Everlasting 4000 Series Handwheel Valve
Everlasting Valve introduced the 4000 series original self-lapping, rotating-disc valve to the world in 1906, and it’s been the gold standard for severe-service valves ever since. Each time the disc rotates, it produces an action that renews and polishes the metal seating surfaces. As a result, each Everlasting Valve wears in with use. This is the slow opening handwheel operated version for performing the actual blowdown operation.
