NUPI has recently completed the first production of its new ELOFIT HDPE ball valves. The valves, which are molded in black PE4710 (PE100) material are available in 1 inch through 4 inch diameters for use in both water and natural gas applications. ELOFIT is a High Density Polyethylene - HDPE PE100 system of electrofusion and spigot fittings and special components for the conveyance of water and gas under pressure. ELOFIT is suitable for the conveyance and distribution of drinking water and alimentary fluids, fuel and inert gases and for water treatment plants, centralised irrigation and sewage systems, fire protection systems and pipe relining. The ELOFIT system is mostly assembled through the electrofusion process. The main feature of ELOFIT fittings is the high quality and reliability of the welding. When it cools down, the connection is even, strong, safe and reliable.
