FNC Fengchi is one of China’s earliest enterprises engaged in the design and manufacture of pinch valves, and also the lead drafting unit of the national industrial standard for Pinch Valves. Developed and produced by Fengchi, the Fengchi pinch valve realizes fluid on-off control and flow regulation based on the flexible squeezing principle, and is specially designed for handling abrasive, corrosive and particle-containing media. With core advantages including compact structure, reliable performance and easy maintenance, the product is widely used in various industrial fields such as chemical engineering, mining, electric power and water treatment, effectively solving fluid control pain points under complex working conditions and providing solid guarantee for the stable operation of production systems.
Product Structure
The FNC Fengchi pinch valve mainly consists of four core components, which work in coordination to ensure stable and efficient valve operation:
1.Valve Body
Manufactured from cast iron, cast steel or stainless steel, the valve body combines high robustness and corrosion resistance, offering reliable support and protection for internal components.
2.Rubber Sleeve
As the core functional component of the valve, the FNC Fengchi rubber sleeve adopts a special three-layer structure (inner layer, outer layer and reinforced fiber layer) and is formed through an integrated vulcanization process, featuring stable structure and excellent toughness. With over 20 material options including natural rubber and fluororubber, it can be precisely customized to match medium properties, working pressure and application scenarios, directly determining the service life and sealing performance of the product. In addition, worn sleeves can be directly replaced with new ones, enabling low-cost equipment maintenance, ensuring continuous and stable production and greatly reducing downtime losses.
3.Actuator
Available in four driving modes: pneumatic, electric, manual and hydraulic, the actuator achieves accurate valve opening/closing and flow regulation, flexibly adapting to diverse demands of automated production lines and manual control scenarios.
4.Connection Parts
Designed in compliance with standard specifications, the connection parts fit perfectly with various pipe sizes, providing tight and firm connections to effectively prevent fluid leakage and ensure safe and trouble-free conveying.
Typical Application Cases
Relying on its outstanding core properties, the FNC Fengchi pinch valve is widely applied in multiple industrial sectors including chemical engineering, mining, electric power and water treatment. The following typical application cases intuitively demonstrate the product’s advantages:
1.Metal & Mining Industry
In an iron ore concentrator, the slurry conveying medium contains a large amount of ore particles with extreme abrasiveness. The plant selected FNC Fengchi pinch valves with wear-resistant rubber sleeves. These valves withstand long-term slurry scouring without clogging or leakage, effectively solving the industry-wide pain points of easy wear and blockage of conventional valves, and ensuring continuous and stable operation of the slurry conveying system.
2.Water Treatment Industry
A municipal wastewater treatment plant adopted FNC Fengchi pneumatic pinch valves for the conveying and control of particle-containing media such as sludge and gravel. The wear-resistant rubber sleeves effectively resist scouring damage from particulate media, the zero-leakage design prevents sludge seepage, and the self-cleaning function reduces clogging, significantly improving wastewater treatment efficiency while lowering equipment maintenance frequency.
3.Chemical Industry
A chemical enterprise required conveying and control of corrosive acid and alkali solutions, and chose FNC Fengchi pinch valves equipped with fluororubber sleeves. Fluororubber delivers superior corrosion resistance to withstand acid and alkali erosion, and the zero-leakage design avoids equipment damage and safety hazards caused by corrosive medium leakage, perfectly meeting the harsh working conditions of chemical production.
4.Lithium Battery New Energy Industry
A CATL power battery production base applied customized clean-type FNC Fengchi pinch valves in the automated conveying of positive and negative electrode slurries such as lithium iron phosphate and conductive graphite. Equipped with FDA-certified clean and wear-resistant hoses with mirror-finished inner walls, the valves completely eliminate metal ion precipitation, adapt to high-frequency opening/closing of production lines, and double the service life of hoses compared with imported valves, effectively ensuring consistency and safety in cell production.
5.Photovoltaic Industry
In a quartz sand purification project in Shandong Province, the medium is a mixture of quartz sand, oxalic acid and hydrochloric acid, featuring harsh working conditions and high automation requirements. Over 600 sets of heavy-duty pneumatic automatic control FNC Fengchi pinch valves were selected for the project. Fitted with wear-resistant and corrosion-resistant composite sleeves and integrated with sleeve wear detection, the valves monitor service life in real time, perfectly adapting to severe working conditions and supporting stable project implementation.
6.Paper Industry
A large paper mill needed precise pulp flow control during the pulping stage and selected FNC Fengchi wear-resistant pinch valves. Their full-bore unobstructed design effectively avoids pulp clogging, the wear-resistant sleeves endure long-term pulp scouring, and precise flow regulation ensures stable paper quality, greatly reducing equipment maintenance frequency, downtime and boosting production efficiency.
7.Cement Industry
Handling highly abrasive powder and slurry mixtures is common in cement production. FNC Fengchi pinch valves efficiently process such materials with minimal internal damage, stably adapting to various harsh scenarios in cement production and ensuring smooth production processes.
