Discontinued - Use 255TC-EIQ

This listing represents a discontinued Autotrol control valve assembly that has been superseded by the current 255TC-EIQ. The original unit, the Autotrol 255 Valve with a 460TC 6-Day Time Clock Controller and cover, served for years as a dependable time-clock-based control head for residential and light commercial water softeners on the Pentair Autotrol platform. Many of these units are still in service today, which is why knowing the correct replacement path matters when it finally comes time to upgrade an aging control head.

Recommended Replacement

Because this configuration is no longer produced, the recommended path forward is the 255TC-EIQ, which pairs the same proven Autotrol 255 valve body with the modern Easy-iQ controller. The Easy-iQ consolidates the functionality of several legacy controllers into one intuitive unit, offering adaptive learning, a clear LCD display, and simplified programming, a meaningful upgrade over the older 460TC 6-day time clock this part used. The valve body itself remains the same trusted, serviceable design, so the transition is straightforward and existing tank and plumbing connections generally carry over.

• Discontinued Autotrol 255 valve with 460TC 6-day time clock and cover
• Original alternate part number: 25440-BB00-SE6
• Built on the rugged, time-tested Autotrol 255 valve platform
• Superseded by the current 255TC-EIQ Easy-iQ assembly
• Easy-iQ upgrade adds adaptive scheduling and a modern display
• Recommended for those replacing or upgrading an aging 255 control

If you are servicing an existing system that used this valve, or planning a new softener build, the 255TC-EIQ offers backward-compatible performance with improved controls and easier setup. Because the Easy-iQ moves from a fixed time-clock schedule to adaptive regeneration, many users also see better salt and water efficiency after the switch, since the system regenerates based on actual usage rather than the calendar. The familiar 255 platform also means replacement seals, pistons, and brine components remain widely available, so ongoing maintenance is no harder after the upgrade than before. The Autotrol 255 valve body remains a robust, serviceable foundation, and moving to the Easy-iQ controller brings your system up to current standards while preserving the reliability the platform is known for. Confirm your configuration and order the 255TC-EIQ for the equivalent, up-to-date solution that will continue to be supported with parts and accessories.
