Back Pressure Regulators

These regulators precisely regulate upstream pressure.

 

Premier offers a wide range of back pressure regulators for use in a variety of industries worldwide.

Our back pressure regulators are offered in varying: materials of construction (with varying degrees of corrosion resistance, weights, strengths etc.), sizes (ranging from .7” to larger 8” models), flow capacities, and inlet/outlet pressure ranges. With the flexibility of optional port alignments, port sizes/types, relief and shut off valves, loading styles, elastomers, color anodizing and more, Premier back pressure regulators provide maximum versatility and compatibility for your unique product application.  

If you do not see a standard model that suits your needs, please contact us. We would be happy to help you with a custom design or modification.
