Safety & Relief Valves

Mankenberg Industrial Valves


Safety valves are the ultimate protection device for tanks and pipelines. They prevent pressure limits being exceeded once all automatic control and monitoring equipment has failed.

SV 29L is a spring-loaded normal safety valve with threaded connection and closed spring cap. Component testing for connection sizes G 1/2 and G 3/4 for steam and gases up to 150 bar and liquids up to 40 bar.

    Normal safety valves initially open proportionally up to a pressure rise of 10 %. This initial phase is followed by the full opening of the valve, allowing a large flow of medium. Especially in the case of liquids, the wide proportional range results in a continuous operation. Pressure rise:
  • above 1 bar set pressure: ........10 % up to required valve lift
  • below 1 bar set pressure: .........0.1 bar.
