Specialized Refurbishment — CMO XB Series
We are pleased to offer a specialized refurbishment service for the CMO XB Series valves. In addition to our standard repair capabilities, we can now repair and re-line the polyurethane lining within these valves.
Through our proven refurbishment process, the existing polyurethane lining is removed, the valve body is thoroughly prepared, and a new polyurethane lining is applied — restoring the valve to its original operational performance and wear-resistant properties. The re-lined valve undergoes rigorous quality inspections and testing to meet our stringent requirements.
This service provides customers with a cost-effective alternative to valve replacement, extending service life while maintaining the high-performance standards expected from the CMO XB Series.
