Explanation
- The PVCFS (Composite Flat Square) / PVCFR (Composite Flat
Rectangular) 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 fl uid in the process.
The support panel supports the whole panel.
- It is the type broken by the internal pressure of fluid 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)
