Mokveld RZD Valve Refurbishment & Upgrade – 7 1/16″ 10,000 PSI
Delta Controls successfully completed a full refurbishment and modification project for a Mokveld RZD valve (7 1/16″ – 10,000 PSI), restoring performance and extending service life under demanding operating conditions.
The project was initiated due to leakage behind the seat ring, caused by erosion damage to the valve body. In addition, the actuator cylinder showed significant corrosion, impacting reliability and operational safety.
To address these issues, Delta Controls carried out precision machining and applied an F316 weld overlay to the actuator components. This upgrade significantly improves corrosion resistance and enhances overall durability. As part of the scope, the valve also received a functional product upgrade, bringing it in line with current performance standards.
All refurbishment and modification work was performed in accordance with original factory specifications. The valve was fully tested to ensure compliance with OEM standards and was successfully recommissioned by the end user.
This solution provided a cost-effective alternative to OEM replacement, delivering high-quality performance at significantly reduced costs while maintaining full operational integrity.
