Description

Double plate check valve mounting between flanges, gray cast iron GG25 housing up to DN150 and GGG40 housing from DN200, EPDM seal, stainless steel 316 spring and stainless steel 304 disc 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 clear water, water distribution and gas.
