Combine this experience with state of the art equipment such as ultrasonic tests, x-rays, laser measurement equipment, and applications like computerized Finite Element Analysis (FEA) and it is no wonder why supertech has some of the best performance products on the market.\u003c\/p\u003e \u003cp\u003eWhile this is more than most manufacturers we don’t stop there. We also do extensive testing working very closely with many of today's top engine builders in order to continuously improve our products. All of this is meant to insure Supertech's industry leading reputation for high flow rates, durability and uncompromising quality.\u003c\/p\u003e \u003ch3\u003eENGINE VALVE MANUFACTURING\u003c\/h3\u003e \u003cp\u003eProduction of our racing valves begins with a one piece forging, where the head of the valve is forged under a slow two step process to keep a good material grain flow. The forging is then CNC machined in several steps to ensure the precision of the final dimensions. We then do another heat treatment for stress relieving followed by a nitride hardening treatment (or coating process depending on the application). Lastly, we do one more grinding, followed by our patented Superfinishing of the surface to ensure that each valve is free of any imperfections and the dimensions are precise.\u003c\/p\u003e \u003ch3\u003eONE PIECE VALVE\u003c\/h3\u003e \u003cp\u003eOur valves are not finished from generic blanks rather they are specifically designed for each and every application. We work relentlessly, testing and researching every aspect trying to improve the air flow of our designs.\u003c\/p\u003e \u003ch3\u003eDURABILITY\u003c\/h3\u003e \u003cp\u003eWith every valve design we strive to maximize durability through higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc. \u003c\/p\u003e \u003ch3\u003eSTRICT TOLERANCES\u003c\/h3\u003e \u003cp\u003eIt’s unlikely you will find any of our competitor’s valves with stricter dimensional tolerances than our Supertech valves. Combine that with finished seats with equally strict run out tolerances and you won’t find a better sealing, better performing and easier to install solution anywhere!\u003c\/p\u003e \u003ch3\u003eSUPERFINISH\u003c\/h3\u003e \u003cp\u003eIn 2006 we introduced our stem Superfinishing as a standard addition to all of our valves and provided it at no additional cost. When our Superfinish is combined with our Black Nitrided valve it reduces the surface roughness to 1\/3 of our chrome coated valve. The end result… unsurpassed performance and durability.\u003c\/p\u003e \u003ch3\u003eHIGHER FLOW RATES\u003c\/h3\u003e \u003cp\u003eOptimum high flow rates are achieved by ensuring that our valves are manufactured with the best angles for each application. We consider back cut, under cut and valve head angles for each application to produce the optimum high flow rates for each application.\u003c\/p\u003e","brand":"Supertech","offers":[{"title":"Exhaust Valve \/ Inconel \/ 114.9mm x 5.95mm Sodium Filled x 28.00mm","offer_id":62759847461194,"sku":"BMEVI-1054S-HS","price":76.76,"currency_code":"GBP","in_stock":true},{"title":"Intake Valve \/ Black Nitrided \/ 106.7mm x 4.96mm x 31.40mm","offer_id":62759847493962,"sku":"BMIVN-1054S","price":36.05,"currency_code":"GBP","in_stock":true},{"title":"Intake Valve \/ Black Nitrided \/ 111.75mm x 4.97mm x 35.40mm","offer_id":62759847526730,"sku":"BMIVN-1065","price":40.15,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1059\/6116\/1034\/files\/supertech-intake-and-exhaust-valves-bmw-n54b30a-valve-inconel-114-9mm-x-5-95mm-sodium-filled-28-00mm-cams-valvetrain-691_a0c60b04-8934-44bb-b8e7-3c109bc9ee23.webp?v=1784424871"},{"product_id":"supertech-5-0mm-valve-lock-7-degrees-2-per-valve-bmw-n54b30a","title":"Supertech 5.0mm Valve Lock - 7 degrees (2 per valve) BMW N54B30A","description":"\u003cp\u003eSupertech valve keepers (also known as collets) are precision machined using high quality material to give a finished product worthy of Supertech's established reputation.\u003c\/p\u003e","brand":"Supertech","offers":[{"title":"Default Title","offer_id":62759847559498,"sku":"KPR-5.0\/7S","price":4.2,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1059\/6116\/1034\/files\/supertech-5-0mm-valve-lock-7-degrees-2-per-bmw-n54b30a-cams-valvetrain-887_634c27d7-7b5a-424b-99ad-6289681841fd.webp?v=1784424871"},{"product_id":"supertech-6mm-single-valve-lock-conversion-7-degrees-bmw-n54b30a","title":"Supertech 6mm Single Valve Lock conversion - 7 Degrees BMW N54B30A","description":"\u003cp\u003eSupertech valve keepers (also known as collets) are precision machined using high quality material to give a finished product worthy of Supertech's established reputation.\u003c\/p\u003e","brand":"Supertech","offers":[{"title":"Default Title","offer_id":62759847592266,"sku":"KPR-6S\/7-5","price":2.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1059\/6116\/1034\/files\/supertech-6mm-single-valve-lock-conversion-7-degrees-bmw-n54b30a-cams-valvetrain-660_3135010c-d39f-4366-b7eb-b56b74823741.webp?v=1784424872"},{"product_id":"supertech-conical-valve-spring-and-retainer-kit-75lbs-at-36-5mm-bmw-n54b30a","title":"Supertech Conical Valve Spring and Retainer Kit 75lbs at 36.5mm BMW N54B30A","description":"\u003cp\u003eAll Supertech valve springs are made with premium Superclean Chrome Silicon Vanadium Steel alloy for higher performance durability at high rpms.
