Highlight: Anti theft 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, it adopts a ball structure and features rapid opening and closing, good throttling performance, etc. The
valve is mainly composed of a valve body, ball, sleeve, thrust ring, and handle, among which the ball is a key component of
the valve.

Product features:
1. Fully Welded Body, Leak-Proof Design:Utilizes an integrated full-welding process to eliminate leakage risks at the
source. The compact and精巧 design simplifies installation, ensuring efficiency and reliability.
2. Low-Torque Operation, Energy-Efficient & Smooth:Equipped with PTFE self-lubricating metal bushings to minimize
friction resistance, enabling effortless valve operation even under low-torque conditions.
3. Double Block & Bleed (DBB) Function, Safe & Efficient: When the valve is closed and both sides of the ball are
pressurized, the drain valve allows rapid discharge of internal media (gas or liquid), ensuring dual isolation and safe
system maintenance.
4. Dual Piston Effect Seat, Double Protection: The innovative seat design employs a dual piston effect to achieve
bidirectional sealing under pressure. If the upstream seat is damaged and leaks, downstream pressure automatically
forces the seat into tight contact with the ball, activating downstream sealing to guarantee zero leakage.
