Description

Double plate check valve mounting between flanges, ductile iron GGG40 housing, EPDM seal for DN50-300 & DN400 and NBR seal for DN350 & DN450-600, stainless steel 316 spring and stainless steel 304 disc for DN50-300 & DN400 and aluminum bronze disc for DN350 & DN450-600 to prevent liquids or gases from flowing back. The valve thus offers one-way passage. The disc opens as soon as the minimum opening pressure is reached. As soon as the pressure decreases, the non-return valve closes by means of the spring. The check valve is suitable for general industrial applications.
