From the heartland of Indian engineering, built on a single conviction: a valve is not a commodity — it is a commitment.
VALVAX Engineers Pvt. Ltd. was founded on a demanding premise: Indian manufacturing could compete — and win — at the highest international standards. Not by cutting corners to compete on price, but by engineering with the same rigour as the best manufacturers anywhere in the world.
Our founders had spent careers specifying, sourcing, and installing valves from global manufacturers. They understood precisely what made a great valve, what made a failing one, and why the gap between the two was invisible until the moment it mattered most.
The company was established with three commitments: materials that trace back to the ladle, processes that leave no step uninspected, and a culture where a defect reaching a customer represents a personal failure — not just a quality event.
Today, VALVAX supplies valves across oil & gas, power generation, petrochemical, water infrastructure, marine, and pharmaceutical industries across 18+ countries. Every valve we manufacture carries the weight of those original commitments.
Every VALVAX valve begins with a material selection as rigorous as any engineering decision we make. We specify only mill-certified alloys, cross-referenced against ASTM, EN, and IS standards. Heat numbers are logged in our traceability records before a single CNC programme is loaded.
Our approved supplier list is a controlled document reviewed annually. We audit casting and forging suppliers against API 20A and API 20B requirements. Where the standard is silent, our internal specification is stricter.
We do not accept material substitutions without formal engineering review. If a heat fails incoming inspection — for chemistry, tensile, impact, or hardness — the casting goes back. The programme absorbs the delay. The valve does not.
Metallurgical integrity begins in the forge. For pressure-critical components, we specify closed-die drop forging — which closes internal voids, aligns grain flow with stress lines, and produces mechanical properties that castings cannot match. For bodies and bonnets in Class 150–600 service, sand casting with 100% radiographic examination is standard.
Our investment casting capability enables complex geometries with tighter dimensional tolerances and superior surface finish — particularly valuable for trim components and tight-clearance seats. All castings undergo NDE before entering the machining programme.
We hold Class 1 (per ASME B16.34 Annex A) NDE requirements as a baseline, not a premium offering. Radiography to ASTM E94, MT or PT to ASTM E709/E165, and UT to ASTM A609 are applied based on the pressure class and service category.
Five-axis CNC turning and machining centres produce bore, thread, and flange face dimensions to ASME B16.34 and MSS SP-6 tolerances. Our CNC programme library maintains drawing-revision-controlled programmes; no operator improvisation is permitted on critical dimensions.
After each critical machining operation, dimensional inspection is performed on our Coordinate Measuring Machines (CMM). CMM data is recorded against the job card, creating a dimensional history for every valve body. Surface finishes are specified on drawings and verified by profilometry where critical.
Seat lapping is performed to optical flatness standards using lapping compounds and surface plates traceable to national standards. A valve that does not meet seat leakage criteria on the lapping bench does not proceed to final test.
Every VALVAX valve undergoes a complete API 598 test sequence. Shell hydrostatic test at 1.5× the rated working pressure, held for the full API 598 duration. Seat leakage tests — both high-pressure hydrostatic and low-pressure pneumatic — at test pressures per the applicable standard.
For fugitive emission critical applications, valves are tested to ISO 15848-1 type testing procedures and ISO 15848-2 production testing. Helium leak detection to 1×10⁻⁵ mbar·L/s is available for ultra-low emission service.
All test results are recorded in the Material Data Record (MDR), along with material test certificates, NDE reports, dimensional inspection reports, and painting/coating certificates. No valve is released without a complete documentation package.
