Complete solution for Siemens temperature control valve and Siemens electric control valve in heat exchange station of plate heat exchanger

In the process of designing and selecting bidding for the monitoring system in a heat exchange station, there are several common challenges. One of the main issues is the large load of the water-to-water heat exchange station, which leads to a larger diameter of the heat source piping network. This, in turn, affects the selection and cost of electric control valves used in the heat network control system. Siemens electric control valves are widely used in plate heat exchangers and heat exchanger systems across China. However, they also face certain limitations, such as size constraints, that can be problematic during implementation. In this article, we will explore the complete solution for Siemens thermostat valves and electric control valves in heat exchanger stations. Currently, central heating systems are increasingly transitioning to water-based networks. During the design and bidding phase for monitoring systems in heat exchange stations, it's common to encounter challenges related to the selection and cost of electric control valves. Due to the large pipe diameters involved, importing high-diameter electric control valves like DN150, DN200, DN250, and DN300 becomes expensive—often costing tens of thousands to millions per unit—and delivery times are long. On the other hand, purely domestic valves are cheaper but may not perform as reliably in heat network monitoring systems due to various implementation and bidding policy-related issues. Our company has accumulated valuable experience over the years in selecting electric control valves for thermal network monitoring projects, and we’d like to share some of these insights with you. From a perspective of brand, cost, and performance, non-Siemens options have proven to be suitable in many applications, especially in reheating and heat exchange systems. However, the challenge remains in pricing, as Siemens electric control valves are only available up to DN150. For larger sizes, alternative solutions must be sought. To address this, our company developed an assembled Siemens electric control valve system. What does "assembled" mean? It means using the Siemens electric actuator to develop and manufacture a matching regulating valve body. The specifications range from DN32 to DN250. This approach solves the issue of large-diameter electric control valve supply and ensures the required functionality in real-world applications. Most importantly, it significantly reduces project costs by about 50%.
