Pressure Controllers

AMETEK-PMT Model 40 Pneumatic Pressure Controllers automatically position a valve or other final control element to maintain process pressure at the desired set point.

The Model 40 Pneumatic Controller works as a receiving controller that can control any process variable transmitted as a pneumatic signal.

The units are available with control modes of 100% proportional, 200% proportional plus resent, and 300% proportional plus reset, plus rate (PID) for processes with frequent load changes.

They have been tested and meet and exceed the EPA Quad Zero requirement <6 SCFH bleed rate when used on natural gas supply.
