Reliant Valve Company

Your solid, dependable choice for all your needs in valve modifications, steam jacketed valves and testing.




Reliant Valve has built its reputation on providing quality, responsive personal service, and a commitment to our customer's needs. In our many years of operation, our knowledge base has provided numerous companies with the technical support they need to feel confident giving us their business . Our valve modification quality control system defines the procedures, processes, and over sight used to maintain and enhance our high level of workmanship . This system permeates every aspect of our business.

Multi-stage inspections ensure modifications meet each customers
requirements . This includes documentation of all verified first-article
materials used in the process, and then final testing based on a customer
provided specifications. We see ourselves as problem solvers, and it`s old
fashion , but we do what we say we`re going to do. Whether it`s a non-standard face-to-face dimension on a steam jacket or the repair of a valve that`s too difficult to replace, we have years of experence providing our customers the services they require.   

Our welders are ASME Boiler Code Certified and we use
the latest in both MIG and TIG welding technology. We
keep Welder Continuity Logs on all welders based on
base line WPS Certifications.

TIG welding is our primary type of welding as 75% of are work is done with that process. We have 2 Miller Syncro
Wave 350 and 1 ESAB 350 TIG machine. TIG ( Tungsten
Inert Gas) uses a non-consumable tungsten electrode to
produce the weld. The area being welded is protected by
a shieding gas like argon or an argon-helium mixture as
filler metal is added to the weld puddle. When structural integrity, deep pentration and strength are needed , this is the process used.


When thick build-up or heat effected zones are an issue we employ MIG pulse synergic welding processes. MIG or (Metal Inert Gas) uses a wire feed torch with an argon​
based gas that shields the arc. For this type of welding we use our Fornius Trans Pulse 5000 or our ESAB 450 CVCC
MIG machines.

Cryogenic extensions on ball valves require modification specs. that fall under the criteria of MSS SP- 134 & BS 6364 . Vented balls on upstream side w/arrow clearly indicating flow direction to elimenate the possibility of over pressurization from evaporation of liquid. Other cryogenic modified valve requirements deal with clearances between the valve stem and the gland extension bore to minimize heat loss due to convection. These Apollo BVs shown above were cryo modified then helium leak tested per a customers spec.​
