Zhengzhou Free Fluid Control Technology Co., Ltd – Delivering reliable, safe, and durable valve solutions since 2008 for power, mining, chemical, and petrochemical industries.
Zhengzhou Free Fluid Control Technology Co., Ltd is a leader in the design and application of special industrial valves. Since introducing engineering ceramic valves in 2008, we have proven our products' worth in some of the toughest industrial environments.
Our valves are widely used in coal washing plants, coal power plants, alumina refineries, steel plants, petrochemicals, and wastewater treatment facilities. We export to Vietnam, Thailand, Pakistan, Malaysia, the United States, Indonesia, South Africa, Saudi Arabia, and Taiwan.
Focus on high quality, continuous improvement, outstanding service, and trust — both within the company and in customer relationships.
The value lies in designing valves that ensure reliability and safety in extreme industrial conditions.
Ideal for abrasive slurry applications in mining and power industries. Resistant to wear and corrosion.
Y-type design with flat disc for discharging and sampling media from crystallizers and tanks.
Double disc design ensures tight shut-off in high-pressure abrasive environments.
Rotating disc mechanism for precise control in fly ash and pneumatic conveying systems.
Corrosion-resistant rubber lining ideal for chemical and wastewater applications.
Welded connection for high-pressure systems requiring leak-tight performance.
Zero leakage design with full welding for pipeline integrity in critical services.
Heavy-duty design for high-pressure and high-temperature applications in oil and gas.
Prevents backflow in pumping systems, available in various materials for corrosion resistance.
PTFE-lined body for extreme chemical resistance in aggressive media handling.
Precise throttling control in steam, water, and oil systems with high cycle durability.
Engineered for high-concentration abrasive slurries in mining and mineral processing.
Our valves are trusted in critical applications across multiple industries where reliability and durability are paramount.
Tank bottom angle valves are suitable for discharging and sampling media from the bottom of crystallizers. Typically welded to the tank bottom via flange connection.
The Y-type body and flat disc design allow for full opening into the tank, minimizing residue and blockage.
Coal power plants generate large quantities of fly ash. ESP systems use our ceramic valves to effectively control and recycle ash while purifying exhaust gases.
Lightweight particles rise with stack gases, and our rotary disc gate valves ensure reliable material handling.
FGD systems absorb SO₂ and other contaminants using limestone slurry. Our corrosion-resistant valves handle abrasive slurries and by-product gypsum slurry.
We provide durable solutions for valves in scrubber towers, pumps, and slurry recirculation systems.
