There is disclosed a reversing valve for use with a regenerative coke oven, in which the valve cock is lubricated, having four spaced longitudinally extending lubrication grooves that communicate with lubrication means when the valve is in one of its desired end positions, either open or closed. In a preferred embodiment, means are also provided for introducing degraphitizing air into the grooves, in certain positions of the valve cock.

Reversing valve

A coke oven adapted to be regeneratively heated by lean gas or rich gas at choice, characterized in that control flaps are disposed in air inlet chests for the coke oven regenerator and are connected through linkages to a common actuating rod extending along the coke oven battery. Reciprocation of the actuating rod in one direction or the other will open or close all flaps essentially simultaneously to rapidly change the quantity of combustion-supporting air supplied to the regenerator, depending upon whether lean or rich gas is being used.
