The CK Holliday uses several different types of valves. I’ve made the first two types to use on the model:
The main header valve is a 2″ model. It’s mounted on top of the boiler and allows steam to be supplied to the appliances in the cab.
The dual-cocks are 0.5in type. Note the funnel at the bottom that allow steam or water to exit.
Both valves were made per Lukenheimer’s specs. However, these valves get replaced time to time, so the type that you’ll see in person or in pictures will differ slightly. I am modeling the valves as they would typically appear.
