  • Are offered in various styles to adapt to any setting or requirement including:

General-Purpose Diaphragm-Sensing Back-Pressure Regulators
(KBP Series)

The KBP series is a high-sensitivity, general-purpose regulator designed to control back-pressure levels in analytical or process systems upstream of the regulator. The convoluted diaphragm provides excellent sensitivity and set-point repeatability. The metal-to-metal diaphragm seal minimizes the potential for leakage.
