Video: Smart valve positioner designed to operate in a range of environmental conditions

04 May 2022

Emerson has expanded its portfolio of TopWorx sensing and control products, providing intelligence, reliability and versatility to valve control with the release of the TopWorx PD series smart valve positioner.

The PD series adds to discrete valve controller offerings, providing 100% control over valve position and integrating communication via a 4 mA to 20 mA loop signal and HART protocols. Customers can extract valuable feedback through this intelligent communication and can monitor for trends that offer predictive maintenance insights to help prevent costly downtime.

To maximize reliability, the PD series uses Hall effect contactless position detection. Two plug and play alarms that can be configured throughout the full displacement range help improve plant productivity and safety in any process application. The construction of this product line is also designed to withstand a variety of environmental conditions. The PD Series will launch initially with two models: The PD100 forSource: EmersonSource: Emerson general purpose applications and the PD200 for use in explosive atmospheres.

The compact and lightweight design of the PD series delivers a high degree of versatility, allowing for quick and simple installation on rotary and linear actuators in many applications. The same solution can provide precision control on both single- and double-acting actuators. An LCD screen allows operators access to device status and optional magnetic key technology allows operators to set all functions of the device without removing the cover in the field. Low air consumption and fast response deliver efficient operations, providing a single solution for both standard and heavy-duty conditions.

The TopWorx PD Series is built to the same industry-leading standards as other proven TopWorx products to deliver exceptional value and trusted performance for demanding applications. The PD Series is suitable for use in oil and gas, chemical, industrial energy, on-site utilities, power generation, pulp and paper, waste and wastewater, and food and beverage applications.
