How it works

Spring-loaded relief valve

Spring-loaded relief valve: Below set pressure
Below set pressureThe spring holds the disc on the seat.
Spring-loaded relief valve: At set pressure
At set pressurePressure lifts the disc and vents through the outlet.

The number that matters

Nominal pressure

16bar

The pressure class of the valve body at 20 °C. Working limits depend on the medium and its temperature.

Applications

Media and industries

  • Water
  • Air
  • Steam
  • Petroleum Products
  • Fuel Oil
  • Heating Systems
  • Water Supply
  • Oil And Gas Industry

A spring safety valve is a device used to automatically reduce excess pressure in systems, preventing it from exceeding established safety limits. It consists of a valve, a spring, and a setting that determines the valve's opening pressure.

When the pressure in the system reaches a certain level, the spring activates, opening the valve and allowing excess pressure to escape, preventing damage to equipment or the system due to overpressure. Spring safety valves are widely used in various industrial and technical systems to ensure their safety and reliability.
