1. Structure and Performance
The role of a self-operated flow control valve is to ensure a constant flow rate, even amidst fluctuations in the pressure difference between the inlet and outlet of the valve . This guarantees a steady flow to the controlled object, whether it be a loop, a user, or a device in series. Self-operated flow control valves are the key to maintaining this balance. With various monikers, including self-operated flow balance valve , fixed flow valve, self-balancing valve, and dynamic flow balance valve, these valves are indispensable. Despite their structural variations, their working principles are universally aligned, focusing on maintaining equilibrium. valves share a common goal: seamless flow management.
2. Structure and Working Principle Structurally
The self-operated flow control valve sare ingeniously designed with a dual valve system, integrating a manual regulating valve group alongside an automatic balancing valve group, as illustrated in Figure 1. The manual regulating valve group is tasked with setting the desired flow rate, while the automatic balancing valve group ensures the flow rate remains unwavering.
The self-operated flow control valve manages this by the flow G=P2-P3 type for the manual control valve group. Here, Kv represents the flow coefficient of the manual control valve port, with P2-P3 denoting the pressure differential across the manual control valve port. The size of Kv is contingent upon the opening, remaining constant if the opening is fixed, thus stabilizing the flow G as long as P2-P3 stays consistent. The automatic balancing valve group adeptly controls the consistency of P2-P3. For instance, if the pressure difference P1-P3 rises, the automatic balancing valve group responds by adjusting through its pressure sensing mechanism, ensuring P1-P2 elevates to keep P2-P3 stable; conversely, if P1-P3 decreases, the group expands to reduce P1-P2, maintaining P2-P3's constancy. valve group is expanded, so that P1-P2 is reduced and P2-P3 is maintained constant.
Each opening of the manual control valve Each group seamlessly corresponds to a specific flow rate. The intricate relationship between the valve's opening and the flow rate is meticulously calibrated through rigorous test bench trials. This precision engineering is enhanced with an innovative opening display and a robust locking mechanism.
3. Performance and Features

2. Skillfully engineered to tackle the challenge of system temperature disparities, our product significantly enhances heating or cooling quality for optimal environmental comfort.
3. Expertly addresses the challenging contrast between significant pressure differences, ensuring a seamless balance from the near to the far ends of the system.
4. By optimizing system water circulation, this valve effectively decreases system resistance, promoting efficiency and sustainability.
5. Significantly reduces the design workload by eliminating the need for complex hydraulic balance calculations within the pipe network.
6. Simplifies intricate network adjustment processes, transforming them into straightforward flow distribution tasks, thus enhancing operational efficiency.
7. Effortlessly facilitates the transition between different heat sources in multi-source pipe networks, eliminating the need for cumbersome flow redistribution.
8. The flow display values undergo random calibration on a test bench, ensuring precise measurements in cubic meters per hour (m3/h).
4. Technical Parameters
1. Designed to operate effectively in medium temperatures ranging from 0-150ºC, with a working pressure difference that can be selected between 20-600 Kpa. The selection can be tailored to match the pipeline's equal diameter.
2. Available selections are also based on the valve's maximum flow rate and the applicable flow range, ensuring flexibility and adaptability in various scenarios..
5. Installation and Commissioning
1. Ensure the medium's flow direction aligns perfectly with the indicated arrow on the valve body; this guarantees optimal performance and longevity.
2. After installation, adjust the flow rate to meet the specific demands of the series pipeline;
3. Carefully verify that the pressure difference across the valve is maintained within the prescribed working pressure range;
4. Strive to prevent the valve from operating in conditions of minimal flow to ensure durability and efficiency.
5. Note that the spring cover lacks a blowdown screw; hence, regular manual blowdown is essential.
6. Adhere strictly to the standard
