RUPTURE DISC HOLDERS
For protection from dangerous over-pressurization,
rupture discs function in a waterblast system similar to
the function of fuses in an electrical circuit. When the
system pressure exceeds that of the burst disc, the
disc fails and allows water to ow out of the holder’s
cap, relieving the system of high pressure.
• May be used as primary and/or secondary
relief device
• Tamper-resistant design
• Discs are quickly and easily replaceable
NOTE: Burst disc not included with assembly.
Making a Disc Selection:
For primary relief devices, select disc with
burst pressure of approximately 1.2 times
desired operating pressure.
Example: For operating pressure of 40,000
psi, desired burst pressure is 40,000 x
1.2 = 48,000 psi. Select 50,000 psi Burst
Disc, Part No. 27484. For secondary relief
devices, select disc with burst pressure of
approximately 1.4 times desired operating
pressure.
