Headquartered in Ahmedabad, Gujarat — India’s renowned heavy engineering hub — Allied Engineering has established itself as a premier designer, manufacturer, and exporter of severe-service industrial valves.
Unlike standard valve suppliers who outsource raw castings to disparate workshops, Allied Engineering operates an integrated production ecosystem. We maintain captive induction melting furnaces, precision shell core shooting, multi-axis CNC machine bays, and calibrated hydrostatic testing benches under our direct engineering supervision.
Our engineered portfolio encompasses Gate, Globe, Check, Ball, Butterfly, Knife Edge Gate, Pulp Valves, Strainers, and Steam Traps manufactured in accordance with strict international standards including API 600, API 6D, ASME B16.34, BS 1868, BS 1873, and MSS SP-81.
Every valve produced by Allied Engineering is backed by metallurgical discipline, dimensional accuracy, and verifiable test records.
In-house induction melting and shell core casting allow us to directly govern chemical melt ratios, degassing, and grain structure — eliminating porous castings and third-party delays.
We never rely on statistical batch sampling. 100% of finished valves undergo calibrated hydrostatic shell testing, high-pressure liquid seat shutoff, and low-pressure pneumatic seal inspection.
Every valve body is permanently heat-stamped with unique serial numbers, accompanied by EN 10204 Type 3.1 Mill Test Certificates detailing Optical Emission Spectrometer and mechanical tensile results.
Specialized foundry pouring for severe services — including NACE MR0175 sour gas (H2S), cryogenics, high-temperature steam (WC6/WC9), and highly corrosive acids (Alloy 20, Hastelloy, Monel).
To be recognized across India and worldwide as the most dependable and responsive flow-control partner for critical energy, hydrocarbon, and process applications — setting benchmarks for zero field failures.
To manufacture code-compliant, zero-leak industrial valves with uncompromising dimensional precision, full metallurgical traceability (EN 10204 3.1), and transparent delivery timelines that protect our clients' operational continuity.
Metallurgical Honesty: Absolute adherence to certified ASTM chemistry without compromise.
Total Accountability: Testing 100% of manufactured valves.
Customer Partnership: Proactive drawing approvals and open third-party inspection support.
3D SolidWorks modeling, finite element analysis, wall thickness calculation, and digital drawing approvals.
Automated shell core shooting and investment casting bays for tight-tolerance, low-roughness valve body castings.
Captive induction furnaces with argon de-gassing and on-site Optical Emission Spectrometer melt verification.
10,000 PSI calibrated hydro test benches, shot blasting, epoxy paint booths, and ISPM-15 export crating.
We welcome EPC contractors, piping consultants, and client inspection agencies (TUV, DNV, Bureau Veritas, EIL) to review our technical drawings or audit our works in Ahmedabad.
