When the Q347Y turbine mounted fixed American standard ball valve malfunctions in the pipeline and needs to be repaired, there is no need to disassemble the valve from the pipeline. Simply remove the middle flange bolt and nut, remove the valve cover and valve stem assembly from the valve body, and then remove the ball and valve seat assembly. You can repair the ball and valve seat online. This type of maintenance saves time and minimizes losses in production. High performance top mounted stainless steel ball valves can be divided into floating ball valves and fixed ball valves. Widely used in oil and natural gas pipelines, as well as in oil extraction, refining, petrochemical, chemical, chemical fiber, metallurgy, power, nuclear power, food and paper equipment.

Installation precautions for ball valves:
- Be careful during installation and construction, and avoid hitting the valve.
- Before installation, the ball valve should be inspected to verify its specifications and model, and to identify any damage, especially for the valve stem. Rotate it a few more times to see if it is skewed, as the valve stem is most likely to be knocked off during transportation. Also, remove any debris inside the valve.
- When lifting a ball valve, the rope should not be tied to the handwheel or valve stem to avoid damaging these components. It should be tied to the valve body.
- The pipeline connected to the ball valve must be cleaned thoroughly. Compressed air can be used to blow away iron oxide shavings, mud and sand, welding slag, and other debris. These debris not only easily scratch the sealing surface of the ball valve, but also block the small valve with large particles (such as welding slag), causing it to fail.
- Leave a position for the valve handle to rotate during installation.
- Ball valves cannot be used for throttling.
- Ball valves with transmission mechanisms should be installed upright.
