How to Select the Right Safety Valve
Proper safety valve selection requires careful consideration of multiple factors:
- Set Pressure: Must be equal to or less than the MAWP (Maximum Allowable Working Pressure) of the protected equipment
- Backpressure: Consider both superimposed and built-up backpressure when selecting valve type
- Service Fluid: Steam, gas, or liquid - each requires different valve design and materials
- Temperature: High temperatures affect spring characteristics and seat materials
- Capacity Requirements: Calculate required relieving capacity per API 520 or ASME Section VIII
- Installation Location: Indoor, outdoor, or buried installation affects valve selection
