ABOUT M-RAO INDUSTRIES

Pioneering Flow Control Solutions With Automation

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.

  • 100% Hydro-tested Seats
  • Custom Casting Materials
  • Integrated Actuator Control
  • Tailored Face-to-Face Specs
SECTOR APPLICATIONS

Engineered for High-Consequence Environments

We customize valve designs and metallurgical specifications to resist erosion, high pressures, and chemical corrosion in critical industries.

Power Station Steam & Feedwater Isolation

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.

  • Tested for temperatures up to 550°C
  • High-integrity pressure-seal bonnet connection
  • Stellite-faced seating surfaces prevent wear
Recommended Products:
Bolted Bonnet Gate Valves Cast Steel Globe Valves

Acidic Fluid Control & Aggressive Chemicals

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.

  • ASTM A351 CF8/CF8M grade stainless steel castings
  • PTFE, RTFE, and Viton soft seals for chemical immunity
  • Fugitive emissions compliance with secondary stem seals
Recommended Products:
SS316 Ball Valves PTFE Lined Butterfly Valves

Municipal Water Networks & Sewage Treatment

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.

  • Resilient EPDM/Nitrile seats for drop-tight shut-off
  • Epoxy powder-coated internals to resist corrosion
  • Conforms to IS 14846 and BS 5163 standards
Recommended Products:
Sluice / Gate Valves Centric Wafer Butterfly Valves Dual Plate NRVs

Critical High-Flow Fire Suppression Networks

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.

  • Rising stem OS&Y Gate valves for visual status checking
  • Designed for high-speed fire hydrant supply lines
  • Complies with safety standards for high-visibility pressure control
Recommended Products:
OS&Y Gate Valves Lug Type Butterfly Valves Swing Check Valves

Hydrocarbon Processing & Refinery Pipelines

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.

  • API 6D design compliance and fire-safe API 607 standards
  • Double Block and Bleed (DBB) capability
  • Antistatic device and blowout-proof stem structure
Recommended Products:
Trunnion Mounted Ball Valves Dual Plate Wafer NRVs

QUALITY COMPLIANCE

Rigorous Testing & Metallurgical Integrity

We maintain 100% reliability by verifying every valve before it leaves the assembly lines in Ahmedabad.

Hydrostatic Pressure Testing

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.

Material Spectrometry

We verify chemical compositions of steel castings (WCB, CF8, CF8M) using spectrometer analysis to guarantee exact corrosion resistance properties.

Dimensional Conformity

Strict micrometer checks ensure all face-to-face dimensions, flange drilling, and stem tolerances match ASME B16.10/ASME B16.5 standards precisely.
