Freeflow underground hydrant with duckfoot bend

Because of the separation of operating and medium pipe the Hawle underground hydrant with integrally cast duckfoot bend features considerably better hydraulic conditions in open position than hydrants with conventional shut-off function via valve plug. Compared to conventional underground hydrants, the compact design ensures an extremely low dead water quantity and also permits easy and quick installation. Shut-off is effected via a shut-off blade of stainless steel. The shut-off blade is moved horizontally against fixed metal stops in a housing via eccentric mechanism and gear at low wear.

Q = 153 m³/h at 1 bar pressure difference
Min. cross section: 70 mm
Outlet: BAIO®, restraint loose flange
Opening/closing: 15 revolutions
Drain-off function: acc. to DIN EN 1074-6

When pipe fittings are to be connected to the type with horizontal BAIO® spigot end outlet, the twist lock device Ord. No. 529 (see supplementary products) shall be used.
