Product information
KSRRK Rupture Disc – Reverse Dome Shear Type Pressure Relief Device
Protecting industrial pressure systems from excessive pressure is critical for ensuring operational safety and minimizing equipment damage. The KSRRK Rupture Disc is an advanced Reverse Dome Shear Type pressure relief device designed to provide fast, reliable, and maintenance-free overpressure protection for gas, vapor, and liquid applications.
Compared to conventional rupture discs, the KSRRK offers improved handling, excellent corrosion resistance, and outstanding performance under vacuum, back pressure, and pulsating pressure conditions.
THEGIOIVAN.NET supplies genuine KSRRK Reverse Dome Rupture Discs in a full range of sizes, pressure ratings, and material options for industrial applications worldwide.
What is the KSRRK Rupture Disc?
The KSRRK Rupture Disc is a non-reclosing pressure relief device that instantly releases excess pressure when the system reaches its predetermined burst pressure.
Its reverse dome shear design delivers:
- Instantaneous pressure relief
- Leak-tight sealing
- Maintenance-free operation
- Long service life
- Accurate burst pressure
- Excellent fatigue resistance
Reverse Dome Shear Type Design
The KSRRK features an advanced Reverse Dome Shear Type construction.
The disc is installed inside a standard FDC holder, with the disc and knife integrated into a single assembly.
When the preset pressure is reached, the reverse dome inverts and is sheared by the knife ring attached to the upper disc, providing rapid and clean pressure relief without generating fragments.
This integrated design also makes installation and replacement easier than the conventional KSRR model.
Key Features
High Safety Performance
The reverse dome shear mechanism provides highly accurate burst pressure and exceptional operational reliability.
Superior Corrosion Resistance
Available in numerous corrosion-resistant materials including:
- Stainless Steel
- Hastelloy
- Monel
- Nickel
- Titanium
- Tantalum
- Duplex Stainless Steel
- Special Alloys
- Aluminum
Suitable for aggressive chemical and industrial process media.
Excellent Performance Under Vacuum and Back Pressure
The KSRRK is specifically designed for demanding operating conditions:
- Back pressure
- Full vacuum
- Pressure pulsation
- Cyclic pressure applications
No vacuum support is required.
Wide Operating Temperature Range
Designed to operate reliably between:
-200°C to 600°C
making it suitable for both cryogenic and high-temperature applications.
High Operating Ratio
The KSRRK offers a maximum continuous operating ratio of:
90% of the burst pressure
allowing efficient system operation while maintaining a high safety margin.
Easier Installation and Maintenance
Compared with the KSRR model, the integrated disc and knife structure simplifies:
- Installation
- Inspection
- Replacement
- Maintenance
resulting in reduced downtime and lower maintenance costs.
