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.
