Product Description

 

Product Description

Introduction:

The PE-Lined Steel Flat Gate Valve for Gas is a specialized valve designed for gas distribution systems, featuring a steel valve body lined with polyethylene (PE). This unique construction combines the strength of metal with the corrosion resistance of PE, making it ideal for natural gas, LPG, manufactured coal gas, and other media, particularly suited for medium- and low-pressure gas pipelines.

 

Structural features:

1. PE Lining for Corrosion Resistance: The valve interior is lined with food-grade polyethylene (PE), preventing direct contact between metal and the medium, ensuring long-term durability.
2. Full-Bore Design: Matches pipeline inner diameter for zero pressure drop, allowing for pigging (pipeline cleaning).
3.Bidirectional Sealing: Flat gate + PE soft seal ensures zero leakage (Class VI), compliant with EN 1074-3 gas valve standards.
4.Anti-Static Design: Equipped with an electrostatic discharge device to eliminate spark risks caused by gas flow.
5. Lightweight Structure: 30% lighter than all-metal valves, enabling easier installation and maintenance.
