Manufacturing Process

STANDAR3DISATION
All products are manufactured in accordance with the guidelines of International Standard accepted all over the world such as Manufacturers Standardisation Society (MSS), American Petroleum Institute (API), American Society of Mechanical Engineers (ASME), British Standard (BS), Bureau of Indian Standard (BIS).

PROCURMENT OF RAW MATERIAL
In the manufacturing process we require Castings of different grades, Stainless steel Bars, forgings, hardware, gaskets & paints. All raw material purchase from the reputed & genuine concerned supplier.

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 motorized pump or hand pump 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 Rough 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 Hydrostatic Testing. If no leakage is found as per the relevant standard, it is sent to finishing section.

FINISING/PAINTING & PACKING
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.

Valves are packed either in wooden boxes or Gunny bags duly protected by ends enclosures and soft material to avoid any damages during transit.
