Sulfur resistant safety valve is suitable for the working temperature of 300 ℃ or less steam, air, water, oil liquid ammonia, ammonia, nitric acid and other media equipment or piping as overpressure protection device.

The working principle of

The anti-sulfur relief valve has a protective effect on the system.
When the system pressure is more than a specified value, resistance to sulfur relief valve is opened, the system part of the gas/fluid atmosphere/pipeline, make the system pressure shall not exceed the allowable values, thus ensuring the system is not an accident because the pressure was too high.
