1. Overview
The SP45F and SP15F Digital Locking Balancing Valves represent cutting-edge advancements in fluid control technology, offering innovative adjustment valve solutions. These high-performance valves are embedded with a unique digital locking functionality. They boast a direct current valve body architecture that is meticulously engineered to enhance flow characteristics, ensuring optimal and rational fluid distribution. These valves are the ultimate solution for mitigating uneven temperature distribution typically encountered in heating and air conditioning systems. In addition, they precisely adjust pressure drops and fluid flows, significantly enhancing liquid dynamics within pipeline systems. By achieving impeccable fluid balance, these valves pave the way for remarkable energy-saving results.
Both the SP45F and SP15F Digital Locking Balancing Valves come fully equipped with an intuitive opening degree indicator, a reliable opening locking device, and a precision small pressure measuring valve designed for accurate flow measurement. The installation process is straightforward: place balancing valves of the correct specifications at each branch and user entrance. Once adjusted with a specialized intelligent instrument, they should be securely locked. This guarantees that the total water volume within the system remains within a desirable range, effectively combating the notorious "large flow, small temperature difference" anomaly. The SP45F and SP15F Balancing Valves are particularly well-suited for heating systems, offering versatile installation on both supply and return pipes. However, it is generally advantageous to position them on return pipes, especially in high-temperature loops, to facilitate smoother adjustments. Supply (return) pipes with balancing valves eliminate the need for separate shut-off valveinstallations.
2. Product Characteristics
This valve is a state-of-the-art balancing valveengineered for a wide array of liquid pipeline systems. It stands out as an exemplary energy-saving valveoption. This valve features a meticulously calibrated digital display, allowing for effortless and precise adjustments to any desired position, with the ability to lock settings securely. The valve primarily serves industrial and civil building heating pipeline systems. Addressing the prevalent issue of hydraulic imbalance in some pipeline configurations, balancing valves provide an effective solution. They enable precise adjustments of pressure drops and flow rates, thereby optimizing liquid flow dynamics and achieving superior liquid balance and energy efficiency within pipeline systems. Even in dual-pipe network renovation projects, implementing this valve can yield significant energy savings and impressive outcomes.

6. The Main Connection Size: Understand the precise specifications that guarantee optimal integration and performance.
The illustration on the right showcases the flow characteristic curve of this innovative valve, highlighting its efficiency.Designed and crafted in our state-of-the-art factory, these valvesboast equal percentage characteristics. From the graph, it is evident that with a proportional change in the opening, the flow rate shifts consistently. This results in a substantial flow rate when the opening is wide, and a diminutive flow rate when narrow. Predominantly used in engineering for high-flow scenarios, the equal percentage valve is meticulously engineered to meet this specific demand. Thanks to this attribute, users can effortlessly set a desired flow rate (a feature unavailable in quick opening valvesand linear valves), allowing for easy adjustments to achieve the perfect flow state.

9. Transportation and Storage: Ensuring Longevity and Performance
1) The valve must be protected from collisions, tipping, compression, and exposure to rain or snow during transport and storage.
2) The valve should be kept in a clean, dry, fireproof, and ventilated space free from corrosive gases.
3) The packed valve should be handled with care using pallets; direct contact by forklifts or cranes with the valve body is prohibited to prevent damage.
4) Static Balance Valve Guidance: During transport and storage, keep the spool in an open state, closing is strictly prohibited to ensure stability.
5) Static Balance Valve Care: Avoid using alcohol, gasoline, or other chemical solvents to clean the valve seat or spool which may be lubricated for smooth operation.
10.Installation
1)Static balancing valve before and after the valve must ensure that sufficient length of the branch pipe section to ensure the rated flow output;
2)Check the installation position of the static balance valve according to the drawing. It is recommended to install the static balance valve on the HVAC system return pipe. At the same time, check the pipeline water flow direction and install the static balance valve strictly in the direction of the water flow arrow on the valve body.
3)Before installing the static balance valve, clean the debris in the pipeline. It is forbidden to leave welding slag, branches, stones and other debris in the pipeline to avoid damage to the valve;
4)The welding of the pipe flange cannot cause excessive deformation, and the welding Angle does not affect the flatness of the sealing surface;
5) After the static balancing valve is installed, the valve should be fully opened so that the pipeline can be flushed repeatedly until it is clean. It is forbidden to close the valve repeatedly during pipeline flushing to avoid damage
6 )After the pipe is washed clean, the static balance valve should be switched on and off several times, and check whether the counter position is "zero" when it is closed. Before the valve leaves the factory, it has been strictly
tested, and the counter should be in the "zero" position when it is closed.To replace the corresponding parts,please contact the customer service department of Shanghai Airlines;
11.Debugging and maintenance
1 The debugging of the balance valve belongs to the system debugging. If the user has debugging, please contact the customer service department of Shanghai Airlines;
2 Balance valve is life balance design, so under normal conditions of long-term use maintenance free, no wearing parts;
3 After the balance valve has been used for several years, the rubber sealing parts may show signs of damage or aging, and the rubber seat is needed.
4 When the ambient temperature is below the freezing point in winter, please take anti-freezing measures to avoid freezing the valve body.
