Directly Buried Ball Valve

MODEL BURIED VALVE-DN200-PN25-WE

Fully welded ball valve for direct burial, DN50 to DN1400 at PN25. The stem is extended to the depth you specify — 500 to 2000 mm — and ends in a handwheel inside a protective well, so a line under a road or a yard can be isolated without excavation. Supplied with 3PE coating and an anti-corrosion wrap on the extension.

WHY THIS SERIES

Reaches the surface

Stem extension to your trench depth, ending in a handwheel inside the well.

No chamber required

Directly buried, so there is no valve chamber to pour, drain or maintain.

Coating built for soil

3PE over an epoxy base, with the extension and well wrapped against corrosion.
