Overview
  • Safety & Relief Valves

    Valves for safeguarding against impermissible overpressure or for discharging excess volumetric or mass flows from pressure vessels and pipelines in the fields of food and pharmacy sanitary sectors and Oil & Gas production, maritime engineering etc.


Spring-loaded safety valves can be used as fittings with a safety function in pipelines and on pressure vessels.


If the pressure before the safety valve reaches the set opening pressure, the valve reacts. Depending on the pressure increase, a small amount of the medium will be discharged initially. If the pressure increases further, the valve opens and discharges more medium.

Different pressure increase curves are permissible, depending on the medium (compressible or incompressible) and the type of valve (normal or full-stroke safety valve).


If the pressure before the valve sinks below the opening pressure, the valve begins to close. Different pressure decrease curves (closing pressures) are permissible, depending on the medium.
