The YDC series are two-way rupture disks that provide vacuum and pressure protection against tank overpressurization or vacuum. Pressure relief is accomplished by the blade holder puncturing this sealing membrane for vacuum, and by the strength membrane of the open seam for pressure relief.
Optional
Protective caps protect the sealing membrane from positive pressure relief.
Bursting cap provides positive pressure relief
Note: This option greatly reduces flow capacity under vacuum conditions, please contact us for other parameters.
