Targeting the special working conditions at the inlet of slurry pumps in the mining industry, FNC Fengchi has developed pinch valves with a negative pressure resistant structure, successfully solving the technical problem where valves fail to fully open due to the collapse of valve sleeves caused by negative pressure.
As a core link in mining production, slurry conveying often has its weak point in the feed valve at the inlet of slurry pumps, which restricts production. Recently, our mining customers reported that other brands of pinch valves previously used at this position frequently suffered from valve sleeve collapse under negative pressure. This led to incomplete valve opening, reduced conveying efficiency, and a sharp drop in valve sleeve service life from the expected six months to approximately two months. Not only did this significantly increase replacement and maintenance costs, but it also severely affected continuous production. This phenomenon is widespread in the mining industry: ordinary pinch valves perform stably under normal working conditions but struggle to resist the negative pressure at the inlet of slurry pumps. Once the valve sleeve collapses and deforms, it can slightly reduce slurry conveying capacity and slow down production lines, or in severe cases, cause shutdowns for maintenance—becoming a prominent bottleneck restricting production continuity and economic efficiency.
To address this industry pain point, FNC Fengchi's engineers conducted an in-depth analysis of the special working conditions at the inlet of slurry pumps and successfully developed pinch valves with a negative pressure resistant structure. This product effectively resolves the long-standing issue of valve sleeve collapse and deformation that plagued customers. Its core advantage lies in the innovative negative pressure resistant design: the valve sleeve is made of high-strength, high-elasticity special wear-resistant rubber, boasting excellent wear resistance and negative pressure resistance. Additionally, a special support structure is added inside the valve body, which provides stable support for the valve sleeve when negative pressure occurs, fundamentally eliminating the risk of collapse, ensuring full valve opening throughout operation, and guaranteeing smooth and efficient slurry conveying.
Adhering to a customer demand-oriented philosophy, FNC Fengchi provides customized fluid control solutions for various harsh working conditions. Whether for slurry conveying, tailings treatment, or other severe operating environments, FNC Fengchi delivers high-performance pinch valve products to safeguard enterprises' efficient production.
