ZW
opens in one direction at defined overpressure + in the other direction at vacuum.
The ZW can be supplied with an integrated SNR signalling unit suitable for use in hazardous areas. When the disc ruptures in either the overpressure or vacuum direction, the SNR gives an open circuit signal to advise of an activation. By combining the principles of the KUB® reverse acting rupture disc with the buckling pin and the three-section design of the ODV forward acting rupture disc, we can offer you a rupture disc that responds at two different but precisely defined burst pressures.
signalling devices
Automated processes use intelligent signalling systems to keep you informed at all times about the status of your entire plant and any faults that may arise. You can even install signalling devices for rupture discs that have already been installed.
Gasket
For all process conditions. For example, for high temperature or sterile requirements.
