The ball check valve prevent the viscouses, thicks and with metals in suspension fluids back-flowing. Could be installed in vertical or in horizontal position, but the fluid flow has to be the one described by the arrow on the valve body.Si può installare sia in posizione orizzontale che verticale, purché la direzione del fluido a valvola aperta avvenga nella direzione indicata dalla freccia. The top temperature for the fluids has to be 70°C and the max allowed pressure is 16 bar, exception for DN 250 and DN 300 that is 10 bar. The seal is granted by a rubber ball. This valve has to avoid aggressive fluids.
The ball is covered with NBR. The threaded type is appliant to standard ISO 228. For the flanged type, the occupancy area is in compliance with standard EN 558-1. The flanges are drilled according to EN 1092-2.
The valve is designed to have the full flow when open and some minimal loss in load. Average gauge of the epoxy painting: 250 µ.
N.B. With drinking water the minimum pressure has to be at least 2 Bar.
