ZVC vs SR: ZVC panels switch multiple zone valves; the SR501 through SR506 are single-zone switching relays for one circulator or valve — tell us the zone count and valve type and we will match the control.
Confirming the right part
This is a replacement part, not a whole pump. Before we quote, compare these fields on your failed pump's tag. If any of them differ, send us a photo and we'll match it exactly rather than guessing:
- Full part number — including the LF suffix where one exists
- Pump series and model the part came out of
- What's included: with vs. without impeller matters (e.g. 189134LF vs. 118844LF)
Which ZVC Zone Valve Controls do you have?
Send the exact model or part number off your nameplate. We'll confirm the match and quote it with availability and lead time.
