Valve disc self-balancing design, open and close is not affected by pipeline pressure, can be closed completely.

Manual Balancing Valve Working Principle

By changing the clearance between the water valve core and valve seat (opening), adjust Kv valve flow capacity (valve) to change the flow resistance of flow through the valve in order to achieve the purpose of flow adjustment, the role of the object is the resistance of the system, eliminate the resistance unbalance phenomenon in the system, thus to new water allocation proportion according to the design and calculation of balance, each branch in proportion to increase or decrease at the same time.

Manual Balancing Valve Installation and Commissioning

There are two methods of selection. The first is to use the software for calculating positive moisture content. The design flow Q and the design pressure difference ∆P are input to obtain the size and balance pre-set position of the balance valve. In order to obtain better accuracy, it is recommended that the positioning of the balance valve be at 50-90% of the opening degree; Secondly, when the design flow Q is known and the design pressure difference ∆P is known, the Kv value can be calculated by the formula, and then the proper balance valve size and predetermined parameters can be selected from the Kv value table. For specific use, please consult ZECO Valve Group.
