Overview

The GJ41X-6L pinch valve is a wear-resistant industrial valve specifically designed for large and medium-sized mining, metallurgical, chemical, and pneumatic conveying systems. This product series offers a wide specification range covering DN25 to DN400, effectively meeting diverse process requirements from branch line regulation to main pipeline shutoff. With a nominal pressure of 0.6 MPa and an operating temperature up to 85 ℃, the valve maintains stable opening and closing performance over extended service periods. The valve body is available in three material options: lightweight aluminum alloy, high-strength cast iron, and cast steel, making it broadly adaptable to harsh conveying media such as slurry, various abrasive materials, and dry/wet dusts. Relying on the unique rubber hose squeezing shutoff principle, this series demonstrates exceptional sealing and erosion resistance in applications with high abrasion and high particle content. Its full-bore flow path design ensures minimal fluid resistance and outstanding anti-clogging characteristics, making it an ideal control component for mineral processing, power plant dust removal, and building material industries.

Feature

Wide Diameter Range and Triple Material Options: The diameter spans from DN25 to DN400, with valve bodies available in aluminum alloy, cast iron, and cast steel, allowing flexible selection based on medium corrosivity and operating pressure to meet diverse industrial requirements for lightweight construction, pressure resistance, and cost-effectiveness.
Rubber Hose Squeezing Sealing Structure: Utilizing an internally reinforced rubber hose sleeve as the sole sealing and shutoff element, the valve achieves zero-leakage shutoff by external screw handwheel or actuator squeezing the hose. The full-bore flow path eliminates dead zones and fluid accumulation, ensuring smooth passage of slurry and dust media without compaction or buildup.
Superior Wear and Erosion Resistance: The thick-wall rubber hose lining inside the flow path features excellent elasticity and memory recovery, effectively absorbing impact energy from the medium and delivering significantly longer service life than metal-sealed valves in high-concentration slurry and dry abrasive conveying applications.
Broad Medium Adaptability: Depending on specific medium characteristics, various rubber hose materials including natural rubber, neoprene, and EPDM are available. The valve not only reliably cuts off conventional water and gases but also effortlessly handles slurries, pulverized coal, limestone powder, cement, and various chemically mixed materials containing particulates.
