The Q41F type ball valve performs a 90-degree rotation operation. Its uniqueness lies in the design of the valve core as a sphere with a circular passage inside. This type of ball valve is primarily used in pipeline systems to achieve the cutting, distribution, and adjustment of fluid flow. By rotating only 90 degrees and applying minimal torque, the ball valve can achieve a tight shut-off effect.
● Fire Safe Design: The valve with fire construction can maintain the integrity of its structure and function in case of fire.
● Anti-Static Device: These devices help reduce the possibility of ignition and maintain a safe operating environment by ensuring the safe release of static charges.
● Low Emission Control:Valves designed to minimize the release of harmful gases or vapors into the atmosphere, aiming to minimize emissions.

Q1: What makes the side-entry structure beneficial?
A: It allows for easy internal maintenance without removing the valve from the line, reducing downtime and service complexity.
Q2: Is this valve suitable for automation?
A: Yes, the valve supports manual, pneumatic, and electric actuation for flexible control options.
We use top-grade stainless steel and alloy steel as the core materials, aiming to ensure the robustness and corrosion resistance of the valves, thereby extending their service life. By integrating advanced precision casting and mechanical processing technologies, each valve undergoes rigorous quality inspection to guarantee its sealing performance and smooth operation. We offer a variety of specifications, pressure, and temperature ratings to meet the specific requirements of various industrial applications.
