Features and usages
Safety valves are used as over pressure protects devices on the pressure equipment, containers and pipes. They are reliable without leakage when the pressure is under the allowable value. As soon as the pressure of equipment and pipes increases and exceeds the allowable value, they automatically open and discharge so as to lower the pressure. Once the pressure decreases under the allowable value, they shut down quickly with perfect sealing property so as to guarantee safe operation.
