VRC to Hold New Valve Repair Event

vmsum12_vrcLike VMA, the Valve Repair Council is committed to education for those in the valve industry. VRC recently added a conference designed specifically for the valve and actuator repair and maintenance industry. The inaugural Valve Repair Meeting and Exhibition will be November 1 to 2 in Houston.

Documentation to Diagnostics: Trends in Valve Repair

vmspr12_valve_repairNot long ago, car owners often performed basic repairs and maintenance tasks themselves. Also not so many years ago, shoppers had to visit separate stores to purchase groceries, clothing, electronics, hardware and medicines. Neither of these scenarios applies to most of today’s consumers. The complexity of automobiles means even routine repairs and maintenance must be completed by trained mechanics using specialized equipment and computers. As far as shopping, the “super center” retailers offer the convenience of one-stop shopping for a vast array of products.

Common Bellows Failures and Suggestions for Mitigation


While it is an extremely rare event, bellows can and do fail. But bellows failures are often wrongly attributed to the quality of the valve or the bellows while in reality, a more likely scenario is operating conditions or an improperly specified valve that contributed to the failure. Still, whenever a failure occurs, analysis of what happened and why is critical.

Asset Management: A Plant Manager’s Best Friend

vmfall11_maintenance_tabletInformation about the performance of a facility’s valves has never been more readily available—or more important. Digital positioners and distributed controls can provide valuable data about the operation of the overall system. At the same time, the growing complexity of today’s facilities, increasingly stringent regulatory and reporting requirements, and growing pressure to improve plant performance have combined to make that valve data more vital than ever.

Preventive Maintenance and Repair for Sleeved Plug Valves

Preventive maintenance and repair for valves is an important part of keeping operations running smoothly and efficiently. For the sleeved plug valve (SPV), such maintenance is minimal—simply requiring an occasional adjustment to prevent both external and internal leakage in certain applications. The repair process for SPVs can be more extensive—inspection of parts and use of proper replacement parts are vital for ensuring a safe, successful overhaul. Additionally, root cause failure diagnosis is a critical part of this process. This is because the damage detected is the best indicator of the type of change to the valve or modification to the process that, if made, will extend the useful life of the valve.
