Goggle Valves are used to positively isolate downstream media flow. They are typically used in 20" (DN 500) to 72" (DN1800) diametre lines. They provide 100% " Man Safe" shut-off.
The SchuF Cam-Goggle valve is a tried and tested unique line blinding valve design. It incorporates the functionality of Fetterolf proprietary Cam-Set technology and the reliability of almost 100 years of SchuF custom valve design. Together they produce a line blinding system that ensures 100% absolute positive downstream shut off. The valve is designed to be "Man Safe".

Goggle Valve Industries & Applications
Goggle valves are frequently found in the Petrochemical, Steel, Pulp and Paper, Maritime and Oil & Refinery industries.
Positive pipeline close/off is vital in many piping systems to assure safety of personnel working on downstream equipment, particularly when flammable, toxic liquids or gases could seep past a closure. A Goggle valve is mandatory to comply with certain plant safety regulations when visible proof of shut/off is necessary.
The valve will render an absolute tight shut-off in blast furnace, basic oxygen, open hearth or other gas mains applications. It is designed for vertical operation in a horizontal main - or with roller support and other adaptations for horizontal operation in a vertical main.
