Founded under the vision of proprietor Rajesh Kumar Yadav, M-RAO Industries has established itself as an engineering benchmark in manufacturing industrial valves and strainers.
Operating from our modern corporate sales office in Darya Ganj, Delhi and our state-of-the-art manufacturing factory in Narol, Ahmedabad, we build products that strictly comply with global industry certifications (API, ASME, BS, DIN, IS). Our engineering focus lies in mechanical durability and integrating actuator units to allow remote telemetry and automatic flow shut-offs.
We customize valve designs and metallurgical specifications to resist erosion, high pressures, and chemical corrosion in critical industries.
Superheated steam and high-pressure boiler lines require absolute sealing and thermal relief. Our high-pressure gate and globe valves are forged to withstand intense thermal expansion and prevent pipeline shocks.
Corrosive media in chemical pipelines require high-alloy cast valve bodies like ASTM CF8M (SS316) and PTFE lining. Our ball and butterfly valves prevent external fugitive emissions and packing leakage.
High-volume municipal lines require robust design, lower torque operation, and low flow restriction. Our large diameter butterfly valves and resilient seated gate valves are designed to minimize head loss and shut off reliably.
In fire systems, valves must remain open or closed for months and operate immediately in emergencies. Our gate, butterfly, and check valves offer visual position indicators and low operating torque.
Refineries demand fire-safe certifications and fugitive emission-compliant valves. Our trunnion-mounted ball valves and heavy-duty check valves handle crude oil, LPG, and high-pressure gas distribution safely.
All product categories are designed for clean display and structured specifications, conforming to industry sizes and standards.
Two-piece split-body flanged ball valve providing full bore flow with low pressure drop. Includes slotted PTFE seats, anti-static device, and fire-safe design.
Three-piece bolted construction flanged ball valve enabling inline servicing without removing end connections. Features blow-out proof stem and bubble-tight shutoff.
Resilient seated centric disc butterfly valve with electric rotary actuator for automated flow control. Features ISO 5211 direct mount interface.
Full bore flanged ball valve integrated with an electric actuator for automated on/off service. Equipped with ISO 5211 pad and fire-safe seal.
Compact screwed end ball valve paired with an electric actuator for pipeline automation. Built with slotted PTFE seats, blow-out proof stem, and ISO 5211 mount.
High-performance flanged ball valve with pneumatic rack-and-pinion actuator for rapid emergency shutoff and cycling. Features ISO 5211 direct mounting.
Self-operating swing check valve engineered to prevent backflow in liquid and gas pipelines. Features full-flow body, bolted cover, and renewable seat rings.
Forged steel gate valve with outside screw & yoke (OS&Y), bolted bonnet, and rising stem. Designed for high-pressure industrial isolation.

We maintain 100% reliability by verifying every valve before it leaves the assembly lines in Ahmedabad.
Every valve body is shell-tested at 1.5 times the pressure rating. Seats are hydro-tested and pneumatically tested to check for zero-leak bubble compliance.
We verify chemical compositions of steel castings (WCB, CF8, CF8M) using spectrometer analysis to guarantee exact corrosion resistance properties.
Strict micrometer checks ensure all face-to-face dimensions, flange drilling, and stem tolerances match ASME B16.10/ASME B16.5 standards precisely.
