Turbine Inlet Valve Bypass

Plant setup can vary depending on plant design, geography, and size. A plant set up with a reaction turbine and penstock will usually feature two components: a Turbine Inlet Valve (TIV), also known as a guard or shutoff valve, and a Turbine Inlet Valve Bypass on the downstream end of the penstock before the turbine. The TIV prevents or allows water from entering the turbine.
