Marston
A complete range of non-reclosing pressure relief devices, from simple conventional designs through composite assemblies to top-of-the-range reverse buckling discs.
The Marston range of bursting discs provides reliable and cost-effective pressure protection for any pressurized system, particularly in chemical, oil and gas, pharmaceutical, plastics and rubber industries. With a broad range of material options and accessories, these can be used as primary safety device to give almost instantaneous pressure protection, in parallel with other pressure safety devices, or also to protect a safety valve against corrosive or viscous process media.
Flat
For low pressures Metals but mainly PTFE and PFA Usually non-fragmenting depending on materials
Reverse Buckling
Dome directed towards process Works in compression Usually non-fragmenting Accepts lower operating range
Forward Acting
'Conventional' The 'original' disc Burst on tension Fragmentation Very high pressures possible
