D559B-8M safety valve
In a pneumatic transmission system, a safety valve is a valve used to prevent damage to pneumatic devices, equipment and pipelines and limit the maximum pressure of the circuit. When the air pressure exceeds the maximum limit pressure, the safety valve automatically opens to exhaust, and when the air pressure is lower than the maximum limit pressure, the safety valve automatically closes.
