Highlight: Welded ball valve with strainer
Product introduction:
A welded ball valve is a commonly used pipeline connector for controlling the flow of liquids or gases in pipelines. Compared
with other valves, the welded ball valve adopts a ball structure, featuring fast opening and closing, excellent throttling
performance, etc. The valve is mainly composed of a valve body, ball, sleeve, thrust ring, handle, etc., among which the ball
is the key component of the valve. As an important pipeline control component, the welded ball valve is characterized by
simple structure, long service life, and quick opening/closing. It is widely applied in various industries and plays a vital role.

Product features:
1. The valve body adopts an integral welding structure, eliminating external leakage.
2. The valve seat is composed of a PTFE sealing ring and a spring, which has strong adaptability to pressure and
temperature changes, ensuring no leakage within the service range.
3. The stem anti-leakage structure includes a PTFE self-sealing gasket and an O-ring at the bottom, plus two O-rings and
two PTFE gaskets at the top, ensuring zero leakage.
4. The valve body material is identical to the pipeline material, avoiding stress imbalance and deformation caused by
ground extrusion from earthquakes or passing vehicles.
5. The valve body is lightweight and easy to insulate.
6. The directly buried ball valve can be installed underground without a tall valve well—only a small shallow well on the
ground is needed, greatly saving construction costs and time.
7. The length of the valve body and the height of the stem can be adjusted according to pipeline construction and design
requirements.
