The full range of APV floating and trunnion ball valves and lubricated plug valves are also now firesafe certified to ISO 10497, 2010 and API607 5th & 6th edition as well as API6FA and are all DNV witnessed. APV is also one of the few brands in the world to have firesafe tested our API600 gate valves to API6FA and API607 6th edition and ISO 10497 - DNV witnessed. Furthermore our floating & trunnion ball, gate and globe valves are fugitive emission prototype certified to API622 2nd edition and ISO 15848-1 DNV witnessed.
Looking for 3/4" to 1 1/2", 150 to 2500 Class, small bore, trunnion mounted? APV can do it! Looking for compact/ short pattern, full port, 6" to 16", 150 - 600#, trunnion ball valves? APV can do it! Others can't!
APV floating and trunnion ball valves are solid ball, not hollow ball or “hollow core” (hollow core has a welded in cylinder in bore, a practice common amongst Chinese manufacturers). Compact quality Diamond Gear® gearboxes are used, not “China domestic” large WCB gearboxes as supplied by other brands.
We work with our sub-contractors to specifying continuous improvements to all types of valves, such as: stronger valve operators, larger stem sizes, larger surface contact seat areas, stainless steel top works components, and larger port sizes.

Quality points of difference Plug Valves
APV metal seated lubricated plug valves are specified with hard F6A/410 plug and stem in most sizes. F6A/410 stainless steel is 50% harder than 316 stainless steel and also has a much higher tensile strength. In addition to being 410 stainless, the plug, stem and lower diaphragm/plate is also nitrided (or ENP or Xylan - LoMo style coating) in most sizes. This guarantees long life for oil & gas service providing good resistance to erosion and corrosion but also makes these valves suitable for dirty and mildly abrasive service applications.
Certification Points of Difference
All steel body valves are provided with a higher level of certification than the minimum requirements of EN 10204.3.1. As well as supplying metallurgical test results on the body, we also in most cases provide it on major trim components. Furthermore, a serialised drawing can be provided for each shipment further verifying all materials.
All body and trim components are heat treated, with the required method being duly noted on the certificate.
All APV cast buttweld end valves have dye penetrant NDT (non-destructive test) performed on bevel area as standard. Other types of NDT such as UT can be performed on request.
All APV welded bonnet forged and cast valves have dye penetrant NDT performed on welds as standard
