The Q41F-16P flanged ball valve features a floating ball design that ensures tight sealing under varying pressure conditions. It operates by rotating a spherical ball with a central passage 90 degrees to open or close the valve. The flanged connection provides a strong, permanent seal that can withstand high pressure and vibration, making it ideal for critical process systems. The valve can be installed in both horizontal and vertical pipelines, offering flexibility in system design.
Direct Mounting Platform: Optional standard mounting pad allows for easy integration with pneumatic and electric actuators for automated operation.
Anti-static Device: Optional anti-static feature dissipates electrostatic charges, ensuring safe handling of flammable and explosive media.
V-port Adjusting: Optional V-port ball design provides precise flow control for throttling applications, offering a wide range of flow coefficients.
Customizable Design: We offer custom engineering solutions to meet specific project requirements, including special materials, pressure ratings, and end connections.
Worm Gear Operation: For larger diameter valves, worm gear operation reduces operating torque, making manual operation easier and safer.
The flanged ball valve for oil and gas is extensively used in:
Oil and gas exploration and production
Refining and petrochemical processing
Daily chemical and fine chemical industries
Biochemical and biotechnology
