Product introduction FLOWSPEC SP45F type digital lock balancing valve is one type of regulating valve which has special function of digital lock. SP45F type digital lock balancing valve adopts straight body structure which makes the valve have better equal percent flow feature. SP45F type digital lock balancing valve has distributed flow more reasonably to resolve effectively the problem of uneven cold and hot temperature in the room existing in the heat supply (air conditioning) system. At the same time, SP45F type digital lock balancing valve can adjust accurately pressure drop and flow to improve the fluids flowage in pipeline to achieve the fluids balance in pipeline and energy saving. Because SP45F type digital lock balancing valve has open indicator, open locking device and small pressure test valve for determining flow, only need mounting proper balancing valve on the branch pipeline and user access, and then take a primary regulating on it with a special intelligent gauge, and lastly it will be OK by locking it to control the flow in the system within certain reasonable range. SP45F type digital lock balancing valve resolves the unreasonable problem of “heavy flow, small temperature difference”, which makes it as the good choice for the heat supply system. SP45F type digital lock balancing valve can be mounted on the water supply pipe, or can also be mounted on water return pipe. But, we suggest normally it be mounted on the water return pipe. Especially for the high temperature loop, it has more necessary to mount on the water return pipe for convenient repair. The pipe mounted with SP45F type digital lock balancing valve doesn’t need globe valve.
