DonadonSDD’s KRD reverse acting rupture discs are critical safety devices that protect your industrial plant by preventing sudden pressure build-ups. Reverse acting rupture discs have a convex disc camber that remains unaltered under operating pressure until reverse pressure is reached and this can ensure long service life. DonadonSDD KRD rupture discs uses advanced sector technology and provide targeted and precise protection in the most demanding applications making DonadonSDD KRD rupture discs an optimal safety choice for plants dealing with extreme conditions. Its specific design makes the KRD ideal to offer pressure protection to equipment where Full Liquid fluid is present.
Keyfeatures & technical benefits
State-of-the-art Design:
Particularly suitable for the Pharmaceutical, Food, and Biotechnology industries, and represents the advanced for these sectors.
FDA-Certified Gaskets:
PTFE gaskets, which are certified in compliance with FDA and USP class VI, 3-A, and Eu 10/2011 regulations, facilitate installation in Clamp fittings (sanitary, Tri-Clamp, Tank Connection).
Hygienic Applications:
Designed to meet the high-quality standards required by 3-A SSI, GMP and MOCA to ensure public health through hygienic equipment.
High Certification Standards:
Our KRD rupture discs have achieved the highest certifications, including ASME XIII (UD STAMP), PED 2014/68/UE (CE STAMP), ATEX EX II 2 GD (CE STAMP), PER 2016 UK Statutory Instruments 2016 No 1105 (UKCA STAMP), and CU TR 032 (EAC STAMP)
Advanced Technology:
KRD rupture discs obtained using our patented Laser NS NanoScored technology are reverse-acting discs with micro-scored calibrated sections opening around the circumference, reducing the risk of petal detachment.
Reliable Performance:
Withstands thousands of cycles without compromising their reliability, with ratios up to 95% between operating and rupture pressure.
Rapid Non-Fragmenting Rupture:
The disc opens completely in a few milliseconds along a circumferential line scored on the downstream side of the disc, thus preventing fragmentation from forming.
Versatile Design:
Suitable for presence of 100% liquid, cycling, and pulsating conditions without reducing safety margins.
Corrosion-Resistant:
Wide range of materials and thickness options; PTFE or PFA lining (FDA Approved) available for added protection.
High Pressure/Vacuum Resistance:
Does not require vacuum support, avoiding restrictions in the discharge area; capable of resisting high backpressures.
