Research Control SRD smart valve positioners help users comply with fugitive emissions regulations. A key feature of the SRD is its comprehensive valve diagnostics tool that continuously monitors for fugitive emissions from leaks and other releases of gases to help process plants meet the ANSI/FCI 91-1 standard, and comply with EPA emissions guidelines.

C27 actuators can be coupled to any one of several body assemblies or valve body models. They have higher bench ranges that allow for an increase in pressure drop capacities and an increase in flow capacities. Their shorter stem and yoke make the valve assembly more compact, which means the units require less space when installed in gas, oil, water, steam or corrosive liquid transfer systems.

Emerson’s Fisher Fieldvue DVC6200 digital valve controller series incorporates a 4-20mA position transmitter that can also be configured as a discrete switch. The discrete switch is a solid-state circuit that opens and closes based on a user- configurable trip point. The position transmitter is independent of the digital valve controller. DVC6200 communicates with the latest HART 7 standard.
