Control valves & pressure controllers for automated process control
Do you require optimal precision and repeatability for varying process conditions? Do you operate multiple channels for which you require stable control of 1 or more process parameters? Pressure Control Solutions offers you, with our portfolio of – often customized – pressure controllers, broad experience and expertise in the automated control of process parameters like back pressure, forward pressure, differential pressure, closed volume, vacuum, flow, and level.
Single Valve versus Dual Valve controllers
We divide our automated process solutions and electronic reference pressure controllers into 2 main groups:
- Single Valve controllers:
ERC Series | Single-Valve High-Pressure ERC Series [page under construction]
Bronkhorst PPC | Alicat PCS Dual Valve | DRP-70 EPC | HP-ERC Series
Electronic pressure regulator?
An electronic pressure controller contains a pressure transmitter, a PID controller, and a proportional valve. Depending on which pressure you want to maintain, the valve is placed upstream or downstream of the pressure sensor. The signal from a pressure transmitter is fed into a PID controller. The PID controller will actuate the proportional valve to reach the requested setpoint. To select the right pressure transmitter, PID controller, and proportional valve, parameters like pressure-controlled volume, fill time, flow, nature of the media, temperature, etc. need to be considered. We can help you determine the key factors in your application.
Need some help selecting the right high-pressure controller?
With our expertise and broad portfolio, we are confident we can offer the right pressure controller for your application or industry. Thus, we will enable you to push your process application to its limits: Higher pressure, greater control, higher temperatures & exotic materials are all included in our standard package. Accurate process control is what makes our team flow. No matter how specific, unusual or complicated your application might be.

Automated processes & electronic reference control
With an electronic pressure controller, you can automate any back pressure regulator by supplying an electronically controlled reference pressure. Pressure Control Solutions offers you a wide range of electronic pressure controllers to combine with your Equilibar control valve. What’s more: By adding the right sensor, we can just as well create an automated solution for the control of flow or level – we turn pressure control into Precision Process Control!
Our Product Portfolio in Process Automation
PCS offers different types of reference controllers, each with different characteristics, enabling customization and tailor-made solutions for your application. We offer multiple brands as well as solutions of our own development, independently and where relevant in partnership with Equilibar, and other renowned suppliers like Bronkhorst High-Tech, Alicat, and Specken Drumag. Innovation through collaboration!
No matter how complicated your application, we find you the electronic pressure controller that is right for your process. Our innovative approach to precision process control results in a unique product portfolio.
Electronic reference pressure controllers
Generally speaking, we offer high-precision electronic pressure controllers to control pressure in a small closed volume. This could be any volume that requires constant pressure, regardless of the environmental conditions and/or adiabatic compression or decompression. Combining an electronic pressure controller with an Equilibar back pressure regulator allows creating a stable pressure inside the valve, being a small closed volume. This is one of the most convenient ways to pilot the Equilibar dome-loaded back pressure regulator. By controlling the small closed volume above the diaphragm of the back pressure regulator, the process will stay at constant pressure at all times.
Single Valve Controllers
Within the ERC Series, we offer single-channel electronic pressure regulators as well as multi-channel units. Customers use these units often for high throughput catalytic systems where you can keep multiple reactors under pressure with an Equilibar back pressure regulator. You can use the multichannel units to create a very stable pressure at the reference of a dome-loaded valve.
Dual Valve Controllers
We also offer Dual Valve controllers. The choice of product for your application depends on multiple factors, such as the pressure that you want to maintain at the reference of the back pressure regulator; And whether you have a requirement to minimize gas consumption. For example, if you run a low-pressure application, and you have machine shop air available, you may be less focused on the consumption of air and a single valve controller could be your choice. For higher pressures, minimizing pressurized gas consumption might become more relevant to you and a dual valve electronic pressure controller might be a better fit.
