Q11F three-piece high-platform ball valve
Other Products
I. Introduction:
The Q11F three-piece high-platform ball valve features a simple structure, quick opening and closing, small size, light weight, easy operation and maintenance, and a wide range of applications. The special advantage of high-platform ball valves over other ball valves is that their sealing surfaces are not easily worn, with no friction during opening and closing, enabling full regulation and blocking of the medium. They are widely used in working environments with high requirements for flow interception, such as petroleum and chemical industries. The three-piece high-platform ball valve should be classified as a stop valve in the fields of marine engineering and ships. It is defined in the standard GB/T21465-2008 "Valve Terminology" as: a valve whose opening and closing part (sphere) is driven by a valve stem and rotates around the axis of the square-work ball valve. It can also be used for fluid regulation and control. Among them, the hard-sealed V-shaped ball valve has strong shear force between its V-shaped ball core and the metal valve seat with surfaced hard alloy, making it especially suitable for media containing fibers, tiny solid particles, etc.
II. Features:
（1）Small fluid resistance; full-bore ball valves have almost no flow resistance.
（2）Simple structure, small size, and light weight.
（3）Tight and reliable. It has two sealing surfaces, and currently various plastics are widely used as sealing surface materials for ball valves, ensuring good sealing performance and achieving complete sealing. It is also widely used in vacuum systems.
（4）Convenient operation and quick opening/closing; only a 90° rotation is required from fully open to fully closed, facilitating remote control.
（5）Easy maintenance; the ball valve has a simple structure, and the sealing rings are generally movable, making disassembly and replacement relatively convenient.
（6）When fully open or fully closed, the sealing surfaces of the sphere and valve seat are isolated from the medium, so the medium will not cause erosion to the valve's sealing surfaces when passing through.
（7）Wide application range; the nominal diameter ranges from several millimeters to several meters, and it can be applied from high vacuum to high pressure.
（8）Due to the wiping action during the opening and closing process of the ball valve, it can be used for media with suspended solid particles.
III. Technical Parameters:
①Connection form: Internal thread
②Nominal diameter: 1/2”∼4”
③Applicable media: Water, oil, steam, carbonic acid, nitric acid
④Pressure range: 1000WOG
⑤Opening/closing force (N): 400∼500
⑥Applicable temperature: -40~200 (°C)
⑦Body material: Stainless steel 304/316
⑧Design and production standards: Designed and produced in accordance with standards such as JB, ISO, API, GB, BS, etc. Its safety and quality have been strictly tested and it is supplied to domestic and foreign markets.
IV. Installation Instructions:
（1）Remove the protective covers from both sides of the flange end, and flush and clean the valve while it is fully open.
（2）Before installation, conduct a full machine test according to the specified signal (electric or pneumatic) (to prevent vibration during transportation from affecting performance). Only after passing the test can it be put into online installation (wiring shall follow the wiring diagram of the electric actuator).
（3）Before preparing to connect to the pipeline, flush and remove residual impurities in the pipeline (these substances may damage the valve seat and sphere).
（4）During installation, do not use the actuator part of the valve as a lifting point to avoid damaging the actuator and accessories.
（5）This type of valve shall be installed in the horizontal or vertical direction of the pipeline.
（6）The pipeline near the installation point shall not sag or bear external force; pipeline supports or supports can be used to eliminate pipeline deviation.
（7）After connecting to the pipeline, tighten the flange connecting bolts crosswise with the specified torque.
