Apparatus and methods associated with operating a plasma torch are disclosed. According to some implementations, the apparatus and methods involve the delivery of a process gas to a shuttle valve at first and second pressures for the purpose of altering an axial position of a valve element located inside the shuttle valve. The shuttle valve is configured such that at different axial positions of the valve element the flow of process gas into the plasma torch is altered.
