Natural Gas Transmission & Distribution
As natural gas is widely used in urban energy systems and industrial fuel supply, valve-based transmission and distribution networks are evolving toward longer distances, higher safety standards, and reduced maintenance intervention. Reliable gas pipeline valve performance is essential for long-term system stability and safety.
How We Support Your Project
- Fully welded ball valves designed for underground and long-distance gas transmission systems
- API 607 fire-safe sealing structure for high-risk gas applications
- Anti-static and extended stem configurations for pipeline safety requirements
- Wide DN15–DN2500 coverage for mainline and branch gas network control points

District Heating Networks
District heating valve systems play a key role in energy delivery efficiency and heating stability, operating under continuous thermal cycling and long service conditions. For operators and EPC contractors, valve reliability directly impacts heat loss control and long-term system efficiency.
How We Support Your Project
- Direct buried fully welded ball valves for pre-insulated heating pipelines
- Carbon-fiber reinforced PTFE seat system for thermal expansion compensation
- Stable sealing performance across up to 5000 operating cycles
- Lockshield and customized heating valve configurations for network balancing

Water Treatment & Distribution
As urban infrastructure upgrades and industrial water demand continues to grow, water transmission systems require higher reliability and longer service life. Whether in municipal water supply, treatment plants, or industrial circulation systems, stable flow control equipment is essential for continuous operation.
How We Support Your Project
- Complete valve range including ball valves, gate valves, check valves, butterfly valves, and strainers
- Compatible with DIN, ANSI, and GB international standards
- Material and sealing customization based on water quality conditions
- Suitable for pumping stations, transmission pipelines, and treatment facilities
Proven Valve Supply Partnership in District Heating Projects
Leader Brass LLC, Ukraine's leading district heating valve brand with operations in Kharkiv, Kyiv, Dnipro, and Ternopil, consolidated its standard and custom valve sourcing into a single supplier: HAOGUANG.
Standard ball valves ship within 6 weeks; custom orders carry no minimum quantity and average 8 weeks from drawing to dock — a supply chain that has remained consistent through every heating season.
