Drum or boiler level control is crucial at plant start-up, when the pressure differential between the Boiler Feed Pump (BFP) and boiler is very high and control is difficult. Boiler Feedwater Control Valves must achieve a smooth start-up and maintain required drum level for safe, reliable and efficient plant operation. The high pressure differential at start-up/low-load, and sensitive control requirement, requires a high-performance severe service control valve.

• DRAG® reduces costs and improves performance over the alternative two valve solution.
• The “change over” is eliminated, providing a quick, smooth start-up.
• Limits fluid velocities, controls vibration and erosion.
• Reduced plant-trip risk resulting in peace of mind and efficiency improvements regarding maintenance, revenues and fuel.
• Prevents cavitation damage.
• Seat replacement and maintenance costs significantly reduced.
• Eliminates cost of additional second valve and associated system.
• Stem packing provides low packing friction and long-term leak-free service.
• Balance seal uses split gland design for easy assembly and long service life.
• Working with our industry leading valve specialists who have completed our comprehensive Valve Doctor programme.
