Reverse-acting bursting discs to protect a refrigeration system from overpressure.
BS Bursting Discs
Bursting Discs are safety devices designed for installation between a 3-way valve and a safety valve. They are being used when a greater tightness is required and to protect the safety valve from damaging effects of the operating medium such as soiling, sticking or corrosion.
Technical Features
- Available in stainless steel
- Selection of body material as per German DIN EN12284, AD2000 Series W
- Working mediums: refrigerants as per EN 378 p. 1, e. g. NH3, R22, R134a; gaseous mediums
- Use of bursting discs is not permitted in a system where the maximum operating pressure is higher than 90% of the low bursting tolerance. Bursting discs are suitable for gases, but not liquids. The burst tolerance is +/- 10% or optionally +/-5%.
