PE Single Bleed Ball Valve
The PE Single Bleed Ball Valve is a specialized shut-off valve designed for polyethylene (PE) pipeline systems, featuring an integrated single-side venting and pressure release function. Manufactured from high-quality PE80 or PE100 high-density polyethylene, the valve offers excellent compatibility with standard PE gas and water pipelines.
Designed for both electrofusion and butt fusion connections, the valve combines reliable flow control with safe gas venting capabilities. Its full-port internal structure ensures smooth fluid transmission with minimal pressure loss, making it ideal for gas pipeline maintenance, pressure relief operations, sectional isolation, and utility network management.
Widely used in municipal gas distribution systems, water supply networks, industrial piping, and underground PE pipeline projects, the PE Single Bleed Ball Valve delivers long-term durability, operational safety, and low maintenance performance in demanding environments.

Key Features & Benefits
Integrated Bleed Function for Safer Maintenance
The built-in single-side vent outlet allows fast pressure release and gas venting during pipeline maintenance or shutdown operations, improving safety and reducing maintenance downtime.
Excellent Sealing Performance
The valve adopts a high-precision sealing structure that ensures outstanding airtightness and watertightness. Even under long-term operation, the valve maintains stable sealing performance without leakage.
Corrosion Resistant & Long Service Life
Constructed entirely from polyethylene material, the valve is resistant to soil corrosion, chemical erosion, UV exposure, and environmental aging. The expected service life can exceed 50 years under normal operating conditions.
Full-Port Flow Design
The internal full-bore channel minimizes flow resistance and pressure loss, ensuring stable gas or water transmission efficiency throughout the pipeline system.
Reliable Fusion Connection
The PE Single Bleed Ball Valve can be directly connected to PE pipelines through butt fusion or electrofusion welding, creating a strong and integrated pipeline connection without additional flange components.
Lightweight & Low Maintenance
Compared with traditional metal valves, PE valves are lightweight, easy to transport and install, and require minimal routine maintenance, significantly reducing long-term operational costs.
Wide Application Compatibility
Suitable for natural gas systems, municipal water supply, industrial fluid transport, irrigation pipelines, and low-corrosive media applications.
