Reverse Domed With Knife Blades Rupture Disk

Pressure acts on the convex side of rupture disk. At its burst pressure, the disk reverses with the knife blades on the upper holder cutting it . Types Reverse Domed With Knife Blades Rupture Disk (YD): The disk is made up of sphere solid metal with burst pressures ranging from 0.05MPa to 12.0MPa.Reverse Domed Rupture Disk With Knife Blades (YDV): The disk consists of brackets and corrosion-resistant seal membrane with burst pressure ranging from 0.001MPa to 0.1Mpa, and suitable for super-low or vacuum vessels.Features Optimum fatigue resistance for pressure pulsating or cycling conditionMaximum operating pressure up to 90% of the minimum burst pressure Withstand full vacuum condition without vacuum support (YD type)Non-fragmenting design, suitable for safety valve isolation.Designed for gas, dust service, and not suitable for no gas space equipmentNot suitable for high burst pressure conditions
