Why it is specified
The valves nobody looks at until the day they matter. Sized on the relieving case rather than on the line, and quoted with the set pressure, the required capacity and the back-pressure assumption stated.
Typical applications
- Compressor protection
- Pump discharge non-return
- Thermal relief on isolated lines
- Vessel and boiler protection
Options and executions
- Bellows for back-pressure
- Lifting lever, plain or packed
- Soft seat for tight shut-off
- Test certificate with the set pressure
