A Proportion-Air QB2 paired with a Burling Valve process pressure regulator can provide liquid pressure control to support various pressures, temperatures and wetted material requirements. Some of the liquids we can control include hydraulic fluid, caustic soda, sour gas, water and many others.
In this application, a QB2 is piloting a BD series pressure reducing regulator, which is controlling the pressure of water going to a reservoir. The DST series stainless steel pressure transducer is measuring the pressure of the liquid and is providing second loop feedback to the QB2. This feedback becomes the main signal that is compared against the (user supplied) command signal provided to the QB2. The monitor analog output line is connected to the panel meter to display the exact pressure going to the reservoir. The Burling Valve BD series regulator can handle various gases, liquids and steam.
