SP45, 15F digital locking balance valve is a kind of regulating valve with special function of digital locking. It adopts DC valve body structure and has better equal percentage flow characteristics. It can reasonably distribute flow and effectively solve the problem of uneven cooling and heating at room temperature in heating (air conditioning) system. At the same time, it can accurately adjust the pressure drop and flow rate to improve the liquid flow state in the pipe network system, and achieve the purpose of liquid balance and energy saving. The valve is equipped with opening indication, opening locking device and small pressure measuring valve for flow measurement. As long as the balance valve of appropriate specification is installed in each branch and user's inlet, and the special intelligent instrument is used for one-time debugging and locking, the total water volume of the system is controlled within a reasonable range, so as to overcome the unreasonable phenomenon of "large flow, small temperature difference". The product is an ideal product in heating system. The SP45 balance valve can be installed on both the water supply pipe and the return pipe. Generally, we suggest that it should be installed on the return pipe, especially for the high temperature loop. For the convenience of debugging, it should be installed on the return pipe. The water supply (return) pipe with the balance valve does not need to be equipped with a stop valve.
1. It has the function of slow opening, which can solve the traditional artificial valve closing and pump opening
2. With the function of slow closing, the closing time can be artificially adjusted to automatically realize slow closing and eliminate the water hammer
3. It has good check function and adopts rubber with good elasticity and high wear resistance as sealing material, which can be watertight after closing.
4. The movement is sensitive and will not be out of control.
5. No manual operation is required, and automatic operation is performed throughout the operation of the pipe network.
6. Convenient maintenance, no need to remove the valve from the whole pipe. Only local maintenance is needed to find out the fault cause during repair.
7. The valve inside and outside and all corrodible parts are treated with electrostatic spray, which will not rust in sewage for a long time.
8. Neutral and horizontal installation performance is unchanged.
