Proportional angle spring safety valve with flanged ends with a high degree of tightness. The body of the product, depending on the model, may be made of grey cast iron (DN 15-200 for pressure up to 16 bar and max. temperature 300°C), acid resistant steel (DN 20-100 for pressure up to 40 bar and max. temperature 300°C, or cast steel (DN 20-200 for pressure up to 40 bar and max. temperature 450°C). Valves made of grey cast iron(DN 15 – DN 125) and cast steel (DN 20 – DN 125) can be equipped with a soft sealing disc. The valve can be used in shipbuilding, food, chemical, heating, energy, petrochemical and refrigeration industry.
