Specs At A Glance

Good To Know

Q: Can I replace just the power head instead of the whole zone valve? A: Yes, the power head is the serviceable upper portion that mounts to the valve body. If the body is in good shape, swapping the head is the standard repair.

Q: How do I confirm this head matches my valve? A: Match the 555-050RP number and the valve series stamped on your existing body. Confirm the series number before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
