SRL Reverse-Acting Rupture Disc

SRL Reverse Acting Rupture Disc

This convenient one-piece, single membrane rupture disc is reverse-bulged and perimeter-scored to facilitate opening without knife blades.

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
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
