Düker - Model 495 -Surface Hydrant

The hydrant complies with the standards for surface hydrants EN 14384 as well as DVGW testing specification W 386-P. It is also DVGW-certified. Other advantages: its cast iron, enamelled hand wheel is connected to the solid stainless steel stem extension by a parallel key. The two aluminium B-couplings according to DIN 14318 are well protected beneath the stainless steel protective cover. These can be operated individually using two valves. A safety valve prevents the protective cover from closing under pressure. It has a pre-determined breaking point and a double shut-off. The hydrant also has an outlet in the lower section with an A-fixed coupling according to DIN 14319 with an outlet cover. The polystyrene packaging of this hydrant can also be used as a drainage cylinder after delivery and installation. The Dueker surface hydrant 495 is incredibly clever.
