| The Atwood & Morrill Cold Reheat Check is a reliable, sturdy valve that protects the High Pressure (HP) Steam Turbine from
damage caused by reverse flow during unit trip. In newer Rankine and Combined Cycle plants the Cold Reheat Check Valve must
alsoaccommodate the increased demands of a Turbine Bypass System and isolate the HPTurbine Exhaust when the bypass is in use. |
APPLICATIONS
- Rankine and Combined Cycle Power Plants with Reheat
- Prevents Reheat Steam from Returning to Turbine on Trip
- Simplifies Hydrotesting of the Reheater.
- Protects the High Pressure Turbine Exhaust from Bypass Steam and Water when the Turbine Bypass system operates.
- Isolates High Pressure turbine exhaust when auxiliary steam is supplied to the IP turbine in a combined cycle unit, to
synchronize the steam turbine generator or start the gas turbine on a single shaft machine.
FEATURES
- Proven, Swinging Disc Design
- Wide, Flat, Non-jamming Seats for Tight Seal
- Closure Assisting or Double Acting Air Cylinder
- Smooth Flow Passages for Low Pressure Drop
- In Line Maintenance through Bolted Top Cover
- Inclined Seat for Short Travel & Quick Operation
