A Chain Wheel Operated Knife Edge Gate Valve is an industrial gate valve designed for isolation and flow control in locations mounted at height or in hard-to-reach areas. Instead of a standard handwheel, it’s fitted with a rugged S.G. Iron chain wheel mechanism, letting operators open or close the valve safely from ground level using a hanging chain. Manufactured as per the MSS SP 81 standard, it’s built for reliable performance in large-diameter, solids-handling pipelines.

Ideal for elevated or hard-to-reach installations across pulp & paper, wastewater treatment, power plants, mining, steel plants, chemical processing, and slurry-handling pipelines — anywhere large valves are mounted too high for direct handwheel operation.
The gate moves vertically to open or block flow, just like a standard knife gate valve. A chain loop connected to a sprocket wheel lets operators rotate the mechanism from a safe, accessible location. Pulling the chain raises or lowers the gate to control flow — making operation simple even for valves installed several meters above ground.
Allied Engineering manufactures these valves to MSS SP 81 standards, with rugged S.G. Iron chain wheels built for demanding industrial use. With multiple material and seat options, wide size availability, and years of experience serving critical process industries, we deliver valves that are safe, durable, and easy to operate — even at the toughest installation points.
