Valves

NLI has extensive valve experience and a great set of vendor alliances to help us solve many valve related challenges for our customers.  Much of our valve experience revolves around obsolescence or the inability for OEMs to deliver products when needed by the sites.  NLI believes new plant construction will make it more difficult to obtain valves and replacement parts for older designs.

Sites that have an obsolete valve installed in one or a small number of locations tend to be much more willing to change to newer designs.  Plants with a large number of installations tend to go to extreme measures to obtain replacement parts for their obsolete designs.  NLI provides great options for both scenarios.

One of our clients needed an ASME III check valve, but the OEM quoted a one-year delivery time, which was unacceptable to the site.  The site had all of the internal parts plus a used sample of long lead-time item – the valve body.  NLI worked with our partner Standard Alloys to reverse engineer the valve body and manufacture a replacement.  The valve was then assembled, tested, and shipped in just nine weeks.

In other cases NLI designs complete valves to replace obsolete designs.  We design the valves to be direct replacements that function and even look nearly identical to the original.  NLI works with several vendor partners to manufacture replacement valves.

NLI also represents ValvTechnologies Inc. (VTI), which manufactures cobalt-free zero-leakage ball valves and parallel-slide gate valves for severe-duty applications.  VTI utilizes their proprietary Rocket Applied Metalic (RAM) technology to achieve extremely hard seating surfaces, which are then diamond lapped to a near perfect finish.  VTI guarantees their valves to be leakage free for four years.

 VTI’s basic ball valve design can be utilized for Electronic Relief Valves and also in throttling applications.  Smaller valves are ideal for vent and drain applications, where current valve leakage rates typically rob plants of three to four percent of efficiency.  VTI also manufactures several models of inline check valves that have far superior flow characteristics compared to more conventional swing check designs.
