CBP-3 Series Back Pressure Control Regulators

Compact Stainless Steel Back Pressure Regulators

The CBP-3 is a compact back pressure regulator that employs many of the same features found in the time tested design of the BP-3 Series back pressure regulator. This regulator is designed to allow the construction of compact and sophisticated analytical instrumentation where the optimum in back pressure control is required and space is at a premium.
