Hydro-S - Válvula de mariposa con brida de PVC-U, DN50, PN10, 10 bar, palanca gris - Tipo 7500 - 7014378

Hydro-S – Butterfly Valve PVC-U Flange DN50 PN10 10 bar Grey Lever – Type 7500

Rated to 10 bar at a nominal diameter of DN50 (63 mm OD pipe), this Hydro-S type 7500 butterfly valve delivers reliable quarter-turn shut-off on PN10 flanged pipework across a service temperature range of 0°C to 40°C — well suited to pool plant rooms handling chlorinated or treated water. The PVC-U disc and body resist corrosion from pool chemicals, while the EPDM seal ensures a positive, bubble-tight closure in both flow directions.

Valve construction & materials

The disc and valve body are moulded in unplasticised PVC (PVC-U), combining chemical resistance with a light overall weight. The outer housing is reinforced glass-fibre polypropylene (PP GF) for rigidity, the spindle is steel, and the seat seal is EPDM — a combination proven in chlorinated water, mild chemical dosing lines, and general water treatment applications. The grey body with distinctive blue lever makes pool-duty service easy to identify at a glance in a busy plant room.

Conexión por brida y dimensiones

The type 7500 connects directly between standard PN10 flanges without additional adapters. Key dimensional references from the flange face: a pitch circle diameter (PCD) of 125 mm, a centre-to-face length (Ct-1) of 174 mm, and an overall installed radius (R) of 207 mm. Face-to-face width is just 45 mm (W-1), keeping the installed footprint compact. These figures align with EN 1092-1 PN10 bolt patterns at DN50, making the valve a straight swap on existing metric pipework.

Operation & plant-room suitability

A simple blue lever operates the valve with a single 90° turn, giving immediate visual confirmation of open or closed position — a practical advantage when commissioning or isolating pool filtration, heat pump, or dosing circuits. The quarter-turn action means low operating torque at this bore size, reducing fatigue during frequent seasonal cycling. Lever-operated butterfly valves of this size are widely used on commercial and large domestic pool installations to isolate pump inlets and outlets, bypass lines, and chemical injection points.
