Proportion - Model QB3 Series -High Flow Electronic Pressure Controller
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.
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.
