In more fragile applications such as glass-lined reactors which cannot endure high-pressure shocks, low burst pressure rupture discs are required. Traditionally, these low burst pressures were only achievable by graphite rupture discs, which have been proven to:
- Fragment into thousands of pieces, requiring an extensive cleanup process
- Fracture when enduring extreme temperature changes
- Leak emissions
Fike RD540 solves these problems and brings the benefits of our patented G2 manufacturing technology into a low-pressure disc, resulting in extremely high operating ratios, cycle life and lead times.
RD540 features:
- 90% Operating Ratio
- Capable of up to 10,000 cycles with pressures from 1/2 atm. with backpressure to 90% operating ratio
- Operates in gas/vapor applications.
- Can be ordered with an optional FEP or PFA fluoropolymer liner on the process side.
- ASME Certified.
- Effective in VALVEGUARD protection of expensive Pressure Relief Valves and Safety Relief Valves.
