Overview
The GJ41X-6C manual pinch valve is a professional shutoff device engineered for the conveyance of highly abrasive and moderately corrosive media in medium to large industrial pipeline systems. The product line covers nominal diameters from DN50 through DN500, comprehensively addressing shutoff and flow control requirements across workshop-level process branches as well as plant-wide main header pipelines. The valve is rated at a nominal pressure of 0.6 MPa and operates reliably at media temperatures not exceeding 85 ℃. The valve body is available in two material variants – carbon steel and stainless steel – allowing users to select the optimal option based on the corrosivity of the medium and site-specific anti-rust requirements. The valve is particularly well-suited for the transport of slurry, various abrasive materials, and dry/wet dust media. Its unique full-bore hose squeezing shutoff structure enables high-concentration solids-laden media to pass through without obstruction, while achieving reliable sealing through the elastic deformation of the rubber hose. It stands as an ideal pipeline control device for mineral processing, metallurgical dust collection, chemical, and building material industries.

Features
Comprehensive Medium to Large Diameter Coverage: The product range extends from DN50 through DN500, covering the vast majority of medium and large pipeline sizes encountered in industrial applications, eliminating the need for users to adopt multiple valve configurations for different line sizes.
Dual Body Material Selection: The valve body is offered in carbon steel and stainless steel. Carbon steel construction delivers excellent cost-performance for routine slurry and dust applications, while stainless steel construction is recommended for moisture-sensitive or moderately corrosive environments, effectively extending the service life of structural components.
Full-Bore Obstruction-Free Flow Path: The valve features a straight-through flow path with the same cross-sectional area as the connecting pipeline, with no diameter reduction or dead zones. Coarse particles and fibrous impurities within the medium can pass freely, greatly reducing the probability of line blockage and system operating resistance.
Wear-Resistant Sealing Hose Structure: A thick-wall reinforced rubber hose serves as the core sealing element, with manual screw mechanism actuation achieving uniform compression and release of the hose. During opening and closing cycles, the inner wall of the hose naturally forms a streamlined transition with the flow, effectively cushioning high-velocity particle impact while significantly reducing cumulative wear accumulation over repeated operations.
