Indus Industrial Group supplies heavy-duty Lug and Wafer Type Resilient Seated Butterfly Valves engineered across nominal diameters from DN50 to DN600 in pressure ratings PN10 and PN16 according to EN 593 and ISO 10631 standards. Designed with compact face-to-face dimensions for installation between standard pipe flanges, these valves feature ductile iron bodies (threaded full-lug or slim wafer) with replaceable vulcanized EPDM or NBR elastomer liners and polished 316 stainless steel or ductile iron discs. Engineered for water distribution risers, compact plant rooms, and industrial water manifolds across Iraq, they provide bi-directional drop-tight shutoff.

Commercial building booster pump skids, water treatment plant dosing galleries, HVAC chilled water manifolds, industrial cooling circuits, and fire protection isolation lines across Baghdad, Erbil, Basra, Sulaymaniyah, and Karbala.
Lug and Wafer Type Resilient Seated Butterfly Valves represent the premier compact isolation and throttling solution for plant rooms, pumping skid packages, water treatment dosing galleries, and industrial piping networks across Iraq. Where flanged valves are too bulky or heavy for confined building risers and compact skid packages in Baghdad, Erbil, and Basra, wafer and lug pattern butterfly valves sandwich directly between two companion pipe flanges using through-bolts or threaded studs, reducing installation weight by up to 60% and cutting valve face-to-face length by over 75%.
The threaded full-lug body configuration provides an essential maintenance advantage: threaded bolt holes allow the valve to be bolted directly to pipe flanges from either side, enabling dead-end service where downstream pipework can be completely removed for maintenance while the valve maintains full working pressure on the upstream side. The molded EPDM or NBR elastomer liner wraps around the body face, acting as an integrated full-face gasket that eliminates the need for separate flange gaskets.
The one-piece through-shaft or two-piece stub shaft is supported by low-friction PTFE/bronze bearings and secondary O-ring shaft seals, ensuring zero external atmospheric leakage. Staged at the Erbil Heavy Plant Yard, Baghdad Central Depot, and Basra Port Hub, Indus supplies lug and wafer butterfly valves with multi-position lockable manual levers, worm gearboxes, and pneumatic/electric actuators with full EN 10204 3.1 inspection certification.
A wafer valve is clamped between two flanges and cannot hold pressure if downstream piping is removed. A lug valve has threaded bolt lugs that allow either pipe flange to be unbolted independently, allowing maintenance crews to dismantle downstream pumps or meters while the lug valve isolates live upstream pressure.
No. The elastomeric body liner extends over the sealing faces of the valve body, serving as an integrated full-face gasket. Adding separate gaskets causes uneven torque and seal extrusion; the valve seals directly against standard raised-face or flat-face flanges.
Indus stocks lever-operated and gear-operated lug and wafer butterfly valves from DN50 to DN300 in high volume, and large sizes up to DN600 at our Erbil, Baghdad, and Basra hubs for 24-hour delivery.
