Overview
The GJ41X-6Z manual gray cast iron pinch valve is a reliable shutoff device engineered for the conveyance of solids-laden media and general corrosive fluids in medium to large industrial pipeline systems. This product line covers a nominal diameter range from DN50 through DN400, offering flexible adaptability from workshop-level process branches to plant-wide main header pipelines. The valve is rated at a nominal pressure of 0.6 MPa and maintains stable operating performance at media temperatures not exceeding 60 ℃. The valve body is manufactured from high-quality gray cast iron, providing excellent compressive strength and casting precision. It is broadly adaptable to diverse challenging conditions including slurry, liquid abrasives, dry and wet granular mixtures, and general corrosive media. Relying on the full-bore rubber hose squeezing shutoff principle, this valve delivers outstanding clog resistance and sealing reliability under high solids content, large particle size, and mildly chemically aggressive conditions, making it an ideal pipeline shutoff device for mineral processing, chemical piping, building materials, and environmental protection industries.

Features
Wide Diameter Coverage: The product range extends from DN50 through DN400, fully 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.
High-Quality Gray Cast Iron Body: The valve body is constructed of high-strength gray cast iron, offering excellent casting density and deformation resistance. It maintains structural stability under long-term operation at 0.6 MPa working pressure while delivering favorable cost-effectiveness, making it suitable for widespread industrial deployment.
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 Hose Squeezing Sealing Mechanism: 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. The inner wall of the hose features excellent elastic memory recovery characteristics, effectively absorbing particle impact energy and extending service life.
