1 Static Balancing Valve Series W-JP45X-16Q Sizes: DN50-DN300 APPLICATION The Series W-JP45X Static Balancing Valve is designed for flow balancing in cooling, heating or process water systems. Its measuring points enable convenient system troubleshooting. FEATURES Accurate flow control Numerical indicator of opening rate on the handwheel Lockable set position Shut-off function achieved by handwheel Self-sealing measuring points to protect against leakage OPERATING PRINCIPLES The Series W-JP45X Static Balancing Valves can be applied in different places in a water system. When the system is under static hydraulic disorder, through manually setting the opening rate of the valves, the system s undesired resistance distribution can be changed into the desired one. This ensures that the actual flow value of every bypass or terminal matches its design value.

4 TYPE SELECTION DIAGRAM: Example of Type Selection: Q: It is needed to install a Static Balancing Valve on the bypass of an air-conditioning system. Given that the design flow is Q = 25 m3/h and the design pressure drop is ΔP = 10 KPa, select a Static Balancing Valve with proper size. A: Draw a straight line between Q = 25 m3/h and ΔP = 10 KPa, creating an intersection of this line and Kv scale in the middle, Kv=79. Based on the intersection, draw a horizontal line crossing three opening scales of differently sized valves. These three new intersections are 7.7 turns for DN65, 5.6 turns for DN80 and 2.8 turns for DN100 respectively. Since it is recommended to set the valve at around 75% opening rate, choose a Static Balancing Valve in the size of DN80.
5
6 MEASURING ACCURACY: The curve indicates the measuring accuracy of Series W-JP45X valve. Obviously, the larger the opening rate is, the smaller the Kv measuring deviation is. When the valve s opening rate is greater than 50%, the deviation is lower than 5%. Based on this, it is suggested to choose a valve with at least 50% opening rate when working under the design flow. Additionally, in order to ensure adequate on-site commissioning allowance, it is recommended to set the valve at around 75% opening rate. INSTALLATION Installation The Series W-JP45X Static Balancing Valve is usually installed on return pipe. When combined with Differential Pressure Balancing Valve, it can be used for supply pipe. Generally, when connected to an elbow or a pump, the valve must keep a certain distance from the elbow or the pump. The principle is shown in the right figure.
