Underground Fire Hydrant DUO GOST for Reliable Fire Protection

underground hydrant with flanged connection
Working pressure: max. 16 bar (PN 16)
All internal parts made of corrosion-resistant material can be removed upwards without digging up the hydrant
The sealing piston, thanks to its vulcanised sealing profile made of ethylene propylene rubber, provides protection against water pressure and the tightness of the brass O-ring; The opening stroke of the piston forcibly controls the emptying function with protection against water pressure.
Complete emptying - zero water residual (RW 0).
