Sliding Type Spectacle Google Valve

Sliding Type Spectacle Google Valve

The sliding type spectacle google 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.

The complete silidind google valve is contained between the flanges and no parts project beyond the face of the flanges. The bore of the google valve is completed unrestricted. A drain can be provided for periodic flushing. A clean bore also reduces pressure loss through the google valve. In the event that the google valve is inserted in a brick-lined main, special steel liners backed with insulating material can be supplied. Since sufficient column strength is contained within the spectacle google valve, no additional support is required as the google valve becomes a section of the main.
