The QB3 pressure control valve is a complete electronic pressure regulating package consisting of two solenoid valves, a control circuit, a pressure transducer, an integrated air pilot operated volume booster and a rugged housing.

  • Full vacuum to 150 PSI (10.34 Bar)
  • Flows up to 30 SCFM
  • Compact, space-saving single unit

The pressure transducer is connected directly to the control pressure so the closed-loop electronics and analog monitor signal can show you what is happening in your process. The pressure sensor signal is constantly compared against the command signal to achieve your desired set pressure. This compact package can be mounted in any orientation (exception: only vertical with full scale pressures below 10 PSI) and is nearly immune to the rigors of the industrial environment. Easy repairs with standard o-rings make this product a great choice.

Like most of our products, the QB3 can be modified in numerous ways to meet the most demanding applications. Customizations may change the price of the product. Get a quote for a product customized to your exact needs using the Request Quote tab below.

QB3 | Single Unit

The QB3 electro-pneumatic pressure control valve is designed for industrial environments. It has an integrated volume booster for increased forward and reverse flow rates of up to 30 SCFM. Because it has such a small footprint, the device can be mounted in most applications in any orientation, and it is immune to shock and vibration (up to 20 Gs). Complete the ‘Request Quote’ form below to tell us about your application. After we receive your request, we will respond quickly and help determine if the QB3 is the best fit. If not, we will provide another product recommendation and a quote.

5 Station Sub-Base Manifold

QB3 | 5 Station Sub-Base Manifold Mounting

While a single unit works for many applications, the option to mount several together is vital for many customers. This versatility is what makes the QB3 such a success. If you require tight pressure control and high flow to multiple processes, the units can be mounted on a sub-base manifold with a shared inlet port and common exhaust port. This way, each unit controls pressure to completely separate processes, but you only have to run 1 supply and 1 exhaust line to the manifold for all. Let us know how many QB3s you would like to manifold mount by submitting the ‘Request Quote’ form below.
