Detailed

Characteristics:


1.The dynamic flow balance valve is composed of valve body an valve core.


2.Acting on thedifferential pressure between the front and behind of the valve is lower than the

design scope that the valve core throttle nozzle is completely exposed fromthe valve core cover

under the action of the spring. At this time, the flowarea is largest but the flow is according to the

change of pressure difference.


3. Acting on thedifferential pressure between the front and behind of the valve within thescope of

the design, the valve core was suffered from the dual action of thedifferential pressure and spring

force. So it do piston repeated movements tochange the flow area to maintain a constant flow in

the design valve.


4. .Acting on thedifferential pressure between the front and behind of the valve is higher  than the 

design scope that the valve corethrottle nozzle is completely into the valve core cover and only 

showing thefixed flow hole.  At this time, the flowarea is least but the flow is according to the change 

of pressure difference.
