Virgin Engineers is a proactive and certified organization that is fully engaged in manufacturing, supplying and exporting Stainless Steel Instrumentation Ball Valves. Well coming to its manufacturing process we make utilized the supreme quality of raw material bought from the authorized vendors. For maintaining the product quality we thoroughly test and check the whole raw material under the supervision of quality controllers. On the other hand to attain the perfect size product we install the advanced tools and machinery in our manufacturing unit. Moreover, we have highly qualified professionals and hardworking employees that ads furnish global standard to get high end finished product. We design our products in customized shapes, size, grade, dimensions and length in order to fulfill the specific demands and requisites mention by the customers.
Stainless Steel Instrumentation Ball Valves are the type of valves that control the run of gas or liquid through means of revolving ball considering a bore. This range of ball valves features long service life and offers consistent sealing above the life span. Well talking about its grade these range of ball valves are designed from a stainless steel alloy that mainly consists of chromium and iron content. Similarly, it also includes additional content such as nickel, aluminium, copper and molybdenum content that enhances good oxidation and corrosion resistance at elevated temperatures.
These ball valves have excellent self-healing property. Due to additional content, a thin transparent layer is formed on the surface that ensures prevention from further corrosion of the surface. Therefore the high amount of chromium offers superior resistance to corrosion. In chloride environments, the valves demonstrate high resistance to pitting and crevice corrosion. Furthermore, these feature excellent tensile strength, toughness, and hardness in harsh atmospheres. These are also resistant to stress corrosion cracking and have good impact and fatigue resistance.
Basically, these alloy of valves possesses good hardenability through cold working process, therefore, these do not heat treatable. The weldability of these valves is achieved by using suitable welding methods.
Testing details - We ensure to confirm the quality of our product range on various parameters at our end. Such test is like tensile strength test, pitting resistance test, hardness test, mechanical test, chemical analysis and macro/micro test. The IGC test, ultrasonic test, radiography test, flaring test, hydrostatic test and flattening test are also performed by us.
Test certificates - To ensure that the product we are offering is designed from high-quality material, therefore we offer approved MTC to our patrons. These certificates are like raw material test certificates, 100% radiography test reports and third-party inspection reports.
Documentation - At the time of transportation of the product, essential reliable documentation is attested along with the product. This documentation is like a quality assurance plan, heat treatment charts, NABL approved lab test reports, fumigation certificates, guarantee letter, and commercial invoice.
Packing & marking -By using optimum quality of packaging material we appropriately packed the products in wooden boxes, wooden cases, wooden pallets, and wooden cartons and in wooden cases that provides great prevention and safety from any type of rust and harm during transit.
