Highlight: Welded Ball Valve
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
and features rapid 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 a key component of the valve.

Product features:
1. High Efficiency and Reliability, Precise Opening and Closing:
The unique spherical structure design of welded ball
valves enables rapid response, completing opening and closing
actions in an extremely short time with stable and reliable
operation, effectively improving the operational efficiency and
control accuracy of pipeline systems.
2. Smooth Flow, Excellent Throttling: With the large-diameter
passage design of the ball, welded ball valves exhibit
minimal pressure drop during fluid transmission, allowing large and
smooth media flow. They can accurately regulate flow
rates, demonstrating excellent throttling performance to meet flow
control requirements under different working conditions.
3. Tough and Durable, Adaptable to Harsh Environments: Manufactured
from high-strength materials resistant to high
pressure and temperature, welded ball valves can operate
continuously and stably in extreme conditions such as high
temperature and pressure. They are widely used in industries with
extremely high equipment performance requirements,
such as petroleum, chemical engineering, and power, providing
reliable support for complex industrial processes.
4. Seamless Connection, Convenient and Stable: Connected to
pipelines by welding, the installation process is simple and
efficient, forming a solid and sealed integrated structure. This
effectively avoids leakage risks and ensures the safety and
tightness of the pipeline system.
5. Tight Sealing, Leak-Proof: Relying on the close cooperation
between the spherical structure and the thrust ring, when
the valve is closed, the thrust ring strongly presses the ball to
form a comprehensive and multi-layered sealing system.
This achieves excellent shut-off sealing performance, ensuring zero
leakage even under high-pressure media and
guaranteeing the safe and stable operation of the system.
