Back Pressure Regulators

A back pressure regulator accurately controls the inlet pressures to any process. Our range covers port sizes from 1/8" to 2" and control pressures from 0.1 bar (2 psi) to 690 bar (10,000 psi) on gas or liquid applications. The designs provide accurate and repeatable shut-off due to the large sensing area and minimised loading on the seating area.
