Rated to a full 10 bar at PN10 flange standard and sized for DN100 (110 mm) pipework, this lever-operated PVC-U butterfly valve from Hydro-S delivers reliable quarter-turn isolation in commercial pool plant rooms, water treatment circuits, and any chlorinated-water system where corrosion resistance is paramount. The compact face-to-face depth of just 56 mm (W-1) keeps installation tight, while the 180 mm PCD bolt pattern aligns directly with standard PN10 counterpart flanges.<\/p>\n
The valve body and disc are moulded from PVC-U \u2014 a material well proven in swimming pool pipework for its resistance to chlorinated media and chemical cleaning agents. The housing is reinforced with glass-filled polypropylene (PP GF) for added structural rigidity, and the seat seal is EPDM, which provides a bubble-tight shutoff across the full 0 \u00b0C to 40 \u00b0C operating temperature range. The steel spindle transmits lever torque efficiently without the weight penalty of a cast-iron alternative.<\/p>\n
The double-flange configuration bolts directly between PN10 mating flanges \u2014 no solvent welding, no union joints. With a pitch circle diameter of 180 mm, an overall radius of 207 mm, and a face-to-face length of 115 mm (W-2), the Type 7500 fits the dimensional envelope expected of DN100 PN10 valves throughout Europe. The blue lever provides clear open\/closed indication and is operable without tools, making routine isolation straightforward for pool technicians and installers alike.<\/p>\n
A DN100 butterfly valve is suited to high-flow commercial pool plant rooms \u2014 typically serving main circulation headers, backwash lines on large sand or DE filters, or bypass circuits on commercial heat pumps where pipework of 110 mm OD is standard. PVC-U butterfly valves of this type are broadly used in swimming pool technology and pool construction for their suitability with chlorine-containing media, offering a cost-effective alternative to stainless steel or cast-iron isolating valves in above-ground plant-room installations.<\/p>","protected":false},"excerpt":{"rendered":"
