This article provides professional guidance on selecting gate valves for circulating water systems. Wedge-type single-disc gate valves are suitable for conventional industrial systems; they offer good sealing performance but require clean water. Flexible-disc gate valves are suitable for large-scale systems; they provide strong sealing and can withstand fluctuations in pressure and temperature. Concealed-stem gate valves are suitable for small-scale building systems; they feature a compact design and are easy to operate. When making a selection, factors such as system scale, water quality, pressure, and temperature must be considered comprehensively to ensure efficient and stable operation.
Circulating water systems are widely used in various fields, including industrial production and building HVAC. Among these, Gate Valve serve as core components for controlling water flow, and their selection is critical to system operation.
In conventional industrial circulating water systems, wedge-type single-disc gate valves are favored for their simple structure, mature manufacturing technology, and lower cost. This type of gate valve offers excellent sealing performance, effectively preventing leaks in the circulating water. Additionally, the moderate contact area between the gate and the seat results in low flow resistance during opening and closing, helping to reduce energy consumption. However, it has certain requirements regarding the cleanliness of the medium; if the water contains a significant amount of impurities, it may affect the sealing performance.
For large-scale circulating water systems with high sealing requirements, elastic gate valves are more suitable. The elastic gate automatically adjusts its contact with the seat under varying operating conditions, maintaining excellent sealing performance even when temperature and pressure fluctuate significantly. Furthermore, it can adapt to complex water quality conditions and offers strong resistance to impurities.
In small-scale building circulating water systems, concealed-stem gate valves are an excellent choice. With their compact design, minimal space requirements, ease of operation, and affordable price, they are well-suited to meet the basic needs of small systems.
In summary, when selecting gate valves for circulating water systems, it is essential to comprehensively consider factors such as system scale, water quality, pressure, and temperature to ensure the valves operate reliably and efficiently.
