One-stop Automatic Valve Solutions
Though small in size, valves act as the critical "throats" in the industrial chains of coal chemical and mineral processing sectors. The fluids here are far from pure — they consist of ore slurry loaded with high-hardness particles, highly corrosive chemical agents, as well as high-temperature and high-pressure gas-solid mixtures. Under such harsh conditions, every opening and closing of valves pushes material science and sealing technology to their limits.
As a dedicated player in industrial automatic control, VATTEN (Shanghai Vatten Valve) has developed a full set of automatic valve solutions featuring outstanding durability, corrosion resistance and zero leakage, tailored to the extreme operating conditions of coal chemical and mining industries. Deployed in the flotation workshop and slag discharge system of a leading Chinese mining enterprise, VATTEN valves passed a rigorous one-year field test with zero failures and zero complaints.
Three Severe Operating Conditions in Coal Chemical & Mining Industries
Valve failure in ordinary chemical projects may only cause minor leakage, while in coal chemical and mining sectors, it often leads to production shutdowns and potential safety hazards. VATTEN’s technical team conducted in-depth on-site investigations and identified three major industry pain points:
1. Severe Wear and Erosion
The black water and ash water discharged from coal gasifiers in coal chemical plants, as well as tailings slurry from mineral processing, contain massive high-hardness solid particles such as gangue, quartz and iron ore slag. For conventional valves, slag tends to get stuck between gate plates and valve seats during operation. The high-velocity slurry acts like sandpaper, quickly wearing through valve bodies and resulting in internal leakage.
2. Strong Corrosion and Scaling
Acidic gas in coal chemical conversion systems and chemical reagents used in mineral processing are highly corrosive. Meanwhile, high-concentration slurry easily accumulates inside valve cavities, causing valve jamming and incomplete closure.
3. Demands for Non-stop Continuous Operation
Facilities in these industries operate 24/7 all year round. Any unplanned downtime will incur substantial economic losses. Therefore, valves are required to deliver reliable performance over millions of operating cycles with minimal maintenance.
One-year Field Record: Wear-resistant Valves Guarding Flotation Workshops
Project Background
The dense medium flotation workshop of a major coal producer in China has long suffered from severe abrasion on medium pipelines. At cyclone feed and tailings discharge points, fluid flows at high speed with high solid concentration. Traditional domestic knife gate valves used to wear out or develop leakage after merely 1 to 2 months of service.
VATTEN Custom Solution
For this working condition, the VATTEN team recommended our core products: high wear-resistant ball valves and heavy-duty knife gate valves.
Operational Performance
- Zero leakage with original sealing performance fully maintained
- Excellent wear resistance and precise flow regulation
- No material accumulation or valve jamming
Client Feedback
"Valves at this working station used to be consumables, and we had to keep plenty of spares in stock. Since we switched to VATTEN valves, we haven’t touched a single wrench over the past year, not even tightening the packing gland. They are truly maintenance-free." The plant’s equipment director spoke highly of VATTEN products.
Continuous Innovation: Beyond Product Supply, We Co-create Value Together
One year of stable operation marks both a milestone and a new starting point. VATTEN fully understands that equipment upgrading for mining and mineral processing is an ongoing journey. Never resting on our laurels, our team keeps striving to adapt to increasingly sophisticated mineral processing techniques and complex coal chemical processes ahead.
We continuously gather on-site pain points and feedback from frontline operations. We conduct rapid product iterations based on real customer input, ranging from upgraded metal seals for ultra-high temperature working conditions to optimized valve cavity flow passages for extra-large solid particles.
Adopting the integrated model of technology-driven marketing and customized services, VATTEN accurately addresses differentiated demands across various ore types and production processes.
Proven by one year of failure-free operation in high-wear, high-corrosion and round-the-clock operating environments, VATTEN demonstrates solid technical strength. We not only supply standard valves, but also strive to be a specialized fluid control expert for the coal chemical and mining industries.
Choose VATTEN
Choosing VATTEN means more than purchasing a valve — it means gaining round-the-clock operational reliability. Moving forward, VATTEN will continue to empower China’s intelligent manufacturing with German-grade quality, and help all partners achieve safe, efficient and eco-friendly production amid the toughest working conditions.
