"SR" in the context of a pneumatic valve typically stands for "Safety Relief." A safety relief valve is a type of pneumatic valve that is designed to prevent overpressure or vacuum conditions in a system by releasing the air or gas when the pressure exceeds a certain threshold.

The primary function of a safety relief valve is to protect the system and its components from damage that can be caused by excessive pressure. When the pressure in the system reaches the set pressure of the valve, the valve opens and allows the air or gas to escape until the pressure drops back to a safe level.

Pneumatic safety relief valves are commonly used in various industrial applications, such as air compressors, pneumatic tools, and HVAC systems, to ensure the safe operation of the equipment and to prevent accidents or injuries.
