In a yet another milestone for R&D Multiples, we are proud to announce that we have successfully delivered 19 nos of 3000mm/120’’ Butterfly valves with a design pressure rating of 1.6 MPa in a record time of 5 months post manufacturing clearance from the client. These valves will subsequently be installed in the prestigious Narmada Malwa Gambhir river link project in the state of Madhya Pradesh, India. This project intends to provide irrigation facilities in 158 villages covering 50,000 hectares of area in Indore and Ujjain districts.

Basic Design

• Design Standard: Face to Face dimension as per AWWA C516
• Flange Drilling Standard: AWWA C207 Class D (Flat Face)
• Design Pressure: 1.6 MPa
• Mode of Operation: Manually operated through R&D Multiples make Quarter-turn worm gearbox with hand-wheel

Testing

• Seat test pressure: 17.6 kg/cm2
• Body test pressure: 24 kg/cm2
• Disc strength test: 24 kg/cm2

The activities conducted during these 5 months include detailed engineering, FEA analysis (for optimization of the design), pattern making and then procurement of castings from a reputed, wellequipped foundry. Our team then worked round the clock to make sure that we meet the required delivery deadline. This is the largest diameter valve that we have manufactured till date and beats our previous best of 2800mm/112” hydraulically operated butterfly valve that we manufactured in 2016 for NTPC’s Kudgi thermal power station. In addition to these 19 valves, we also delivered 122 nos of valves (butterfly and gate valves combined) for the same project of sizes ranging from 200mm to 2500mm in the same timeframe. This further demonstrates our execution capabilities and is a clear source of advantage to all our customers.

We are one of the leading manufacturers of valves used in waterworks applications all over India. Founded over 3 decades ago, we have developed a wide product range over the years. We make valves up-to 3.5 meters size & 40 bar pressure ratings. A wide variety of operators & actuators as drives & many accessories are also offered to make the valve versatile & user friendly. The materials offered to suit customer specifications range from Cast Iron, Carbon Steel, Stainless steel & other corrosion resistant/ high strength alloys.
