MRC Global stocks over 50 million Euros in valves and flow control products. Our experienced employees have a proven track record in the selection, supply, service, support and delivery of the world’s leading brand names in the valve industry. MRC Global works hard alongside our customers reviewing specifications and creating valve solutions that deliver a high standard of performance, safety and quality. Our strength is the diversity of valves in our stock and our ability to source specials efficiently and cost-effectively. Most locations have machine workshops which allow for in-house modifications, which save our customers time by not having to source from multiple locations. We have ISO 9001:2008 accreditation at all operating sites and ensure the valves we source meet industry and customer specifications. MRC Transmark is able to supply a comprehensive range of cast and forged gate, globe and check valves, bellowed sealed gate and globe valves, ball valves, butterfly valves and metal seated valves.

Multi-Turn Valves:
  • Gate
    Multi-Turn valves are opened and closed by turning a wheel more than 360 degrees. Two primary examples of this type of valve are the gate valve and globe valve. To open and close the gate valve, multiple turns of the handle are required to turn an acme threaded nut on the threaded shaft of the valve causing it to open or close by raising or lowering the gate. These valves operate in one of two positions, open or closed, and are not recommended for throttling. The globe valve, on the other hand, opens and closes incrementally and is used to modulate flow levels, pressures, or temperatures. Both the gate valve and globe valve are commonly used in downstream applications. MRC Global maintains large inventories of gate valves and globe valves in materials such as carbon steel, stainless steel and special alloys to serve the needs of the refining, petrochemical, chemical and process industries.
  • Globe
Butterfly Valves:
  • High Performance
    Butterfly valves typically have a circular shaped disc that rotates to open or close the valve, thus controlling the flow of material through the valve, with a quarter-turn function, using a handle or gearbox. MRC Global maintains an extensive inventory of resilient seated butterfly valves, high performance butterfly valves, and triple offset butterfly valves to service all major industrial sectors. Our inventory includes butterfly valves in carbon steel, stainless steel and alloy materials.
  • Lined
  • Resilient Seated
  • Triple Offset
Ball Valves:
  • Cryogenic
    Ball valves open and close with a quarter-turn function, using a handle or gearbox and are commonly used in the exploration, production, gas utility, chemical and industrial sectors. MRC Global is one of the largest suppliers of API 6D ball valves to the transmission, pipeline gas gathering, tank farm storage, and utility sectors. MRC Global also stocks extensive size ranges, multiple configurations and most body and trim types of floating and trunnion ball valves. Both Floating ball valves and trunnion ball valves are offered in full and reduced bore sizes.

  • Lined
  • Resilient Seated
  • Trunnion
  • Top Entry
  • “V” Port
Plug Valves:
  • Lubricated
    MRC Global is a leading distributor of plug valves to the energy and industrial markets. Plug valves are named for the cone-shaped, plug-like device that controls the flow of fluid through the valve. Rotating the handle a quarter turn or turning the handwheel on the gearbox starts or stops the flow of fluid by introducing the through bore or solid portion of the plug. The plug valve is ideal for gas transmission, gas utility and chemical applications, and is offered and stocked in elastomeric lined or full metal construction.
  • Non-lubricated
  • HF Acid
  • Lined
Check Valves:
  • API6A / API6D
    A check valve design only allows fluid to flow one direction. It is generally used in conjunction with other types of valves and will close automatically when line pressure is lost, thus it has no handle to turn on and off. This feature makes check valves ideal for preventing plant and equipment damage caused by excess backflow, a necessity across all streams of the energy industry. Check valves are stocked in several body configurations and materials.
  • Lift Check
  • Piston Check
  • Swing Check
  • Wafer Check
  • Y Pattern Check
Specialty Valves:
  • Bellow seal
    MRC Global offers a wide variety of specialty valves capable of handling the most severe services: cryogenic, superheated steam, volatile and corrosive fluids, erosion, high pressure drops, vibration, cavitation, flashing and other abrasive services. Diaphragm valves, needle valves, knife gate valves, pinch valves, cryogenic valves and many others are available in carbon steel, stainless steel and specialty alloys.
