Reliable globe valves for the West African food industry
The project:
Building a state-of-the art pasta production with globe valves from KSB
- Boiler section:
This process area places high demands on valves due to continuous exposure to steam and hot water at elevated temperatures and pressures. Valves must ensure precise pressure control, withstand thermal stress, and maintain safe, reliable operation during uninterrupted, round-the-clock production. - Chiller section:
In the chiller section, stable temperature control is critical. Valves are required to operate reliably with chilled water or refrigerants, respond accurately to load changes, and prevent temperature fluctuations that could compromise product quality or process efficiency. - Treatment section:
The treatment section requires valves to handle a combination of air, water, and chemical media under varying process conditions. High precision and repeatability are essential to ensure accurate dosing and consistent treatment results, directly impacting hygiene standards and final product quality.

The challenge:
Reliable flow control under continuous operation
- Consistent cooling in the chiller section:
After cooking, pasta must be cooled evenly and at consistently low temperatures to prevent quality deviations. This requires accurate regulation of chilled water flow under low-pressure conditions. The challenge lies in maintaining stable cooling performance throughout continuous operation, as even minor temperature fluctuations can affect product quality. Low-pressure valves are therefore required to ensure smooth flow control while reliably handling the low temperatures essential to the manufacturing process. - Uniform drying in the treatment section:
The drying process depends on precisely controlled airflow to achieve uniform moisture removal. Operating under low-pressure conditions, valves must regulate air volumes accurately and consistently over long production cycles. Any variation in airflow can result in uneven drying, directly impacting texture and overall product consistency. High control accuracy and repeatability are therefore critical requirements in this section.

Integrated valve technology from KSB
Used products
BOA-H
Bellows-type globe valve to DIN/EN with flanged ends, with on/off disc or throttling plug, standard position indicator with colour coding for identification of valve design, replaceable valve disc; bellows protected when valve is in fully open position; seat/disc interface made of wear and corrosion resistant chrome steel or chrome nickel steel.
BOA-MP
Measuring pipe with integrated ultrasonic sensors for identifying flow direction and measuring volume flow rate and temperature, sensors not in contact with fluid handled, constant measuring accuracy independent of minimum differential pressures. Stationary monitoring by means of BOATRONIC 100 MOD (24 V AC/DC, Modbus) of flow direction and volume flow rate; optional measurement of supply and return temperature, thermal output and quantity of heat. Mobile measurement of flow direction, volume flow rate and temperature using the BOATRONIC 100 measuring computer (rechargeable battery powered).
