Globe Type Self Closig Valves
Our globe type self-closing valve features a straight-through body design with a spring-loaded mechanism that automatically returns the valve to the closed position when operating force is removed. The inline configuration provides a more direct flow path with lower pressure loss compared to angle pattern designs, making it ideal for installation in straight-run piping systems where automatic shut-off is required.
Overview
Application : Globe type self-closing valves are installed in straight-run piping systems where automatic shut-off is essential for safety, environmental protection, or process integrity. Their inline design makes them the preferred choice for applications where an angle pattern valve is not practical due to piping layout constraints.
