Marine Flange Check Valve
Marine flange check valves are typically constructed from materials that can withstand the harsh conditions of marine environments, including corrosion-resistant alloys such as stainless steel, bronze, cast iron, cast steel or duplex stainless steel.
Overview
Flange Connections:
Flanged ends provide a convenient means of connecting the valve to the pipeline. The flanges are usually designed to match standard pipe flange dimensions, such as ANSI, DIN, or JIS standards, facilitating compatibility and easy installation.
Pressure Ratings:
Marine flange check valves are available in various pressure ratings to accommodate different system requirements. They are designed to withstand high pressures commonly encountered in marine hydraulic systems.
