Emerson Announces Two Valve Products


Emerson recently introduced a new valve system and a controller that provides detailed valve data and diagnostics.

AVENTICS valve systems with OPC UA


Emerson recently announced that its AVENTICS Series Advanced Valve system with Advanced Electronic System (AES) Profinet and Ethernet/IP is now available with preinstalled Open Platform Communications Unified Architecture (OPC UA) functionality, making it the first and only valve system to offer this directly integrated capability.

The AES helps users solve interoperability challenges and access data more easily while the integration of the digital twin can improve productivity and efficiency. A valve system with integrated OPC UA functionality simplifies communication with upper systems, since data and analytics are received via the valve system and communicated directly to upper systems.

OPC UA functionality also expands the connected capabilities of the valve system itself, making it easier for users to digitally transform. When organizations undergo digital transformation, key protocols such as OPC UA embedded in technologies enable device monitoring and machine connectivity when sending data from a valve system to an upper system. The AES is simple to integrate and connect to new or existing applications and machines and provides easy access to data and analytics without changing the programmable logic controller.

Discrete valve controller

Emerson recently introduced the TopWorxTM DX PST with HART 7.

The unit provides 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 DX PST’s partial stroke test ensures the system’s reliable function without shutting down the process. A safety feature confirms that the valve will fully close and stop the process if an emergency is detected. 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.

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.

The HART protocol, the specifications of which are owned by the FieldComm Group, builds another layer of information that ensures data, trends, and diagnostics are monitored and tied into the Industrial Internet of Things.
