Summary: MSA are the world leader in underground fully welded pipeline valves. Their Model K83 TW has been specifically designed and tested for underground service.

MSA Pipeline Gas Valves key features:

  • MSA only use European materials thus guarantee high quality MSA Ball valves are forged material. Forgings provide higher strength, better grain flow and fewer defects than castings All machining of components, assembly and testing is performed in house, no need for sub-contractors, provides complete control over quality and allows faster manufacturing lead times Special adjustment device is fitted as standard to all buried service valves which enables verification of the fully open/closed position, useful when replacing gearbox/actuator after installation Integral forged body covers can be supplied eliminated the need for weld on pups, no need for NDE testing, eliminates ovality allowing alignment into pipeline quickly and easily
  • MSA have developed a unique welding process to ensure 100% welding integrity of body and pup welds Special X-Ray testing process developed for fully welded ball valves by MSA Engineering at their Testing Laboratory. NDE is performed by MSA personnel qualified and certified to EN473
