Brass safety valve, also known as a pressure relief valve. It is designed to automatically release a substance from a system when the pressure exceeds a preset limit. The text on the side of the valve reads "SNS 0.9MPa," which indicates the set pressure of the valve.
Function: It acts as a fail-safe device to protect equipment and prevent overpressure scenarios.
Mechanism: When the pressure inside the system surpasses the set limit, the valve opens to release the excess fluid. It closes again once the pressure returns to a safe level.
Material: The valve is made of brass, a common material for these devices.
Applications: Safety valves are widely used in various systems, including boilers, pressure vessels, and air compressors.
