About the H10P back pressure regulators

Cv: 1·E-0.6 to 0.07  |  Max. Temperature: 300°C  |  Max. Pressure: 690 barg (10.000 PSI)


Equilibar® H10P units are designed to hold a stable pressure up to 690 bar (10.000 PSI). This unit and the U10L unit have the highest maximum pressure control available in the family of Equilibar regulators. When you need higher pressure control, Equilibar is always interested in providing a solution. These regulators can handle liquids, gases, supercritical media, two-phase flow and, within certain limits, even three-phase flow. They are often used in reservoir core analysis applications.

Check out the explanation of the Low-Flow series in this video.


The diaphragms in these units are mostly made of PEEK or stainless steel 316. It often achieves a flow turndown ratio of 1:100.000.

The units are available for applications up to 300°C if they have Kalrez o-rings and metal or polyimide diaphragms.
