Premium DIN Underground Fire Hydrants are only suitable for “OPEN – CLOSED” duty. Their main purpose is
the access and withdrawal of water in order to extinguish fires.
They comply with European standards DIN EN14339, DIN EN1074-6 and the relevant DVGW requirements W 386 (P), and they have
DVGW approval for drinking water as well as the CE mark according to European Construction Products Directive 89/106/CEE.
These hydrants are designed with a one-piece body. The stem bearing is trapped in the flange bearing without contact with the medium.
A safety interlock prevents ejection of the inner trim during dismantling work for maintenance. The cams at the outlet-claw prevent the
ejection of the standpipe under vibration conditions. The automatic drainaged device, placed on both sides, limits the amount of residual
water to a value below the requirement of the DIN standard.
They are proposed in Single Shut Off version (UHA) or Double Shut Off version (UHAD), and are available in STANDARD or PREMIUM
level of finish.
