Product Detail

The marine spring-loaded full bore type lever safety valve is designed to be installed vertically, preferably directly on the adaptor of the container or pipe. The inside diameter of the adaptor should not be smaller than that of the valve’s inlet pipe.

To prevent thermal stress caused by the expansion of the discharge pipe, an expansion joint should be incorporated in the exit path of the safety valve. The inside diameter of the discharge pipe should be larger than the diameter of the valve’s exit way. The discharge pipe should be as short as possible without any bends, and its weight should not be supported by the safety valve. Both the discharge pipe and expansion joint should be securely fastened to the structure. The distance between the centerlines of the discharge pipe and the safety valve body should be minimized. Each safety valve should have a separate water drainage pipe.

The muffler’s exit path should have sufficient area to prevent back pressure that could impact the valve’s discharge capability. Ensuring proper muffler design and sizing is important for maintaining optimal valve performance.
