The ET134 temperature/ pressure regulators with Cascade Control eliminates wide temperature fluctuations by preventing spikes in pressure caused by changes in process load. The regulator is essentially a pressure regulator reset by temperature changes. Sensors continually reset the pressure setting as the temperature fluctuates. In addition, it uses a vapor tension thermostat to prevent ambient conditions from affecting temperature control.
