"The digital transformation of the process industry continues to make operations safer and more productive," said Prayag Vatsraj, Global Product Manager of Emerson's Switchbox. Certified for operation in harsh and hazardous applications, the adaptive DX PST is designed to ensure the integrity of valves, improving overall safety and facility uptime in oil and gas, refinery, chemical, industrial energy and mining applications. To prevent critical failure in upset conditions, the unit will override testing to perform an emergency shutdown (ESD). A safety feature that confirms the valve will fully close and stop the process if an emergency is detected, and the test is activated by simply pressing the local PST button - no additional equipment is required.
The DX PST's partial stroke test ensures the system's reliable function without shutting down the process. The new DX PST integrates seamlessly with existing valves and control systems, giving operators access to critical valve data, trends, and diagnostics that can be used to predict and schedule maintenance. Units provide valuable valve data and diagnostic information, enabling the digital transformation of process applications.
