i. Scope of use

ball Valve is mainly used to cut off, distribute and change the medium flow direction on the pipeline. In order to prolong the service life of ball valve, it should be fully open and fully closed.

II. Main technical parameters of the product:

1. Select high-quality copper and adopt hot forging process

2. The working medium of ball valve is water, oil, gas, etc.

3. Working temperature-20 ℃ ≤ t ≤ 150 ℃.

4. Nominal pressures are 2.5MPa, 2.0MPa and 1.6MPa respectively.

III. Installation Guide

1. When installing the ball valve connected by pipe thread, the pipe should be perpendicular to the end face of the valve body, and the hexagonal or octagonal parts of the same side end of the thread should be clamped, the hexagon or octagonal or other parts of the other end should not be wrench to avoid deformation of the valve body or affecting opening.

2. When connecting the ball valve with internal thread, the length of the external thread of the pipe end must be controlled, so as to avoid that the thread of the pipe end is too long, and the end face of the internal thread of the ball valve is pressed when it is rotated, which causes the deformation of the valve body and affects the sealing performance.

3. When the ball valve connected by pipe thread is connected with the thread of the pipe end, the internal thread can be conical pipe thread or cylindrical pipe thread, but the external thread must be conical pipe thread, otherwise, the connection will not be tight and leakage will occur.

4. The upper indexing circle of flanged ball valve should be consistent with the size of the indexing circle of the pipe flange. The center of the pipe at both ends should be perpendicular to the flange surface of flanged ball valve, otherwise the valve body will be twisted and deformed.

5. When installing the ball valve connected by pipe thread, the sealing material should be clean and clean.

6. Pay attention to no obstacles in the opening and closing range of the ball valve handle during installation, such as walls, pipes, connecting nuts, etc.

7. When the ball valve handle is parallel to the valve body, it is open, and when it is vertical, it is closed.

8. The medium should not contain particles, corrosive gases or liquids.

9. Pp-R tube Ball Valve installation:

①. Remove the connecting nut, PP-R pipe flange and O-ring on the valve body respectively.

②. Put the removed connecting nut into the wheel cover according to the original pp-R tube.

③. Combine the PP-R pipe flange with the PP-R pipe hot-melt machine after fusion. After cooling, insert the O-ring into the PP-R pipe flange step, and finally tighten the connecting nut with the valve body.
