About ORTON

IMI Orton is an international leader in the manufacture of triple offset metal-seated valves, large diameter double-eccentric butterfly valves and concentric rubber-lined valves, for on-off and control service. We have over 50 years experience of designing customised valve solutions for our customers, combining efficiency and reliability with the highest safety standards for use in extreme operating environments. 

Critical applications

• Oil & Gas
  Orton valves have proved their long-term performance and reliability in both on- and off-shore facilities where tight shut-off isolation and modulating features are essential.  Orton products and specialists have become real partners to customers operating in harsh environments and critical service.

• LNG liquefaction plants & terminals
  IMI Orton valves are in use in LNG (liquefied natural gas) Liquefaction plants and regasification terminals worldwide. Customers select Orton for the wide range of technical solutions they can offer, and for their state-of-the-art testing facility, which means that every valve is fully tested before it is supplied. 
  
  

• Petrochemical industries
  With a very wide range of valves ranging from 2” to 120”, IMI Orton valves are widely installed in petrochemical plants around the world. PTA plants with process licensed manufacturers have approved IMI Orton products, and regularly install IMI Orton valves to guarantee top performance and easy maintenance. 

• Desalination plants
  Orton valves help customers operate desalination plants efficiently and reliably. Orton valves protect the pumps in the desalination process area, and the perfect sealing and modulating capability of Orton valves is now widely recognised by plant operators. Orton also offer customers an ongoing maintenance programme, to ensure trouble-free performance for years to come.

Key technologies

• Triple eccentric design prevents wear and leaks, increasing service life
  IMI Orton’s unique triple eccentric design eliminates friction between the disc seal ring and the seat in the body, preventing wear and tear and leakage. MV-series valve discs include a laminated metal seal ring, composed of alternating layers of corrosion-resistant alloy and composite graphite. Each lamination provides an independent seal, improving long-term sealing while also allowing lower operating torques. For high temperatures and more severe applications a hardened, non-laminated seal ring is available. 

• State of the art testing facility 
  Orton in-house testing facility allows them to test the capabilities of valves up to 120” in size. Orton can pressure test to ASME Class 2500, and temperature test from cryogenic to high temperatures (-196°C to +700°C).
