- Operates in both gas and liquid applications
- Effective in the isolation of Safety Relief valves
- Withstands full vacuum, without the aid of a vacuum support
- Will sustain cyclic and pulsating pressures as high as 90% of the stamped disc rating or 95% of minimum burst pressure
- If damaged during normal installation, the SRL rupture disc will open at less than 1.5 times the stamped burst pressure
- Special seating configuration allows SRL discs to perform reliably, even under less-than-ideal bolt loading conditions
- Effective in VALVEGUARD protection of expensive Pressure Relief Valves and Safety Relief Valves
