There is no point in buying a "good" valve and then paying to replace it over and over again. This kind of valve maintenance not only costs man hours; it costs even more in process down time. You can put a Durco SLEEVELINE® valve in your line and forget it. Long service life. The large sealing area of the Teflon* sleeve will withstand erosion, nicks, scoring and general wear for years in process l i q u i d s , gases or f**te^ slurries without leakage. Plugs and bodies are available in the right Durco alloys t o w i t h s t a n d specific corrosive conditions. In fact, some of the first Sleeveline valves sold over ten years ago are still in service in many of these applications. No lubrication. A T e f l o n sleeve surrounds the plug. Teflon's resiliency and low c o e f f i c i e n t of f r i c t i o n seal t i g h t , yet permit the plug to turn without backbreaking effort. Simple adjustment for wear. The thickness of the Teflon sleeve allows for up to 14" °f vertical adjustment for wear before sleeve r e p l a c e m e n t becomes necessary. No machining or replacement parts. When wear or damage require replacement of a sleeve or plug there is absolutely no machining or fitting. No disc a s s e m b l i e s have t o be r e g r o u n d or fitted, no plugs have to be lapped. New Durco plugs will seal in old sleeves— new Durco sleeves will seal around old plugs. There is complete interchangeability of new and old parts in any Durco valve of a given size. * DU PONT REGISTERED TRADEMARK
