The product requires periodic inspection and cleaning to maintain maximum efficiency and long service life. AISI 316 stainless steel allows the valve to be used in both fresh and saltwater without risk of losing its anti-corrosion properties. The check valve prevents water backflow, protecting the installation from flooding. Installation is simple and can be performed during both construction and modernization of the vessel. It is recommended to use sealants designed for stainless steel. The product does not require specialized tools for operation—standard sailing tool sets are sufficient. Optionally, the installation can be supplemented with additional filters or protective elements compatible with 1½" threading.
