Cast Steel Flanged End Ball Valve DN50 DN100 DN65 DN150 A105/F304/F316 2PC Flanged Pipeline Trunnion Mounted Ball Valve with Gear Operation

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 608, ASME B16.34, making it an ideal choice for industries such as oil & gas, water treatment, and petrochemicals.

1. Robust Cast Steel Body: Ensures long-term durability and excellent performance in high-pressure environments.
2. Soft Sealing: PTFE or RPTFE seats provide superior tightness, preventing leakage and enhancing sealing performance.
3. Versatile Applications: Ideal for liquid, gas, and low-viscosity media in industries like oil & gas, water treatment, and petrochemicals.
4. Flanged Connection: Provides a secure and leak-proof connection for stable and reliable operation.
5. Multiple Actuation Options: Supports manual, gear-operated, pneumatic, and electric actuation for varied operational needs.
6. Compliance with Standards: Designed to meet ASME, and DIN standards, ensuring international compatibility.
7. Wide Temperature Range: Operates efficiently between -29°C and 200°C, making it suitable for diverse environments.
