A Bermad pressure relief valve is a safety device used in fluid control systems to protect against excessive pressure buildup. It is designed to automatically open and release fluid when the pressure exceeds a predetermined set point, thus preventing potential damage or catastrophic failures.

Bermad pressure relief valves typically consist of a valve body, a spring-loaded mechanism, and an outlet port. When the pressure in the system exceeds the set point, the spring mechanism is activated, causing the valve to open and divert the excess fluid to the outlet port. Once the pressure returns to a safe level, the valve closes, restoring normal system operation.

These valves are available in various sizes and pressure ratings to accommodate different applications. They are commonly made from robust materials such as stainless steel or ductile iron to ensure reliability and durability.
