Boiler

For boiler feedwater line:

• Automatic minimum flow valves to protect boiler feedwater pumps.
• Leak-off type control valve to ensure minimum flow of boiler feedwater pumps.
• Free flow reverse current check valve to protect boiler feedwater pumps.
• Boiler feedwater control valves with high rangeability (combining disk stacks and perforated cage in the same valve).
• Parallel slide gate (anti thermal-binding) main boiler feedwater isolation valves.
• Free flow reverse current check safety valves for high-pressure preheaters.
• Electronic steam level switches for high-pressure preheater condensate wells.
• Polishing plant for reduction of condensed water conductivity through microfiltration.
• Condensate extraction pump.

For boiler:

• Isolating diverting or modulating three way valve for uninterrupted economiser flow transfer.
• Main steam valve and main feedwater valve: isolation by parallel slide gate valve, (anti-thermal binding).
• High-performance parallel slide gate valves for purges.
• Level control: level monitoring/interruption with level safety device in the boiler drum (dome).
• Desuperheating: see different types in products.
