Two-Way Tank-Safe dual-pressure rupture disc acts as a single design for both positive and negative pressure protection.

The unique construction of this disc comprises a slotted top section, seal membrane and vacuum support. The rupture disc can withstand the same pressure on both sides of the disc (2WS) or differing pressure on each side (2WD).

The holderless design makes this bursting disc ideal for applications where a rupture disc holder is not desired or needed. The non-fragmenting disc offers good life-cycle resistance and excellent relief valve isolation. Installing this disc can therefore contribute to keeping ongoing maintenance costs down.

We supply the Two-Way Tank-Safe bursting disc with a suitable gasket to allow for direct installation between industry-standard flanges.
