Boiler Feedwater Control

Boiler feed valves are part of high-pressure water pumping systems and include three main applications:

1.Recirculation: Maximum tightness and energy dissipation under high-pressure drops.

2.Flow Control: Minimal pressure drop at max flow and pressure control at low flow.

3.Line Filling: High rangeability to cover the full pump range.

Challenges and Difficulties

High energy dissipation and precise control at varying flow rates.

Ringo’s Solution and Advantages

Ringo provides a complete range of 3595 globe control and 3599 axial control valves covering all three services:

• Recirculation: 3595 Multicyl with soft seat (Class VI) ensures long service life.
• Flow Control: 3599 axial valves provide high capacity and low-flow regulation.
• Line Filling: 3595 high-rangeability valves with multistep can achieve ratios up to 1:200, reducing the need for parallel valves.
