Q41F Flange Floating Ball Valve

  • model: Floating Ball Valve
  • Availability: 2023-12-13
  • category: valves
  • intro: Q41F flange floating ball valve, the ball body does not have a fixed axis of the ball valve, known as floating ball valve. Floating ball valve valve body has two seat seals, between them clamped a ball, the ball has a through-hole, the diameter of the through-hole is equal to the inner diameter of the pipeline, known as the full diameter ball valve; through-hole diameter is slightly smaller than the inner diameter of the pipeline, known as the reduction of the ball valve.

Structural features and functions of Q41F flanged floating ball valve

1. Advanced sealing performance of a variety of valve seat structure: according to the different user's different applications and requirements to design the ordinary valve seat, seat, seat, seat, seat, seat, seat, seat, seat, seat, seat, seat, seat and so on. Advanced sealing performance of a variety of valve seat structure: according to the user's different uses and requirements to design ordinary seat, elastic seat and other structures, to ensure that the valve sealing performance is reliable; long service life, reduce the operating torque of the valve.

2. The operating position of the handle is the same as the opening and closing position of the valve: the correct installation position of the handle is that the handle is parallel to the channel, and the opening of the valve can be judged according to the position of the handle, in order to prevent misuse.

3. Locking device for fully open and fully closed position of the valve: In order to prevent malfunction of the opening and closing valves, there are locking holes set in the fully open and fully closed position. The valve position can be locked to prevent other people from mistakenly moving, as well as vibration and other causes of the valve position caused by the mistaken action, to ensure the safety of the equipment.

4. Stem anti-flying structure: The lower part of the stem is designed with convex shoulder, when assembling, the stem will be loaded from the inside of the valve body, preventing the stem from flying out of the valve when the pressure inside the valve is high. At the same time can also be in the accident after the fire, the valve stem and the valve body sealing performance.

5. Anti-static function: When used in flammable media such as gasoline, natural gas, propane and other flammable media with low ignition point, the prevention of static electricity should be considered in order to avoid explosion due to the friction of static electricity between the sphere and the PTFE seat.

6. Fireproof structure: When an accidental fire occurs, the valve seat, packing.
