Controlling Position of a Process Control Valve
This drawing shows Proportion-Air’s electronic pressure regulator controlling the position of a process control valve. Proportion-Air’s electronic regulator pressure ranges available are between full vacuum to one-thousand psig. This shows a QB1 calibrated 3 to 15 psig. Proportion-Air’s I to P (E to P) are closed loop. Supply pressure fluctuations don’t affect downstream pressure. There is a monitor output signal from the on-board pressure sensor available for data acquisition. Mounting position won’t affect its pressure output. Instrument air is NOT required.
