Quality - Assurance

We manufacture our products laying emphasis on their quality right from the procurement of the raw-materials till their dispatch. Our offered industrial valves are designed & manufactured as per the Industrial standards of ANSI, API, DIN, BS or IS. The Castings &Forgings of these valves are tested by means of chemical analysis as well as mechanical tests as per the ASTM standards. The casted and forged parts go through radiographic and ultrasonic tests respectively to ensure their flawlessness. The random samples of every batch go through various tests such as pressure testing at recommended pressure values. Our quality control department austerely checks the quality of every batch of products, to ensure that we provide our customers with only quality valves.

Hence, our valves are immensely demanded by the top-most industries in the arenas like fertilizer manufacturing, Drugs & Pharmaceuticals manufacturing, chemical manufacturing, oil fields etc. Our manufactured Valves are well-known & highly trusted for their robustness, durability, reliability, consistency and high efficiency.
