Rupture disc
Rupture discs from Continental Disc Corporation offer reliable overpressure and underpressure protection - wherever safety, process integrity and precise pressure protection are required. They react quickly and reliably - regardless of the medium - and are therefore equally suitable for the immediate depressurization of gases and liquids.
The product range includes Forward-Acting and Reverse-Acting bursting discs, the hygienically certified HPX series, protective accessories and indicators for safe monitoring. The products are used in industries such as pharmaceutical, food, chemical engineering, energy and pulp/paper.
The advantages are fast response, media-independent operation, high hygiene standards and effective protection against damage to facilities.

Specialized Rupture DiscsPOS-A-SET® Rupture Disc
Relieve ultra-low vacuum or positive pressure conditions with the highly accurate, bidirectional POS-A-SET rupture disk. Our double-acting design allows the POS-A-SET to do the work of two rupture disks with just one installation point. It relieves low positive pressure (as low as 1 inwc) with a girdle and knife-blade assembly on one side, while slightly higher negative pressure is relieved from the other side with perforations and a pre-cut section. Looking for the CAL-VAC rupture disc? Nearly identical to the POS-A-SET rupture disc, the CAL-VAC relieves ultra low-pressure in the negative direction - the inverse of the POS-A-SET's ultra-low relief in the positive direction.Continental Disc Corporation -

Learn more about blasting caps
What is a blasting cap?
A bursting diaphragm is a reliable safety solution to protect industrial facilities against overpressure and vacuum. The component consists of a thin metal diaphragm designed to burst at a precisely predetermined pressure.
Rupture discs are widely used in piping systems, tanks and process equipment in the chemical, energy, food and pharmaceutical industries, among others. They are available in several dimensions and pressure classes, making them adaptable to many different applications.
How does a blasting cap work?
The bursting diaphragm acts as a passive protection that is activated when a critical differential pressure is reached. When the diaphragm ruptures, the system is immediately relieved and the risk of damage to equipment or leakage of hazardous media is minimized. Since the rupture disc has no moving parts, opening takes place in a few milliseconds and the function is both predictable and stable over time.
Advantages of blasting plates
Bursting discs offer several advantages over traditional safety valves in the right applications. They provide very fast and accurate pressure relief and are completely tight during normal operation, preventing unwanted leakage.
The simple design means minimal maintenance and a long service life, often several years without the need for replacement. In addition, rupture discs are a cost-effective solution that can be used with gases, liquids and mixed media in a wide range of industries.
