lachnels GROUP -    A W SAFE-SHEAR™ Burst Disc Technology PRECISION BURST DISC & PRESSURE RELIEF SOLUTIONS Technetics offers high precision burst disc and pressure relief solutions for a wide variety of applications. Our products are designed to fit your exact standards and protect your system from high pressure and high vacuum. Our SAFE-SHEAR™ burst disc assemblies are currently protecting diverse systems, from ground-based vehicles to military and space applications such as the V-22 Osprey, numerous satellites such as the Hubble Telescope, Mars Global Surveyor, Gravity Probe B, WISE and International Space Station. We have also produced burst disc relief valves for the Ares and Orion programs, the Space Shuttle, and a variety of current international space vehicles. Products are suited for extreme conditions such as hard vacuum, high pressure, cryogenic and high temperatures. Technetics also provides full analytical, design and test support. DESIGN FEATURES • Materials - Aluminum - Steel - Nickel Alloy • Transport aircraft • Human & autonomous space vehicles •    Aircraft fuel systems •    Space launch vehicles •    Sensitive rail cargo OPERATING PARAMETERS • Burst pressure setting range from 1 psid to 10,000 psid with +/- 1% accuracy [.07 to 689 bar / 7 to 68,950 kpa] • Operating temperatures from -452°F to > +1000°F [-271°C to > +540°C] • Not susceptible to performance degradation over time due to pressure cycles and vibe/shock exposure unlike frangible style rupture discs • High level of accuracy with rupture pressures of ±1% full scale • Burst setting 100% verifiable & adjustable by nondestructive testing • Achieves leak tightness <1.0x10-9 sccs, considerably better than pressure relief valves alone • Allows continuous pressure cycling operation up to 95% of set burst pressure • Able to withstand high shock & vibration levels; does not cause premature rupture or reduced life • Suited for extreme conditions such as hard vacuum, high pressure, cryogenic & high temperature • Offered with an integrated precision pressure relief valve for dual-redundancy • No leakage to atmosphere • Designed for non-fragmentation • Low burst & very high burst pressure capability • Can withstand the vacuum of space • Life of platform capability •    Suitable for highly volatile media •    Launch/Abort/Random vibration resistance • Weight savings of 50-80% compared to competing systems TECHNETICS GROUP EnPro Industries companies 1700 E.
