Closure Doors
Yale high pressure closures are ideal for pipeline, pressure vessel, pig trap, filter and filtration system and manway access applications. Yale QOC closures were the first to include a threaded design for unparalleled safety and operating ease. With state-of-the-art manufacturing, outstanding engineering, superior quality control procedures and complete service after the sale. Yale Fig. 500 & Fig. 500R closures are the smart choice for productivity, durability and safety. Yale closures are manufactured in diameters from 2" to 76" and ANSI classes of 150 to 2500 on most sizes. Closures feature a modified strong Acme threaded cap and sub, along with a custom-molded O-ring seal. Standard O-ring material is 70 durometer (Nitrile) Buna N, with optional Viton® (FKM) or Ethylene Propylene trim O-rings also available. Pressure alert valves (PAV's™) are provided on 6" and larger closures, and are available for 2" - 4" sizes. The PAV allows Yale closures to meet the ASME code requirement of an external, visible pressure warning device.
