Our dome-loaded sanitary back pressure regulator can accurately control the differential pressure across a membrane in a wide range of flow rates.

Equilibar offers a flow control valve that can dose at low and medium flow rates while also accommodating very high CIP flow rates

Traditional flow control valves have difficulty in injection and metering applications where the downstream pressure is widely varying.

For demanding dosing applications, a back pressure regulator can isolate the control valve from downstream pressure variations.

The key to the ultra wide range of flow comes from the high resolution of the Equilibar BPR coupled with the Equilibar QPV.

A benefit of using a back pressure regulator to control the flow of a pump is that it is easily manufactured from materials compatible with process fluids.

While MFCs are a great solution for laboratory flow control and have accuracy as high as 0.5% of reading, they have limitations that Equilibar can address.

Maintain stable output flow rate downstream of positive displacement pumps such as gear pumps, lobe pumps and diaphragm pumps.

These schematics show some of the applications that can be used to accomplish computer automation of flow rate.

Equilibar BPRs have ultra high resolution, zero hysteresis, and zero dead-band. This can be useful for alternative flow control.

The Equilibar precision back pressure can be used as an alternative to traditional flow control valves in certain applications requiring very high resolution and zero dead-band.
