1.Ball valve is the control part of the pipeline system that can quickly truncate and connect the flow of the javascript:void(0);medium. In the process of use, the valve must be fully open or fully closed and cannot be used as the regulating flow
2.Ball valve has internal and external thread, card sleeve, hot melt connection, valve body and bonnet adopt thermostatic hot forging and tempering process, which greatly improves the mechanical performance and safety factor of valve.Valve pressure test was strictly performed according to GB/t13927-1992 < general valve pressure test > standard, 100% of the test was qualified before delivery.
3.Installation of valve must be carried out by professional personnel with relevant qualification. The deviation of the two ends of the pipe shall not be too large, otherwise excessive pipe installation stress will be produced, resulting in valve damage.When installing the screw, it should wrench the hexagon or octagonal parts of the same side of the thread, not the hexagon or octagonal parts on the other end of the valve, avoiding the deformation of the valve.
4.Valve pipe thread accuracy and effective length strictly enforce ISO228 standard, when installing a tightening must choose corresponding torque wrench or pliers, screwing length of screw thread can effectively, do not lead to excessive pressure in the end, cause valve, sealing surface breakage and leakage.
5.To ensure the normal use of the valve, install the filter at the inlet of the line whenever possible.In order to avoid pipeline pressure or temperature fluctuation to reduce the service life of the valve, corresponding preventive measures should be designed.
6.The ball valve handle is designed according to the use of the valve and the corresponding torque. Do not replace the lever arm, so that the operating torque is too large to damage the valve.In the process of use, the closing speed of the valve should not be too large, otherwise the water hammer effect will be doubled
7.Valve stem seal packing is polytetrafluoroethylene, such as the turbine-tightening cap to compensate the filling when the corrosion leak, replace the packing to remove the media pressure.

30mm Dovetail Scope Rings are a specific type of dovetail mounting system designed to accommodate rifle scopes with a 30mm main tube diameter. These rings feature a dovetail design that slides into a corresponding dovetail-shaped groove on the firearm's receiver or rail system. The 30mm measurement refers to the internal diameter of the scope rings, which is the size of the scope tube they are designed to hold securely.
As with other dovetail scope rings, 30mm Dovetail Scope Rings offer certain advantages, such as:
-
Low profile: The dovetail design provides a streamlined and low-profile setup, which can be aesthetically pleasing and reduce the overall bulk of the firearm.
-
Secure fit: The interlocking design of the dovetail system ensures a stable and secure connection between the scope and the firearm, minimizing the chance of the scope shifting during use.
-
Easy installation and removal: Dovetail scope rings can be easily installed or removed, making it simple to adjust, maintain, or swap scopes between firearms.
However, it is essential to note that 30mm Dovetail Scope Rings are designed specifically for scopes with a 30mm main tube diameter, and they may not be compatible with scopes of other sizes. Additionally, dovetail mounting systems may not be as versatile as other systems like Picatinny or Weaver rails, which can offer more mounting options and are compatible with a wider range of accessories.
