FAST AND EASY TO INSTALL FITTINGS & JOINTS

STINK-SHIELD ® ANTI-SMELL SHIELD / VALVES FOR UNITARY NETWORKS INTRODUCTION The city centers of our cities are invaded at certain times of the year by the smells coming from the pavement drains. This phenomenon is due to: •  the presence of an unitary evacuation network; •  the drying out of the siphons installed in the storm water manholes; •  tmospheric pressure variations that generate air flows between the inside and the outside of a the networks. To stop these smells, NORHAM has developed an innovative process: the STINK-SHIELD® and STINK-SHIELD® VERTICAL anti-smell valves. • ...

STINK-SHIELD ® ANTI-SMELL SHIELD / VALVES FOR UNITARY NETWORKS PRINCIPLE OF OPERATION IN RAIN WEATHER: NORMAL EVACUATION OF WATER During rainfall, the rain water level rises to the level of the STINK-SHIELD® VERTICAL anti-smell valve. Under the effect of the thrust of water, the membrane opens and allow the rainwater to drain to the collector. Pavement / sidewalk Pavement / sidewalk 1. Very low flow allows evacuation through the anti-smell valve. 2. When the drains are fully loaded, the 3 membranes of the STINK-SHIELD ® VERTICAL are totally open. Rainwater evaporation Pavement / sidewalk...

STINK-SHIELD ® ANTI-SMELL SHIELD / VALVES FOR UNITARY NETWORKS PERFORMANCE Tests were carried out by the CSTB (Scientific and Technical Center of Building), in order to establish and validate the performance of the anti-smell valve STINK-SHIELD® VERTICAL. HYDRAULIC CAPACITY: THROUGHPUT ≥ 60 l/s A 700 mm x 700 mm large drain grid has a maximum throughput of 60 l/s. The STINK-SHIELD® VERTICAL must be able to evacuate a flow rate at least equivalent to the drain grid. The valve has superior hydraulic capacity* when the water level in the manhole exceeds 0,8 mWC . 200 Troughflow according to...

STINK-SHIELD ® ANTI-SMELL SHIELD / VALVES FOR UNITARY NETWORKS STINK-SHIELD® In dry weather, the elbows (siphons) that equip the drains of our streets are no longer effective because they are no longer immersed. To relay the anti-smell function when the drain is dried, NORHAM has designed an innovative process: the STINK-SHIELD® anti-smell valve. TECHNICAL DATA •  Body: recyclable elastomer type SEBS; •  clamp: stainless steel AISI 304; •  DN: 200 mm. STINK-SHIELD® inside view Installation on a PVC elbow (not included). OPERATING PRINCIPLE IN RAINY WEATHER: NORMAL EVACUATION OF WATER • ...

STINK-SHIELD ® ANTI-SMELL SHIELD / VALVES FOR UNITARY NETWORKS PERFORMANCE Tests have been carried out by the CSTB (Scientific and Technical Building Center) to establish and validate the performance of the STINK-SHIELD® anti-smell valve. FLOW THROUGH ≥ 60 l/s A large drain grid 700 mm x 700 mm has a maximum through flow of 60 l/s. The valve must allow to evacuate a flow at least equivalent. Tests show that it meets this criterion in every respect. The STINK-SHIELD even has a higher capacity when the water level in the rainwater manhole exceeds 1,2 mCE. The hydraulic capacity* of the «elbow...
