The Ductile Iron GGG50 Rubber Seated Swing Check Valve is a reliable and durable non-return valve designed to prevent backflow in pipelines. Constructed from high-quality GGG50 ductile iron (EN-GJS-500-7), it offers excellent tensile strength (minimum 500 MPa), superior toughness, and corrosion resistance compared to traditional cast iron.
The resilient rubber seated disc (typically EPDM or NBR) ensures a tight seal, drip-free shut-off, and low pressure drop, making it ideal for water supply, wastewater treatment, sewage systems, and general industrial applications.
Key Features:
Body and disc material: Ductile iron GGG50 with epoxy coating (minimum 250-300 microns) for enhanced durability and longevity.
Swing disc design allows full flow with minimal resistance.
Flanged ends compliant with standards such as PN10/PN16, ANSI Class 125/150.
Bolted cover for easy maintenance; optional lever, counterweight, or damper for controlled closing.
Suitable for horizontal or vertical installation; operating temperature up to 120°C.
Compliant with standards: BS 5153, EN 12334, AWWA C508, API 6D.
This swing check valve provides low maintenance, high performance, and cost-effective backflow prevention in demanding environments.
