At DN200 (225 mm OD) with a PN10 flange rating, this is one of the largest lever-operated PVC-U butterfly valves in the Hydro-S Type 7500 range \u2014 suited to high-volume water management in commercial pools, water treatment plant rooms, and large-diameter pipework systems. The PVC-U disc and body deliver genuine corrosion resistance without the weight penalty of metal alternatives, while the EPDM seat seal ensures a reliable bi-directional shut-off up to 10 bar.<\/p>\n
The valve body and disc are manufactured entirely from PVC-U, making the wetted parts fully resistant to chlorinated pool water, salt water, and common treatment chemicals. The glass-fibre reinforced polypropylene (PP GF) housing provides structural rigidity around the PVC-U internals, and the EPDM elastomer seal offers dependable compression sealing across the rated temperature window of 0 \u00b0C to 40 \u00b0C \u2014 covering all practical pool and water-plant operating conditions.<\/p>\n
The PN10 flange pattern conforms to EN 1092-1, with a pitch circle diameter (PCD) of 295 mm and an overall radius (R) of 335 mm, allowing straightforward bolt-up to standard PN10 counterpart flanges. The face-to-face dimension (Ct-1) is 256 mm, with face widths of 75 mm (W-1) and 115 mm (W-2). At DN200 these dimensions are best verified against your pipework drawing before ordering, as mismatched drilling patterns are a common installation error at this pipe size.<\/p>\n
A blue lever provides simple quarter-turn on\/off actuation \u2014 open to closed in 90\u00b0. The steel spindle is dimensioned for the torque demands of a DN200 disc and, at this valve size, lever operation remains practical for manual isolation duties. For frequent cycling or actuated control applications, the lever can typically be replaced with a gearbox or actuator mounting head \u2014 consult the Hydro-S Type 7500 accessory range for compatible drive assemblies.<\/p>","protected":false},"excerpt":{"rendered":"
