Hello,
My radiant heat system has four zone valves that are 20 years old and I wish to replace/upgrade them. The current valves are discontinued. They are SPARCO Power Track 24v 4-wire 2-way normally closed with 3/4" threaded valve body connections. I have attached a picture of one of the valve bodies I removed. I "think" they refer to these as a flared or inverted flare connection but I am not a plumber. Do you have zone valves/connections that would adapt to my system (remove old, insert new)?

Thank you!
