Our PERMA/flo "XT & XL" Extreme Rotary Valve is the top choice for customers who value long life, rugged durability, ease of maintenance, and superior quality. Known for lasting up to five times longer than competitors' products, these rotary valves eventually require repair or rebuilding.
Delta Ducon offers an MRO-based rebuild program designed to evaluate, regrind, or repair your XT and XL rotary valves, minimizing downtime and restoring them to like-new performance.
​
The rotor and seal shoe of the XT and XL valves are heavy castings made from a special P-33 chrome-iron alloy, providing a hardness of 500-600 Brinell. Delta Ducon can regrind these components to maintain the tight clearances needed for your application.
Unlike other valves that feature surface hardening that wears down to expose a softer metal base and are often discarded once worn, our valves are built to last and be restored.
​
Whether you need minor repairs or complete rebuilding, Delta Ducon’s Rebuild Program is tailored to meet your MRO requirements and reduce downtime.
