AI Overview BETA

Pressure Tech BIBS100 is a negative-biased, dome-loaded back pressure regulator with a maximum rating of 50 bar for pressure control. Fine adjustment of its bias spring gives operators enhanced control over process settings and the regulator’s set-up process. Gas processes with large flow requirements suit its CV 2.0 design, which supports applications requiring a large flow.

Balanced main valve design minimises load on the seat and stabilises pressure control
Large sensitive elastomeric diaphragm provides accurate pressure regulation
Seat cartridge access from the regulator base simplifies servicing
Control range: up to 30 bar (435 psi) bias
Design proof pressure: 150% of maximum working pressure
