QUALITY CONTROL: All raw materials are checked by our Quality Assurance Department prior to manufacturing process. For an example, when we received the castings, it is checked visually and dimensionally for machining tolerance. We also check the foundry chemical Test Certificate and physical test certificate, compared to suitable international standard and passed to machining shop for the further process, if it is rejected it is send back to the supplier.
MACHINING: The raw material issued to the machine shop for the machining, is machined strictly as per the relevant drawings.
INPROCESS TESTING: If it is found OK dimensionally the valve body and bonnet are sent for the hydro testing. All internal parts such as seat, disc, stem are measured by the Vernier Caliper or micrometer, if it is found O K than pass to assembly section for the further assembly. All the valve body and bonnet are tested on the hydraoulic testing pumps as per the relevant standard. The theory being, when the body or the bonnet is under pressure there should not be any leakage or drops of the testing fluid from any portion of the castings. If any leakage observed, it is rejected and sent back to the foundries.
ASSEMBLY: The body and bonnet, which are Hydrostatically O K, are sent to assembly section, duly handled with care to avoid the scratches on the machined surfaces. In the assembly section body and bonnet are drilled on drill machine with the help of jigs & fixtures for uniformity and interchangeability.
LAPPING: In metal to metal seated valves, seat & disc/plug are lapped by Extra courses Lapping Paste to smoothen the seating surface and than lapped with very fine grade lapping paste for the proper sealing of disc & seat surface, to ensure zero leakage.
TESTING: After assembly of new complete valve is sent for Hydroslic Testing pumps & Air Testing. If no leakage is found as per the relevant standard, it is sent to finishing section.
FINISING/PAINTING: The valve body and bonnet is debarred and finished by flexible shaft grinders for better appearance. One coat of corrosion resistance primer (red oxide) is sprayed, and colored as per the codes, twice for superior surface look.
INFRASTRUCTURE: We hold a state-of-the-art infrastructure. We are completely attired up with all modern and imported machinery and tools that are efficiently handled by a team of skilled labor. These are the reason behind our ability to make available an entirely inventive range of products.
