my electronics for my hydronic heating system.

Lots of nice features
This model replaces an older version and the improvements are nice. The motor assembly can be easily removed/replaced without draining the system and the threaded version let us use quick connect fittings without the use of torches.
