First, the digital lock balance valve product overview
SP45F, SP15F digital lock balance valve is a kind of regulating valve with digital locking special function. It adopts DC type valve body structure, has better equal percentage flow characteristics, can distribute flow reasonably, and effectively solve heating (air conditioning). The problem of uneven temperature and temperature at room temperature exists in the system. At the same time, the pressure drop and flow rate can be accurately adjusted to improve the liquid flow state in the pipe network system, achieve the purpose of pipe network liquid balance and source conservation. The valve is provided with opening degree indication, opening degree locking device and pressure measuring small valve for flow measurement. As long as the balance valve of appropriate specification is installed in each branch and user inlet, and the special intelligent instrument is used for one-time debugging and then locked, The total water quantity of the system is controlled within a reasonable range, thus overcoming the irrational phenomenon of “l(fā)arge flow and small temperature difference”. This product is ideal for heating systems. It can be installed on the water supply pipe or on the return pipe. Generally, we recommend to install it on the return pipe, especially for the high temperature loop. For the convenience of debugging, it should be installed on the return pipe and installed with the balance valve. Back) The water pipe does not have to be equipped with a shut-off valve.
