Check valves

Zenit check valves, certified EN 12050-4 annex ZA standard EN 12050-4, are designed for use even with soiled liquids and provide full guarantees of operation even under heavy-duty working conditions.
The sinking ball system ensures a free passage since, at maximum opening, the valve has a completely free main line, greatly reducing pressure drops.
The fact that it can be installed in a horizontal or vertical position provides greater versatility and optimal assembly.
Clapet valves can be used for non abrasive clear wastewaters. Zenit models have a structure and disc made of GJL-250 cast iron and a seat of brass and EPDM rubber. The lever, which allows the mechanism to be moved, is made of GJS 400 cast iron in order to provide maximum reliability. The conformance to international design regulations expedites the installation and makes them compatible with any standard flange.
