SRL Reverse Acting Rupture Disc

SRL Reverse Acting Rupture Disc

Scored, Reverse-Acting, Low Burst Pressure

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 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
