A41H spring micro-open closed relief valve is suitable for oil, gas, air, water and other media equipment or pipelines whose working temperature is less than 300%. A41Y-P/R type is suitable for equipment or pipeline with corrosive medium working temperature less than 200 ~C as overpressure protection device. When the pressure in the equipment and pipeline exceeds the allowable value, the valve opens automatically, and then discharges completely. When the pressure drops to the prescribed value, the valve closes automatically to ensure the safe operation of the equipment and pipeline.
