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. 

丹富斯数字锁定平衡阀概述：             数字锁定平衡阀、流量平衡阀作用

SP系列数字锁定平衡阀，是液体管路流量调节阀，主要应用于工业和民用建筑采暖管网系统。其作用是方便、有效、准确的调节流量。解决管网系统中存在的高低、冷热不匀问，水力失调问题。由于该阀具有开度显示和锁定功能，只要在各支路及用户入口装上适当规格的数字锁定平衡阀，并用智能仪表进行一次性调试后锁定，将系统的总水量控制在合理范围内，从而克服了“大流量、小温差”的不合理现象。               数字锁定平衡阀、流量平衡阀作用

　　随着用户对节能要求和服务质量要求的愈来愈高，在供暖和空调系统中，用平衡阀取代以往用于调节的节流孔板、闸阀和截止阀，势在必行。平衡阀也可用于工矿事业单位其它需要调节流量的液体管路系统。
