Introduction In municipal and industrial pumping systems, the selection of check valve technology is the primary defense against destructive hydraulic transients (water hammer) and reverse flow damage. Engineers are frequently faced with a divergent choice when specifying pump discharge control: specifying an active, electrically or pneumatically actuated solution (often synonymous with Rotork actuation on a […]

Introduction One of the most persistent yet overlooked threats to municipal pipeline integrity is the mismanagement of entrapped air and vacuum conditions. Design engineers often treat air valves as commodity items, specifying them based on nominal pipe diameter rather than hydraulic performance or operational longevity. This oversight frequently leads to catastrophic line failures due to […]

1. INTRODUCTION In the hierarchy of valves utilized within municipal and industrial water infrastructure, the cone valve occupies a unique tier reserved for the most critical, high-consequence applications. Often referred to as rotary cone valves or conical plug valves, these devices are engineered to provide full-bore flow with negligible head loss while possessing the mechanical […]
