1. Self-acting working principle with reliable operation: The valve utilizes the pressure differential changes in the controlled loop as the driving force, achieving automatic regulation through the balance of built-in springs and pressure-sensitive diaphragms (or pistons). It requires no additional power or gas source, featuring a simple structure and stable, reliable operation.
2. Accurate flow control and locking: The target flow rate can be preset and mechanically locked using a dedicated tool or handwheel on the valve body. Once set, the valve automatically maintains a nearly constant flow rate within the allowable pressure differential range, ensuring high control precision and effectively preventing over-flow or under-flow.
3. Extensive operational range: The valve features a wide adjustable flow range and adaptable working pressure differential, enabling it to accommodate seasonal variations and load fluctuations across systems, ensuring consistent flow control under all operating conditions.
4. Equipped with shut-off and measurement functions: The valve ensures reliable sealing when fully closed, functioning as a loop cutoff valve. Some models feature a measurement port on the valve body, allowing connection to specialized instruments for convenient flow rate detection without affecting valve operation, facilitating debugging and routine inspections.
5. System optimization for energy efficiency: By eliminating redundant head between loops and automatically balancing branch flow, this solution effectively reduces pump head requirements and total system energy consumption. It also minimizes commissioning efforts while enhancing overall system efficiency and stability.
