What are the application fields of FNC Fengchi pinch valves?

In modern industrial production, numerous working conditions are confronted with challenging problems in conveying highly‑abrasive, corrosive and high‑solid‑content slurries. Conventional valves are prone to wear‑induced jamming, sealing failure and frequent leakage. As a leading drafter of industry standards for pinch valves, FNC Fengchi has developed a full range of pinch valves including manual, pneumatic, electric and hydraulic‑driven types with core rubber liner technology. Featuring full‑bore non‑clogging performance, zero‑leakage sealing even for particle‑laden media, outstanding wear and corrosion resistance and easy maintenance, these products are widely adopted in mining & metallurgy, chemical, environmental protection & water treatment, power & steel, new‑energy, building‑material powder and many other industries, delivering reliable shut‑off, throttling and metering solutions for complex working conditions.

Mining represents one of the most critical application scenarios for pinch valves. Mining processes generate large volumes of ore slurry, tailings and flotation slurries containing hard gravel and metallic particles. Such media are highly abrasive with fluctuating pipeline pressure, placing stringent requirements on valve wear resistance.

FNC Fengchi pinch valves are widely deployed in iron, copper, gold and non‑ferrous metallurgy projects for ore slurry transportation, tailings filling and discharge, ceramic filter supporting, underflow discharging of thickeners and flotation process control. Specially‑formulated wear‑resistant rubber liners withstand long‑term particle erosion. The full‑bore structure avoids slurry accumulation and valve jamming. Large‑size electric modulating models can connect to mine DCS systems for remote flow regulation, supporting smart mine construction. Many products realize import substitution and serve large‑scale mining groups nationwide.

Chemical facilities handle diverse media including strong acids, strong alkalis, organic solvents, powders, corrosive slurries and crystallizing materials. High requirements are imposed on valve sealing and anti‑corrosion performance, as leakage may cause severe safety hazards.

Only the rubber liner of FNC Fengchi pinch valves contacts process media. Liners of EPDM, fluororubber and other materials can be selected according to medium properties, suitable for phosphorus chemical, chlor‑alkali, coal chemical and other processes. Typical applications include corrosive slurry conveyance, powder shut‑off, waste liquid & residue discharge and process batching flow regulation. Even when solid particles are trapped during closure, zero‑leakage sealing can be achieved. Without metal valve cores or seats vulnerable to chemical corrosion, the valves support continuous safe operation of chemical plants and reduce unplanned downtime.

Municipal sewage and industrial wastewater systems process sludge, lime milk, flocculants, landfill leachate and high‑solid‑content wastewater loaded with impurities susceptible to scaling. Ordinary valves easily suffer clogging and sealing‑surface wear failure.

FNC Fengchi pinch valves are applied in pump outlet shut‑off for sludge transportation, chemical dosing regulation, grid sludge discharge, sedimentation tank slag removal and waste‑water residue treatment. The straight‑through flow channel delivers self‑cleaning performance and prevents sludge and impurities from depositing. Corrosion‑resistant rubber liners resist acid‑base corrosion in sewage. For maintenance, only the rubber liner needs replacement without full pipeline disassembly, lowering operation costs and improving system reliability for wastewater treatment plants.

Flue‑gas desulfurization (FGD) systems, ash handling and coal‑slurry transportation in power plants, as well as slag slurry and dust‑removal slurry in steel smelting generate media mixed with gypsum particles, coal ash and slag featuring combined wear and corrosion.

FNC Fengchi pinch valves are suitable for desulfurization slurry pipelines, ash‑slag conveying lines and coal‑slurry systems. They resist persistent particle erosion, mitigate penetration and slurry leakage common in traditional valves, ensure stable long‑term operation of environmental‑protection facilities in power and steel plants, reduce on‑site leakages and satisfy environmental‑protection production requirements.

With the rapid growth of the new‑energy sector, lithium‑ore beneficiation, salt‑lake lithium extraction and photovoltaic slurry processing generate rising demand for wear‑resistant and corrosion‑resistant valves.

Optimized for lithium‑ore beneficiation slurry, salt‑lake brine and high‑solid‑content slurry, FNC Fengchi pinch valves adopt wear‑and‑corrosion‑resistant rubber liners. They have been supplied to leading domestic lithium‑salt enterprises and overseas new‑energy mining projects for process shut‑off, tailings conveyance and brine transportation, providing localized fluid‑control solutions for the new‑energy‑material industry.

In building‑material, ceramic, sand‑stone processing and pneumatic conveying sectors, Fengchi pinch valves perform pipeline on‑off and flow control for cement slurry, mortar, sand‑stone mud and powder materials. The full‑bore design prevents powder bridging and valve blockage in pneumatic conveying systems. Sanitary‑grade liner versions are also available for particle‑slurry control in food, light‑industry and other niche scenarios.

From traditional heavy industry to emerging new‑energy tracks, FNC Fengchi pinch valves address core pain points caused by abrasive, corrosive and particle‑laden media. Combining standardized products with customized solutions for specific working conditions, the product range covers DN15‑DN2000 with manual, pneumatic, electric and hydraulic actuators available to solve diverse complex pipeline fluid‑control challenges.
