Discrete Valve Controller Improves Safety

Discrete Valve Controller Improves Safety

Emerson introduced the Topworx DX PST with Hart 7. Units provide valuable valve data and diagnostic information, enabling the digital transformation of process applications.

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.

The device’s partial stroke test ensures the system’s reliable function without shutting down the process. 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. To prevent critical failure in upset conditions, the unit will override testing to perform an emergency shutdown (ESD).

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.
