In Blast Furnace and Toxic Gas applications, a simple shut-off is not enough. Maintenance teams working downstream need visual certainty that the line is physically broken.
Hubluxe Engineering’s Goggle Valves (also known as Spectacle Blinds) provide 100% positive isolation. Whether using our Fully Enclosed design to prevent hazardous gas release or the Open Type for standard service, our clamping mechanism ensures a gas-tight seal that allows personnel to enter ducts safely.
Critical Safety Feature: The valve can be designed to operate on Hydraulic and Electric Actuator that are engineered for Man-Safe Isolation. The heavy-duty body remains rigid even during the declamping cycle, preventing pipeline stress from distorting the seal face.

FAQs (Frequently asked questions)
Find detailed answers to common questions about Goggle Valves in our Knowledge centre.
A goggle valve is large diameter isolation valve sometimes also known as “100% man shutoff valve”. The goggle valve is primarily used in low pressure gas lines for handling toxic or blast furnace gases.
A Goggle Valve is used to safely isolate sections of pipeline in industrial systems, especially in Oil & gas industries – having low pressure gas lines that carries toxic or blast furnace gases.
The main purpose is to provide positive isolation, ensuring that maintenance teams can safely enter or work on downstream ducts or equipment without any risk of toxic or combustible gases entering the area.
This creates a fully “man-safe” environment.
Goggle Valves are widely used in critical areas of steel plants, refineries, coke oven gas lines, and other heavy industrial applications where complete shut-off is required.
The leading goggle valve manufacturers are few, since goggle valves operate in the most critical sections of a plant, their manufacturing process requires robust engineering, validated designs that guarantees 100% leak-proof performance. These valves must deliver a complete shutoff making it safe for carrying out maintenance work.
Hubluxe Engineering manufactures goggle valves on proven design standards, offering reliable, high-quality, and cost-effective solutions.
