Highlight: Underground double released welded ball valve
Product introduction:
The fully welded directly buried ball valve breaks through
traditional design, adopting an integrated full-welding structure
that
allows stable operation after being directly buried underground.
There is no need to construct an underground valve control
room; operators can complete precise transmission operations
through a T-handle on the ground, which greatly enhances
operational convenience and safety. This completely eliminates the
safety risks of personnel entering underground for
operations and effectively avoids potential safety hazards of
traditional underground control rooms, such as limited space,
poor ventilation, moisture-induced leakage, etc. In terms of
product adaptability, the fully welded directly buried ball valve
demonstrates strong customization advantages. It can be
tailor-designed with different valve heights according to the
burial
depth requirements of users' gas pipelines, ensuring perfect fit
with the engineering environment. Meanwhile, aiming at
customers' diversified pipeline connection needs, it provides
various valve end connection methods. Whether flange
connection, welded connection, or other special interfaces, all can
be customized as required, offering flexible and reliable
solutions for various gas transportation projects.

Product features:
1. High reliability: Welded ball valves adopt a ball structure,
featuring fast opening and closing with reliable operation.
2. Excellent throttling performance: The ball of welded ball valves
has a large through-bore diameter, resulting in low
pressure drop, large flow rate, and superior throttling
performance.
3. High pressure and temperature resistance: Welded ball valves can withstand harsh working conditions such as high
pressure and high temperature, being widely used in industries like
petroleum, chemical, and power.
4. Easy installation: Welded ball valves are connected to pipelines
by welding, featuring simple installation and low risk of
leakage. 5. Good shut-off sealing performance: Welded ball valves
adopt a ball structure, with the thrust ring pressing the
ball to form a reliable seal.
