PE Double Bleed Ball Valve
The PE Double Bleed Ball Valve is a high-safety polyethylene valve specifically designed for gas distribution pipeline systems. Manufactured from premium PE100 high-density polyethylene, this advanced valve integrates pipeline shut-off, dual-side pressure release, venting, and pressure testing functions into one compact unit.
Featuring a full-port flow structure and a 90-degree manual operation design, the valve supports both butt fusion and electrofusion welding with PE pipelines, creating a fully integrated and leak-free connection. The dual independent bleed ports allow separate venting of upstream and downstream pipeline sections, making the valve ideal for gas pipeline maintenance, emergency repair, sectional isolation, pressure testing, and purge operations.
Widely used in municipal gas transmission networks, residential gas distribution systems, underground PE pipelines, and industrial gas projects, the PE Double Bleed Ball Valve delivers maximum operational safety, long-term durability, and reliable sealing performance in demanding field conditions.

Key Features & Benefits
Dual Independent Bleed System for Maximum Safety
The valve is equipped with upstream and downstream bleed outlets, allowing operators to independently release residual gas pressure from either side of the pipeline. This significantly improves maintenance safety and minimizes risks during repair, tie-in, or sectional shutdown operations.
Full-Port Design with Minimal Flow Loss
The internal full-bore structure eliminates flow restrictions and pressure drops, ensuring stable gas or water transmission with high flow efficiency across long-distance pipeline systems.
Leak-Free Integrated PE Construction
The valve body is manufactured from the same polyethylene material as the pipeline itself, combined with precision-engineered sealing components for superior airtight performance. The sealing system meets high-level gas pipeline standards for underground applications.
Excellent Corrosion & Weather Resistance
Unlike metal valves, the all-plastic PE structure resists rust, scaling, chemical corrosion, soil acidity, moisture, and UV exposure. The valve is designed for a service life of over 50 years in buried pipeline installations.
Strong Fusion-Welded Connection
The PE Double Bleed Ball Valve can be directly connected to PE pipes through butt fusion or electrofusion welding, eliminating flange joints and bolted weak points while improving overall pipeline integrity.
Smooth & Reliable Operation
The quarter-turn 90° operating mechanism ensures fast opening and closing with low operating torque. Even after long-term underground service, the valve remains smooth and resistant to sticking.
Maintenance-Free Performance
With no lubricated metal components and minimal wear parts, the valve requires virtually no routine maintenance after installation, helping reduce long-term operating costs.
Compliant with International Gas Standards
Manufactured in accordance with GB15558.3 and EN1555 standards, the PE Double Bleed Ball Valve is suitable for municipal gas infrastructure, urban pipeline upgrades, and high-standard utility engineering projects.
