Yale® high pressure closures are ideal for pipeline, pressure vessel, pig trap, filter and filtration system and manway access applications. With over 60 years of reliable field service, Yale® quick open closures are the industry leader. 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 72" and ANSI classes of 150 to 2500 on most sizes. Closures feature a modified strong Acme threaded cap and hub, 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 or Aflas 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.

Safety First
The most important feature of Yale closures is safety. Preventing serious injuries, or even deaths, is a primary concern to R&M Energy Systems. Pressure alert valves (PAV's), standard on 6" & and larger closures, provide warning of internal pressure. Their threaded design makes Yale closures the safest in the industry. For example, if residual pressure was trapped behind the cap of a Yale closure, it is virtually impossible to open. Even if the warning provided by the PAV was ignored and the cap was somehow rotated, in less than 1/4 turn the pressure would bleed out the backside of the cap. At this point, over 90% of heavy Acme threads would still be engaged.

Detailed safety, operating and maintenance instructions, plus on-site training seminars, are available for field personnel through R&M Energy Systems' Customer Service Department.
