Stop And Stop Check Valve

A combination of two valves, one a stop valve, the other a stop check valve, either in the same body, or in separate bodies bolted together, used to control the admission of feed water to a boiler, to prevent the return of water or steam from the boiler, and to provide a means of shutting off the feed line between the stop check valve and the steam drum or economizer.
