Dan rich, digital locked balance valve overview: 
 
SP series digital lock balance valve, liquid pipe flow regulating valve, mainly used in industrial and civil construction heating pipe network system. Its role is convenient, effective and accurate flow adjustment. Solve the pipeline network system of high and low, cold hot uneven asked, hydraulic imbalance problem. Because the valve opening show and locking function, as long as in the selection and user entry fitted with appropriate specifications of digital locked balance valve, with special inligent instrument for the disposable lock after debugging, the system of the total water control in the reasonable scope, thus overcome the "big flow rate, small temperature difference" unreasonable phenomenon. 
 
As the user of energy saving and service quality requirements more and more high, in the heating and air conditioning system, balancing valve to replace previous used to adjust the throttling orifice plate, gate and globe valves, is imperative. Balancing valve can also be used for other industrial and mining enterprises need to adjust the flow of the fluid piping system. 

丹富斯數字鎖定平衡閥概述：             數字鎖定平衡閥、流量平衡閥作用

SP系列數字鎖定平衡閥，是液體管路流量調節閥，主要應用于工業和民用建筑采暖管網系統。其作用是方便、有效、準確的調節流量。解決管網系統中存在的高低、冷熱不勻問，水力失調問題。由于該閥具有開度顯示和鎖定功能，只要在各支路及用戶入口裝上適當規格的數字鎖定平衡閥，并用智能儀表進行一次性調試后鎖定，將系統的總水量控制在合理范圍內，從而克服了“大流量、小溫差”的不合理現象。               數字鎖定平衡閥、流量平衡閥作用

　　隨著用戶對節能要求和服務質量要求的愈來愈高，在供暖和空調系統中，用平衡閥取代以往用于調節的節流孔板、閘閥和截止閥，勢在必行。平衡閥也可用于工礦事業單位其它需要調節流量的液體管路系統。
