SAFETY
UP TO 15,000 PSI (1000 BAR)
RUPTURE DISC HOLDERS
For protection from dangerous over-pressurization
rupture discs function in a waterblast system analogous
to the function of fuses in an electrical circuit. When the
system pressure exceeds that of the burst disc, the disc
bursts and allows water to flow out of the holder’s cap,
relieving the system of high pressure.
• May be used as primary and/or secondary relief devices
• Tamper-resistant design
• Discs are quickly and easily replaceable
• Assembly components machined from high quality
stainless steel
NOTE: Burst Disc not included with assembly.
Disc Selection
For primary relief devices, select disc with burst
pressure of approximately 1.2 times desired
operating pressure.
Example
Operating pressure: 10,000 psi (700 bar)
Desired burst pressure: 10,000 psi x 1.2 = 12,000 psi
700 bar x 1.2 = 840 bar
Select 12,000 psi (827 bar) Burst Disc, part no. 51049
For secondary relief devices, select disc with
burst pressure of approximately 1.4 times desired
operating pressure.
Example
Operating pressure: 10,000 psi (700 bar)
Desired burst pressure: 10,000 psi x 1.4 = 14,000 psi
700 bar x 1.4 = 980 bar
Select 14,000 psi (965 bar) Burst Disc, part no. 51050
