Zook ZVac-ZPos Bursting Disc – Ultra Low-Pressure

The Zook ZVac-ZPos Bursting Disc Series offers bi-directional rupture disc and holder assemblies designed to manage ultra-low pressures. These discs protect processing, fermentation, storage tanks, and low-strength vessels from both vacuum implosion and over-pressure failures. The Z-VAC and Z-POS models are engineered for ultra-low pressure relief, with settings starting at 1 inch (25 mm) of water column. They feature replaceable knife blades for the Z-VAC model and a dual-acting design for the Z-POS model. Both models ensure non-fragmenting openings and can be customized to meet a broad range of non-standard specifications and applications.
