Angle safety valve with lever

Safety valves open automatically when overpressure occurs in a pressurised system, relieve the medium and keep the system safe. They are used in critical applications such as steam boilers, pressure vessels, gas lines and process equipment.

Operation

  • The valve is calibrated to a specific set pressure.
  • When the system pressure exceeds this value, the spring mechanism responds and the valve opens automatically.
  • When the pressure returns to normal, the valve closes by itself and the system is safe again.

Advantages

  • Prevents bursts and equipment damage
  • Automatic, reliable operation
  • Protects personnel and the environment
  • Economical – especially in low/medium-pressure systems

Applications

  • Steam boilers and reactors
  • Pressure vessels and gas systems
  • Chemical and petrochemical plants
  • Power plants
  • Food and pharmaceutical production lines
  • Refrigeration systems and HVAC applications
