Overview
CB304 safety valves are engineered for larger marine piping networks. The body uses high-strength cast steel to resist physical stress. Its
right-angle structure facilitates installation at corners or on vertical pipes.
right-angle structure facilitates installation at corners or on vertical pipes.
This valve suits fresh water, sea water, and low-pressure steam. The internal disc lifts rapidly when system pressure rises abnormally. Excess media vents through the side outlet. Such an automatic release mechanism protects expensive piping equipment from damage. The structure complies with B and BS type standards.
