Cam-Goggle Valve
Goggle valves are very similar to line blind valves. They are generally used in Gas Blast Furnace or other low pressure applications (typically less than 1 bar / 25 psi). They can be enclosed or open design and can be made up to 64 inches.
60" Goggle Valve - Type I - Open
Cam Google Valve Models
There are two basic types of Goggle valve available - Type I Open and Type II an enclosed variant. The open type is for all intents and purposes no different than a sliding (Cam-Slide) or swinging (Cam-Set) line blind mechanism, except that it may be specified according to specific operating conditions rather than to an ASME pressure class - 150#, 300# ect.
So a Goggle valve can be designed to 25 or 50 psi for example. This results in a lighter and more compact design that a full class line blind, which is significant when the google valve size is 40 inches or above..
Enclosed Cam-Goggle
The enclosed Cam-Goggle valve enables the spectacle plate to be changed without releasing any medium to atmosphere.They are man safe and 100% leak tight. The enclosure can however not exceed 2.5 bar.
