In Reply to: Bang when zone valves close. posted by Bob on January 11, 2004 at 10:00:41:
: Last year I bought this 16 year old house. It has a new furnace, 2 years old. I have read some info on zone valves. Some suggest putting them on the return end of the loops, some suggest a hammer arrester, or seperate circulator on each line and some suggest putting in a differential pressure buypass. I tried removing one of the springs on each Honeywell v8043 but that didn't help much. Any thoughts out there to what is the best to do????
Caleffi motorized zone valves from Caleffi North America Inc. in Milwaukee manufacture a hi-close off, slow closing, actuator that helps minimize any potential for water hammer. It uses a newer technology than other straight thru pattern zone valves. Tel: 414.421.1000
