Huadu Valve - High-Performance Valves Exclusively for Natural Gas Industry

As a core clean energy field, the natural gas industry imposes extremely high standards on valve safety, sealing, temperature/pressure resistance, and impact resistance. Huadu Valve specializes in the natural gas sector, developing a full range of special valves covering the entire industrial chain—from exploration, purification and long-distance transmission to urban gate station pressure regulation and terminal use. These valves stably adapt to natural gas, LNG and other media, and cope with extreme conditions such as high pressure, low temperature and harsh outdoor environments. Backed by an intelligent production system and strict quality control, every valve meets international and domestic standards, ensuring safe and efficient operation of the natural gas industry.

Core Product Series for the Natural Gas Field

To meet the full-scenario needs of the natural gas industry, Huadu Valve has developed four core special products that balance performance stability and industry compliance:

1. Natural Gas Special Floating Ball Valve

- Material Selection: Forged from high-quality 304, 316L stainless steel and Monel alloy, it resists natural gas erosion and atmospheric corrosion, suits LNG low-temperature storage/transportation, and meets all low-temperature valve technical requirements.

- Sealing Guarantee: Imported hard sealing material with 0.008mm ground sealing precision achieves two-way zero leakage, passes international fugitive emission testing (ISO 15848-1), and eliminates gas leakage risks.

- Specification Adaptation: Customizable from DN10 to DN1000 (PN10~PN320), accurately matching pipeline needs of long-distance transmission, urban gate stations and pressure regulating stations.

2. Natural Gas High-Pressure Slab Gate Valve

- Built with solid one-piece forged steel body and upgraded seat design, this valve can reliably work under pressure up to 25MPa. It fits well for high-pressure gas mining and long-distance pipeline transportation, fully meets API 6D requirements.

- The valve stem is finely processed with anti-rust treatment and reliable sealing structure. It operates smoothly freely in cold and high-pressure working conditions, won’t get stuck or clogged even after frequent use.

- All items are made and tested in accordance with API 6D and GB/T 19672 standards. We provide full set of pressure resistance, explosion-proof and tightness test papers, totally qualified for mainstream engineering projects worldwide.

3. Natural Gas Low-Temperature Throttle Globe Valve

- Adopts professional low-temperature resistant materials and matched sealing parts, stably serves in temperature range from -200℃ to 150℃. Great choice for LNG storage, gasification and delivery lines with good cold resistance.

- Practical throttling structure makes gas pressure and flow adjustment easy and accurate, widely used for pressure control, flow measurement and gas pipeline matching work at gas stations and chemical sites.

- We supply valve bodies in WCB carbon steel, stainless steel and low-temperature alloy as you need. These materials resist erosion and corrosion effectively, bring longer service time and lower maintenance cost on site.

4. Natural Gas Slow-Closing Check Valve

- Safety Protection: Slow-closing buffer structure weakens water hammer damage, prevents gas backflow, and protects compressors and pressure regulating valves.

- Quality Control: 100% inspection of all valve bodies/discs via patented equipment (Patent No.: CN117686214A), with pressure resistance, explosion-proof and low-temperature tests to eliminate quality hazards.

- Easy Maintenance: Simple structure with no vulnerable parts reduces medium turbulence and pipeline resistance, suitable for unattended and remote operation.

Full Working Condition Adaptation Range

Natural Gas Exploration and Purification

Suitable for high-pressure sand-containing medium transmission in exploration and desulfurization/dehydration/acid gas removal in purification, withstanding trace corrosive components to ensure stable operation.

Full Process of Liquefied Natural Gas (LNG)

Adapts to LNG storage, loading/unloading, long-distance transmission and gasification station connection, with international-standard low-temperature resistance and reliable sealing to avoid leakage risks.

Natural Gas Long-Distance Transmission and Terminal Distribution

Widely used in long-distance pipelines, gate stations, pressure regulating stations and terminal distribution, resisting harsh outdoor environments, corrosion and explosion, suitable for outdoor/underground installation.
