STUVENT rupture disc

• Suitable both for dust and gas explosions
• 100% efficiency
• Usable with underpressure and overpressure
• Simple and fast mounting
• Also available with isolation in high temperature version
• ATEX certified

A simple and affordable rupture disc

If the location and environment allow it, a traditional rupture disc (a thin metal membrane that opens at a specified pressure) is a simple and very economical solution.

Explosion venting with a STUVENT rupture disc

A STUVENT rupture disc has some important advantages:

• Suitable both for dust and gas explosions
• 100% efficiency
• Usable with underpressure and overpressure, depending on type
• Smooth interior surface eliminates 'dead corners'
• Integrated gasket for simple and fast mounting
• Construction is such that projections at opening are avoided

The STUVENT rupture disc is an ATEX ‘safety system’ for the venting of explosion pressure. Its efficient functioning as a safety system depends on the right venting area and the correct positioning on the process equipment. See also EN 14491.

Functioning of the STUVENT rupture disc

STUVENT rupture disc for easy venting

The functioning of the STUVENT rupture disc is remarkably simple: when the preset opening pressure is exceeded, the disc opens on the three pre-cut sides. The fourth side is not pre-cut to avoid it flying away.

STUVENT rupture disc with position report

The STUVENT rupture disc is also available with a rupture sensor. This can be used as a break sensor for the rupture discs, but also as an interlock switch.

The advantages of the EBS sensor are countless:

• Very simple and quick installation
• No false alarms, unlike classical break wires
• Functionality can be tested without disassembling or switching off
• Detects both rupture discs that have opened to the outside as rupture discs that have been sucked in
• Not integrated with the rupture disc, therefore universally applicable. The EBS also fits every already installed rupture disc or explosion door (regardless of brand)
• ATEX certified for dust and gas Ex zones.

A rupture disc in different shapes 
and for different processes and installations

Round or rectangular STUVENT rupture disc

Depending on the application, the rupture discs can be supplied in various models:

• Type KE: if only relatively small pressure variations are present, a simple flat rupture disc is sufficient.
• Type KER: to facilitate mounting, the KE can also be supplied with reinforced edges for mounting without a counter-frame.
• Type KEW: for mounting on curved surfaces (such as a silo wall), curved rupture discs with a specific radius can be supplied.
• Type GE: in the case of large pressure changes and/or significant underpressure, it is advisable to install a convex rupture disc. Depending on the size and the model, the GE type can be used up to an absolute vacuum.

STUVENT rupture disc for different processes

• The STUVENT rupture disc can be used for dust, gas and hybrid mixtures.
• For processes with both overpressure and vacuum.
• The STUVENT rupture disc is made of stainless steel.
• Various gaskets are available: for high temperatures, for food and hygienic environments and with FDA approval.
• To avoid problems with condensation, an insulation layer up to 100 mm thick can be applied to all disc types.

STUVENT rupture disc for any installation

• Installation is possible in all positions.
