How it Works

Equilibar’s back pressure regulators (BPRs) are dome loaded. This means that the pressure setpoint is provided by a fluid that is fed into a chamber on the top (dome) of the regulator. The pressure of the fluid (either gas or liquid) is set by a second regulator called a pilot regulator. The loading mechanism is a supple diaphragm, which is the only moving part in an Equilibar BPR.

Continuous flow chemistry, or flow chemistry, is a popular way to run a process with advantages over batch chemistry. These advantages include more consistent quality, increased efficiency and easy scale-up from R&D to production. Controlling pressure in flow chemistry is important for phase control, residence time, reaction speed and equilibrium management. READ MORE

Level control is a very common process requirement for vessels across a wide range of industrial and research applications. The most common level control configuration is an on/off valve triggered by a level sensor but other methods of level control may be used in certain situations. READ MORE

There two major types of vacuum control devices: vacuum regulators and vacuum breakers. Vacuum regulators work by throttling flow between the vacuum pump and the process in order to control the process vacuum. Vacuum breakers let ambient air into the vacuum system to control the vacuum pressure. READ MORE

A back pressure regulator is a device that maintains a defined pressure upstream of itself, at its own inlet. When fluid pressure at the inlet exceeds the setpoint, the valve throttles open just enough to relieve the excess pressure. Back pressure regulators work similarly to relief valves, but the emphasis is on steady state pressure control instead of on/off actuation. READ MORE

Servo electronic pressure regulators (EPRs) work by using a push valve and a vent valve to maintain the outlet pressure equal to the desired setpoint. A small internal pressure sensor monitors the output pressure and a digital or analog controller adjusts the timing of the push and vent valves to maintain the setpoint. READ MORE
