The Ductile Iron GGG50 Ball Check Valve is a high-performance non-return valve designed to prevent backflow in pipelines while ensuring minimal pressure loss and silent operation. Constructed from premium GGG50 ductile iron (EN-GJS-500-7), this valve offers excellent strength, ductility, and corrosion resistance, making it ideal for demanding applications in water supply, wastewater treatment, sewage systems, and industrial pumping.
Key Features:
Body Material: GGG50 ductile iron with fusion-bonded epoxy coating (minimum 250 microns) for superior corrosion protection inside and out.
Ball: Rubber-coated (NBR or EPDM encapsulated steel/aluminum) for tight sealing and durability in dirty or abrasive media.
Design: Full bore for low pressure drop, self-cleaning, and non-slam closure to reduce water hammer.
Pressure Rating: PN10/PN16 (up to 16 bar).
Connection: Flanged ends compliant with DIN/EN standards (PN10/PN16).
Temperature Range: 0°C to 80°C.
Advantages: Silent and maintenance-free operation, suitable for horizontal or vertical installation, excellent for wastewater and sewage due to resistance to clogging.
This robust ball check valve ensures reliable one-way flow control, long service life, and easy maintenance with a removable cover for ball access. Perfect for municipal waterworks, pumping stations, and industrial pipelines requiring a cost-effective, high-quality check valve solution.
