Indus Industrial Group supplies heavy-duty DIN 3352 F5 (EN 558 Series 15) Long Body Resilient Seated Gate Valves engineered across nominal diameters from DN50 to DN800 in pressure classes PN10, PN16, and PN25 according to EN 1171 and EN 1074-1/2 standards. Featuring an extended face-to-face dimension, these valves are designed as direct replacements for older legacy cast iron gate valves without altering existing chamber pipework across Iraqi municipal networks. Constructed from ductile iron (EN-GJS-500-7) with 100% EPDM vulcanized wedges and stainless steel stems, they provide bi-directional drop-tight shutoff.

Municipal water network valve replacement projects, booster pump station isolation headers, water treatment plant filter manifolds, and raw river water intake stations across Baghdad, Erbil, Basra, Mosul, and Karbala.
DIN 3352 F5 Long Body Resilient Seated Gate Valves represent the essential municipal rehabilitation and replacement valve standard across Federal Iraq and the Kurdistan Region. In established municipal water distribution grids throughout Baghdad, Basra, Mosul, and Kirkuk, thousands of older flanged valves follow the traditional long pattern (DIN 3202 F5 / EN 558 Series 15). Replacing these older leaking metal-seated valves with short-pattern F4 valves creates an axial pipe gap that requires costly spool pieces or civil chamber reconfiguration. Indus F5 long-body valves drop directly into existing pipework with zero flange modification.
The valve incorporates modern resilient sealing technology: an unobstructed full-bore passage without bottom seat pockets, and a ductile iron wedge fully encapsulated in vulcanized drinking-water grade EPDM elastomer (WRAS certified). The non-rising stem is manufactured from cold-rolled stainless steel (AISI 420 / 316) with rolled trapezoidal threads, supported by low-friction polymer thrust bearings and multiple O-ring seals that are replaceable under full pipeline working pressure.
Coated inside and out with electrostatically applied blue fusion-bonded epoxy (min 250 µm, tested for zero holidays at 1.5 kV), the valve withstands aggressive subsoil moisture and high-salinity groundwater. Staged across our Erbil Heavy Plant Yard, Baghdad Central Logistics Depot, and Basra Port Hub, Indus supplies F5 gate valves with handwheels, bevel gearboxes, and full EN 10204 3.1 inspection certification.
The difference is the face-to-face length: F5 valves have a longer body (e.g., DN200 F5 is 400mm long, while F4 is 230mm long). F5 is specified whenever replacing older legacy cast iron valves so that the new valve fits exactly between existing pipe flanges without welding extra pipe spools.
Yes. For sizes DN350 to DN800, Indus supplies F5 gate valves fitted with fully enclosed, IP68 sealed bevel or spur gear reduction units that reduce operating torque, allowing single-operator manual opening and closing under full working pressure.
Every valve is delivered with an authentic EN 10204 3.1 Mill Test Certificate documenting hydrostatic shell and seat testing (1.5x and 1.1x PN), coating holiday testing, and metallographic material certification.
