The double eccentric butterfly valve with ductile iron construction and EPDM seat represents advanced flow control technology engineered for demanding industrial and water applications requiring reliable performance under pressure conditions up to 16 bar. The innovative double eccentric design features two offsets that eliminate continuous disc-to-seat contact during operation, significantly reducing operating torque and mechanical wear while ensuring bubble-tight shutoff when fully closed. Manufactured from high-strength ductile iron (GGG50) with fusion-bonded epoxy coating exceeding 250 µm thickness both internally and externally, these valves withstand aggressive environments and provide exceptional corrosion resistance for long service life. Available in sizes from DN 100 to DN 1200 with PN10 and PN16 pressure ratings, they accommodate temperatures from -10°C to +80°C and support multiple actuation methods including manual gearboxes, electric, pneumatic, and hydraulic operators for flexible system integration.

These valves serve critical functions across multiple industries where reliable flow control is essential for operational efficiency and safety. In water treatment and distribution systems, they control flow in filtration processes, distribution networks, and pressure management zones with consistent performance. Power generation facilities utilize them for managing cooling water circuits and auxiliary systems where reliability directly impacts plant availability. Industrial processing plants deploy them for handling non-corrosive fluids in chemical applications, while marine engineers specify them for shipboard piping systems and offshore platforms where corrosion resistance is paramount. Their versatility extends to irrigation networks, fire protection systems, and various industrial applications where dependable flow regulation supports operational continuity and system integrity.

The business value of these valves lies in their exceptional reliability and reduced total cost of ownership through extended service life and minimal maintenance requirements. The double eccentric design minimizes mechanical wear, translating to lower operational expenses and reduced downtime for maintenance interventions. Hydraulic tested to 1.5 times PN for the body and 1.1 times PN for the seat, they deliver proven performance under pressure fluctuations and demanding operating conditions. The standardized face-to-face dimensions per IS:13095 ensure easy replacement and compatibility with existing piping systems, reducing installation time and costs. With multiple actuation options and robust construction, these valves provide dependable solutions that serious buyers trust for their critical applications, offering consistent quality and performance that protects infrastructure investments over the long term.
