Explanation
- The PVCFC (Composite Flat Circular) explosion vent panel consists of the three
components such as the top panel, the sealing sheet, and the support panel.
- The top panel adjusts the burst pressure of the panel. The sealing sheet in the
middle prevents the leakage from the fluid in the process. The support panel
supports the whole panel.
- It is the type broken by the internal pressure of fl uid with the burst part intentionally
processed by the burst design value.
- It is installed with the gasket between the standard or non-standard companion
fl anges or frames.
Properties
- It is the type suitable to the application of fi ne and low pressure.
- Tefl on (PFA) is mainly used for the sealing sheet. However, various material qualities
can be applied depending on the process conditions.(PFA, PTFE, FEP, SUS316L,
Monel400, Inconel600, etc.)
- The various material qualities such as non-asbestos, Tefl on, silicon, rubber, etc. are
used for the gasket.
- It can endure vacuum by applying the vacuum support if needed.
- The panel rupture can be monitored in the control room by applying the alarm
sensor system. (Optional)
