Optimized internal volume

JB series of back pressure regulators from LowFlow are designed for gas use and to control the back pressure in applications which require very high pressures and low flow rates. Typically JB Series will be used in research applications or sampling systems for corrosive and speciality gases.

Inlet pressures are suitable for up to 68 bar (1000 PSI). Six different spring rates are configurable to the JB series which will allow back pressure control down to as little as 0.3 bar (5 PSI) or up to 52 bar (750 PSI) dependant on spring rate selected.

Various Cv ranges are also available from 0.05 up to 0.35.

Instrument build options include panel mount, captured vent, locking wire, lockout device or tamper proof systems.
