Manual Goggle Valve

ALIS Valves offers Manual Goggle Valves for industrial applications requiring positive isolation of pipelines carrying gases, fumes, dust-laden air and other compatible process media. These valves feature a spectacle-shaped plate arrangement with solid and open sections, allowing the pipeline to be either isolated or kept open for flow. The plate is operated manually using a suitable handwheel, gearbox or mechanical operating arrangement, depending on the valve design. When positioned for isolation, the solid plate provides physical separation between pipeline sections, supporting safer maintenance and shutdown procedures.

Manual Goggle Valves are suitable for compatible applications in steel plants, cement factories, power generation facilities, metallurgical industries and industrial gas handling systems. They are commonly used in ducting and pipelines carrying flue gases, exhaust gases and dust-laden air under specified operating conditions. Important selection factors include pipeline diameter, operating pressure, temperature, process media, plate and body materials, sealing arrangement, manual operating mechanism and available installation space. Selecting the appropriate Manual Goggle Valve helps support reliable line isolation, straightforward operation and safer maintenance in demanding industrial environments.
