Angel Type Self Closig Valves
Our angle type self-closing valve is a spring-loaded marine valve designed to automatically return to the closed position after manual operation. The 90° angle body configuration allows for easy installation in compact piping layouts, while the robust bronze construction provides excellent corrosion resistance in seawater and harsh marine environments.
Overview
Application : Angle type self-closing valves are essential components in marine and offshore piping systems where automatic shut-off is required for safety, environmental protection, or operational efficiency. Their spring-return design ensures the valve always fails closed, making them ideal for discharge and drain applications.
