【2025 Industrial Automation Updates】Emerson introduces Fisher™ GX bolted valve covers with direct control valves
Thread Content
Emerson has announced the introduction of the Fisher™ GX bolted valve cover direct-acting control valves and actuator systems, designed specifically to control the flow of critical process fluids in downstream oil and gas, chemical, and petrochemical industry applications. When servicing or replacing the actuator, the interior of the valve or the process medium is not exposed to the atmosphere, thereby improving safety and reducing downtime.
The design of the standard valve cover allows the bolts used to secure the actuator to also fix the valve cover to the top of the valve. Therefore, it is impossible to replace or repair the actuator without removing the valve cover and exposing the interior of the valve. Therefore, it is difficult to repair actuators in critical fluid applications.
The Fisher™ GX bolted bonnet control valve uses a separate high-strength locknut to secure the actuator yoke to the bonnet, thereby addressing these challenges associated with critical fluid applications. In this way, maintenance technicians can easily disassemble and service the actuator while keeping the valve cover in place.
This valve is equipped with a pneumatic actuator as standard, but it is also compatible with electric actuators. It can be used with electric actuators from many different suppliers, thereby flexibly meeting the requirements of such actuators.
The Fisher™ GX bolted valve cover control valve expands the existing GX product line, continuing to offer simple size selection through automatic actuator selection and easy configuration. Its compact size also simplifies installation in areas with limited space.
The latest Fisher GX valves feature a design that facilitates access to the actuator, allowing for easy maintenance or replacement without the need to remove the valve cover.
The Fisher™ GX bolted valve cover globe valves and associated actuator systems are specifically designed for critical fluid control applications in the downstream oil and gas industry, as well as in the chemical and petrochemical sectors. This actuator allows for maintenance and replacement without exposing the internal components of the valve or the process medium, thereby ensuring operational safety and effectively reducing downtime.
The design of the standard valve cover features a structure in which the actuator bracket bolts are used to secure the valve cover simultaneously. This design requires that the valve cover be removed first to expose the valve core during maintenance, in order to replace or repair the actuator, which makes it extremely difficult to service the actuator under critical fluid conditions.
The Fisher™ GX bolted bonnet control valve uses separate high-strength lock nuts to secure the actuator bracket to the bonnet, effectively addressing maintenance challenges in critical fluid applications. This design allows technicians to easily perform maintenance on the actuator without removing the valve cover.
The valve is standardly equipped with a pneumatic actuator, and is also compatible with electric actuators. Electric actuators from various manufacturers can be used, allowing flexible satisfaction of different electric drive requirements.
The Fisher GX bolted bonnet control valve represents an extension of the existing GX product line, building on the advantages of easy selection provided by the automatic actuator options and convenient configuration features. Its compact design also simplifies the installation process in spaces with limited space.
