Features
03Operation
- 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
