PREETAM DI Double Eccentric Disc Butterfly Valves represent advanced engineering in flow control technology, designed specifically for demanding industrial and municipal applications. The double eccentric disc design significantly reduces operating torque while ensuring bubble-tight shut-off, making these valves exceptionally efficient and reliable. Constructed from high-grade ductile iron (GGG50) with fusion-bonded epoxy coating exceeding 250 µm thickness, these valves offer superior corrosion resistance both internally and externally. The EPDM-lined disc with minimum 2mm thickness and stainless steel retainer system ensures long-term sealing integrity, while the standardized face-to-face dimensions (IS:13095) guarantee easy installation and replacement compatibility. Available in sizes from DN 100 to DN 1200 with PN10/PN16 flange ratings, these valves handle pressure requirements up to 16 bar with comprehensive hydraulic testing validation.

These butterfly valves serve critical roles across multiple industries where precise flow control and reliable isolation are paramount. In water and wastewater treatment facilities, they manage flow in distribution networks, pumping stations, and treatment processes. Power generation plants utilize them in cooling water circuits and auxiliary systems, while industrial manufacturers deploy them in process lines and utility services. The chemical industry benefits from their compatibility with non-corrosive fluids, and fire protection systems rely on their immediate shut-off capabilities. Marine applications find them ideal for shipboard water systems, and agricultural sectors use them extensively in irrigation networks. Their versatility extends to HVAC systems, district heating networks, and stormwater management infrastructure, demonstrating broad applicability across essential services.

The business value of PREETAM Double Eccentric Butterfly Valves extends beyond initial purchase to long-term operational reliability and cost efficiency. Their low-maintenance design reduces downtime and service requirements, while the robust construction minimizes replacement frequency, delivering exceptional return on investment. The availability of multiple actuation options including manual gearboxes, electric, pneumatic, and hydraulic operators allows customization to specific operational needs. Manufacturing compliance with international standards ensures consistent quality and performance, backed by rigorous testing protocols including body testing at 1.5 times PN and seat testing at 1.1 times PN. This commitment to quality assurance provides peace of mind for critical infrastructure projects where valve failure is not an option.
