MRC Global has been providing automated valves for more than 20 years, evolving from a simple bolt-up, quarter-turn shop into an advanced, fully integrated quarter-turn, multi-turn and linear automation provider with facilities worldwide. The combination of our global strength and our local, technical service simplifies automation maintenance by enabling MRC Global to become the single point of contact for all aspects of our customers’ automation needs.

MRC Global represents the premier valve automation lines in the industry. We provide our customers with everything from simple on-off packages to throttling applications, high pressure gas systems, over pressure protection and emergency shutdown assemblies. Our qualified, technical staff will customize your valve automation requirements to your unique product specifications and identify the most efficient solution for your needs.

Electric Actuators:
  • Fail-safe
    Electric actuators are typically used in the upstream, midstream, downstream and waste water applications and use a low or high voltage, electrical input to open or close all types of valves. Electric actuators offer optimum control characteristics and are easily installed on all types of valves.
  • Modulating
  • On-off
Fluid Power Actuators:
  • Electro-Hydraulic
    Fluid powered actuators utilize hydraulic fluid to operate the actuator and can be either self-contained or gas assisted. Fluid power actuators are typically used in upstream and midstream applications in safety critical situations on very large diameter valves when there is limited or no air supply. A key feature of these valve automation products is that fluid power actuators can have a built-in energy source allowing the valve to be closed completely if power is lost as an added safety measure. In other applications if a hydraulic power unit is available, the size of the actuator compared to a pneumatic actuator will be downsized by a factor of roughly half.
  • High Pressure Gas Systems
  • Piston
  • Rack & Pinion
  • Scotch Yoke
  • Spring Diaphragm
  • Vane
  • Water-Hydraulic
Manual Actuators:
  • Spring-Return Handles
    Manual actuators are commonly used across all industry sectors and are typically utilized on large valves to assist in opening and closing of the valve. Manual actuators are, as their name implies, powered manually by the operator but allow the valve to be opened and closed with much less force than would typically be required. This decrease in required force creates safe work environment when operators need to open or close a large diameter valve.
  • Gear Operators
  • Valve Indicators
  • Switches
Limit Switches:
  • Mechanical
    A limit switch is a valve automation accessory. They can be used with various types of actuators to remotely identify whether a valve is open or closed. The limit switch is mounted on the actuator and communicates electronically with the facility’s process control system. Limit switches can help identify problems in the valve automation system before potentially dangerous and costly accidents occur.
  • Proximity Type
  • Digital
    Positioners are a valve automation accessory designed to control the position of the valve. Positioners allow the operator to remotely open or close an automated valve by varying degrees using either a pneumatic or electrical signal. This accessory is commonly used in all flow control applications but is especially applicable for situations where precise control over the varying degree of fluid that should be allowed through a valve at one time.
  • Electro-Pneumatic
  • Pneumatic
Network Capabilities:
  • AS-i
    MRC Global offers many networking solutions for our customers’ flow control needs. These networking systems allow the connection of multiple control valves on one loop so that the operator can communicate instructions to an entire chain of automated valves instead of on a point-to-point basis. This process can create significant cost savings during the installation process and allows for increased functionality. Networks of this type are predominantly used in downstream applications, where there are multiple automated valves in a relatively small geographic area.
