Dome Loaded, High Accuracy The Mark 56/560 Series dome loaded back pressure regulator revolutionizes back pressure control by eliminating mechanical springs in favor of precise air loading. This means you can adjust setpoints on-the-fly to match changing process conditions – no more manual spring changes, no more compromise setpoints, no more shutdowns for pressure adjustments. Whether optimizing batch processes, responding to seasonal demand changes, or fine-tuning system performance, you now have complete control at your fingertips. Configure control exactly how your operation needs it. Couple with an I/P transducer for seamless integration with your DCS or PLC, enabling remote setpoint changes and automated pressure profiles. For local control, pair with a Mark 12 loading station or LowFlow JR regulator for precise manual adjustment. This flexibility of this dome loaded back pressure regulator means operators can optimize pressure from the control room during normal operation, while maintenance staff retain local control capability for commissioning and troubleshooting.
