Safety valves made of stainless steel, angle-type with flange connections
The series of flanged safety valve 455 captivates with its consistent concept of capacity, function and design. The high capacity of the entire series from DN 20 up to DN 100 is unique in the sector of flanged safety valves. By using exclusively high-quality materials with outstanding media resistance and the option to secure the tightness towards the atmosphere on a high level with a backpressure compensating bellows, this safety valve is suitable for nearly all applications. The pressure range extends from 0.2 to 40 bar and by using metal to metal sealing; even very low temperatures of down to -270 °C can be achieved. Also extremely high temperatures can be applied up to a limit of 400 °C. The valves are available with flanges, according to DIN EN 1092-1 PN 40 on the inlet side and PN 16 on the outlet side and optionally with a lifting lever and a proximity switch for the display of the valve opening.
For the protection of:
