Badger meter control valves, available in the UK through Pump Engineering, are making a contribution to oil extraction in ultra-deep oil wells where the ability to overcome the difficult challenges associated with these applications, such as extreme pressures, wide flow ranges and very low temperatures, is extremely important. The Badger Valve Co. was challenged to manufacture 1in valves that could handle ethylene glycol at flows up to 220ltr/mn at 700bar. These valves were successfully deployed in deep water oilfields in the Eastern Gulf of Mexico where pressures are relatively high and temperatures relatively low and therefore the risk of hydrates forming is high. The Badger range includes models ranging in size from 0.25 to 2in, capable of operating in temperatures from -270C to +800C, with CV’s from 0.000018 to 2.5 and rangeability from 50:1 to 15:1. They can be supplied as standard in 316 stainless steel with stainless steel or Stellite trims, although alternative materials such as Monel, Hastelloy B and C, titanium and zirconium, can also be specified.
