Static balance valve, also known as balance valve, manual balance valve, digital locking balance valve, dual position regulating valve, etc., changes the flow resistance through the valve by changing the gap (opening) between the valve core and the valve seat to achieve the purpose of regulating the flow rate. Its target is the resistance of the system. Static balance valve can balance and distribute the new water according to the design calculation ratio, and the various branches behind the valve can increase or decrease proportionally at the same time, still meeting the flow demand of partial load under current climate needs, playing a role in thermal balance.

Key Features:

A balance valve is a type of valve with a special function, and the valve itself has no special features, only the difference in usage function and field. In some industries, due to the significant pressure or flow differences of various flowable substances in different parts of pipelines or containers, valves are installed between corresponding pipelines or containers to reduce or balance these differences. These valves are used to adjust the relative balance of pressure on both sides or achieve flow balance through diversion methods. This valve is called a balance valve.

(1) Linear flow characteristics, that is, under the condition of constant pressure difference before and after the valve, the flow rate and opening degree are generally linearly related;

(2) Some aperture indicators;

(3) There is an opening locking device, and non management personnel cannot change the opening at will; The table connection can conveniently display the pressure difference before and after the valve and the flow rate through the valve. Although balance valves have many advantages, there are still many problems in their application in air conditioning water systems. If these problems are not solved properly, the characteristics of the balance valve cannot be fully demonstrated. The function of a balance valve is to regulate the predetermined flow rate of each distribution point (such as each building) within the system. Balance valves are installed at the entrance of each building to distribute the total flow of the heating system in a reasonable manner.
