Freeflow underground hydrant

Cast components: GJS-400, Hawle epoxy powder coated Medium pipe: stainless steel, Hawle epoxy powder coated Spindle/shut-off blade/shut-off device: stainless steel Protection jacket: PP (polypropylene) Gaskets: EPDM acc. to KTW-BWGL for water |

Because of the separation of operating and medium pipe the freeflow underground hydrant features considerably better hydraulic conditions in open position than hydrants with a conventional valve plug as shut-off device.
Shutting off is effected via a shut-off blade of stainless steel. Via an eccentric mechanism and a gear the shut-off blade is moved in a housing at low wear in horizontal direction against fixed stops.
Q = 153 m³/h at 1 bar pressure difference
Min. cross section: 70 mm
Outlet: BAIO®, flange or PE
Opening/closing: 15 revolutions
Drain-off system
CE marking
For hydrants with BAIO® spigot end outlet the dirt cover and locking ring (see supplementary products) shall be used.
