The Q41F Cast Steel Soft Sealing Flanged Ball Valve is designed for industrial applications requiring high performance, reliability, and durability. Made from high-quality cast steel (WCB), it is suitable for handling liquids, gases, and low-viscosity media under high-pressure conditions.
The soft sealing design, using PTFE or RPTFE seats, ensures exceptional leak-proof performance and a longer lifespan. Its flanged connection provides easy installation and maintenance, while the availability of multiple actuation methods allows customization based on operational requirements.
This ball valve meets stringent international standards such as API 608, ASME B16.34, and API 598, making it an ideal choice for industries such as oil & gas, water treatment, and petrochemicals.
