POS-A-SET Rupture Disc

Description

A double-acting rupture disc with perforations and a pre-cut section on one side, and a girdle and knife-blade assembly on the other – the reverse of the CAL-VAC.

Our double-acting design allows the POS-A-SET to do the work of two rupture discs with just one installation point. It relieves low positive pressure (as low as 1 inwc) on one side, while slightly higher negative pressure is relieved from the other. The POS-A-SET’s easy-to-clean flat-seat design reduces product buildup, making it easier to meet FDA requirements.
