- Features
- Die Erste is proud to present Series 1T, Top-Entry ball valve for a revolutionary easy in-line maintenance experience. Better yet, equipped with the ever-important ISO 5211 direct-mounting pad, Series 1T offers the flexibility to be automated with actuator, or operated manually with hand lever.
Conventional v-style wedge-seated top-entry ball valves allow access to the body cavity without dismantling the valve from the pipeline, however requiring special tools and highly experienced workers to take out both ball and seats with care and precision.
Series 1T Top-Entry ball valve offers easy and direct maintenance with special "basket" design, without the need for special tools or highly trained workers. In an instant, both the ball and seats can be lifted in the "basket" designed to contain both parts.
