SPEC SHEET
MORE BODY STYLES, MATERIALS OF CONSTRUCTION AND BURST PRESSURES AVAILABLE UPON REQUEST. PLEASE CONTACT US WITH ANY SPECIAL REQUEST.
Rupture disk valves provide a reliable method of
over-pressure protection for sample cylinders and systems.
· Rupture disks are easily replaced or switched to change the burst pressure.
· The rupture disk holder is threaded into an integral port in the valve body and seals the rupture disk against the body utilizing a PTFE washer.
· All Alta Robbins 314 Series accessories and options may be added to Rupture Disk valves.
The nominal rupture disk burst pressure should be at least 40% higher than the system operating pressure. Rupture disk burst pressure will be reduced by pulsating pressures, elevated temperature, and internal or external corrosion. In corrosive applications, regular inspections or pressure tests are necessary.
Use of this rupture disk in vacuum or alternating vacuum/pressure applications may cause premature disk failure. When vented, the rupture unit presents a potential danger caused by noise and escaping pressure, chemicals or fragmented particles.
The complete Rupture Disk Assembly consists of the disk, washer & holder. Each holder is etched with the nominal burst pressure and each disk is color coded for identification.
