COPES-VULCAN® Turbine Bypass Valve
Copes-Vulcan HP and LP Bypass Valves prior to shipment to India

HP Bypass Valve
The performance requirements of the HP Bypass valve present one of the most arduous and critical of all valve applications, demanding specific design to withstand the high pressures and temperature cycling to which it is subjected.

The HP Bypass valve has to rapidly condition up to 100% MCR boiler outlet steam by reducing both pressure and temperature to cold reheat conditions. On some applications where there is no reheater, the steam has to be conditioned down to a level acceptable to the condenser.

Key Features
• Contract specific designs fully accommodate performance requirements.
• Multi-stage pressure profiling HUSH® Trims for active noise attenuation.
• Forged body designs up to Class 4500 with intermediate and split ratings being available.
• End connections to match pipework sizes and materials.
• Bolted or pressure seal bonnets.
• Trim removable in line through the bonnet connection.
• Integral, adjustable condensate drain and warming valve options.
• Installation in any orientation without actuator support.
• Shutoff up to ANSI/FCI 70-2 Class V.
• All methods of actuation are available

LP Bypass Valve
The LP Bypass valve is primarily a protection device for the condenser. The valve simultaneously reduces reheat steam to a condition acceptable to the condenser and is normally of a large size due to the radical increase in specific volume of the steam as it is let down to condenser pressures which are often sub-atmospheric.

Key Features
• Contract specific designs fully accommodate
performance requirements.
• Multi-stage pressure profiling HUSH® Trim for active noise attenuation.
• Forged body design up to Class 900 with split ratings available.
• End connections to match pipework sizes and materials.
• Bolted bonnets with quick change trims.
• Trim removable in line through the bonnet connection.
• Installation in any orientation without actuator support.
• Shutoff up to ANSI/FCI 70-2 Class V.
• All methods of actuation are available.
• Optional dump tubes with small hole technology for noise attenuation
