SAFETY VALVES

Safety valves are protection devices designed to control the pressure in a system and prevent it from exceeding a maximum operating value. They are used in a variety of applications, including steam, compressed air, gas, and liquid systems.

These valves work by opening automatically to allow excess pressure to be released from the system, preventing damage to equipment or piping and reducing the risk of accidents. When the pressure within the system reaches a predetermined level, the safety valve opens, allowing excess pressure to be released until the pressure returns to a safe level.
