#116 Tufline valves prove that they can dramatically reduce valving costs.  Problem: How do plant engineers convince management to invest in quality Tufline valving?  Solution: They point out Tufline's extremely low, long-term cost of ownership. They point out that Tufline valves pay for themselves many times over with greatly extended service life, more productive uptime, and reduced maintenance. They show them a copy of a recent article which appeared in Hydrocarbon Processing Magazine titled: "Reduce Losses Through Smarter Valve Selection". We will be glad to send you reprints. They calculate their true valving costs using the factors indicated below: + Initial Price Monitoring Costs Service (And Downtime) Repair (And Downtime) Parts Premature Replacement (And Downtime) = Cost Of Valve Ownership  Results: In the examples below, Tufline valves dramatically reduced the cost of valve ownership. In a steam handling application, Tufline Sleeved Plug Valves are still going strong after 25 years of continuous service. In an application where descaling chemicals were rapidly corroding stainless steel valves, Tufline Lined Ball Valves are providing many times the service life. In anhydrous ammonia and hydrofluoric service, sleeves in competitor valves were turning in the valve bodies, making shutoff impossible. The Tufline Sleeved Plug Valves that replaced the failing valves have now been in service for years with no problems. Nickel-Chromium valves were failing in fluorspar slurry service. The Tufline Lined Plug Valves that replaced them lasted four times longer. High-alloy valves handling nitric acid at 248 degrees F failed in just six months. Based upon preliminary evaluation of Tufline Lined Plug Valves in the same service, they will probably last ten years. Index of all performance report case histories.
