Back Pressure Regulators

A back pressure regulator or valve accurately controls the inlet pressures to any process. Our range includes all of the design features of our other product ranges and covers port sizes from 1/8" to 2". Our back pressure regulators control pressures from 0.1bar (2psi) to 690bar (10,000psi) on both 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. Choose from the options below or email sales@pressure-tech.com for selection advice.
