Product Description

Key Features & Benefits

· Strong Structural Design: The ductile iron body provides excellent mechanical strength and impact resistance, ensuring safe operation under PN10 and PN16 pressure conditions.

· Reliable Sealing Performance: Equipped with resilient rubber seats such as EPDM or NBR, the valve ensures tight shut-off and stable sealing over long service periods.

· Lug-Type Connection: Threaded lugs enable easy installation and removal without disturbing the downstream pipeline, improving operational flexibility.

· Smooth Operation: Optimized disc geometry minimizes flow resistance and reduces operating torque, allowing smooth manual or actuated operation.

· Wide Application Range: Suitable for both on/off service and flow regulation in municipal and industrial systems.
