Construction machinery hydraulic control check valve CKCB

The balance valve is a kind of valve with special function. There is nothing special about the valve itself, but there are differences in the use function and place. In some industries, because the medium (all kinds of flowable substances) has a large pressure difference or flow difference in various parts of pipes or containers, in order to reduce or balance the difference, a valve is installed between the corresponding pipes or containers to adjust the relative balance of pressure on both sides, or to achieve the balance of flow by shunting. This valve is called a balance valve.

1. Ideal regulation performance; 2. Excellent cut-off function;

3, accurate to 1/10 turn of the open state display;

4. The theoretical flow characteristic curve is an equal percentage characteristic curve;

5. National patented opening and closing locking device;

6. There is a dependent flow coefficient corresponding to each whole circle. As long as the pressure difference between the two ends of the valve is measured during debugging, the flow through the valve can be calculated conveniently;

7, PTFE and silica gel seal, reliable sealing performance;

8. The internal components are made of YICr18Ni9 or copper alloy, which has strong corrosion resistance and long service life;

9. Lift the valve stem internally, so there is no need to reserve operating space.

10. It is a combination valve. [1]

Among them, ZLF self-operated balance valve is a kind of valve which uses the pressure change of the medium itself to regulate itself, so as to keep the flow through the controlled system constant. It has flow indication and can be adjusted online, and is suitable for non-corrosive media such as heating and air conditioning systems. One-time test and adjustment before operation can make the system flow automatically set at the preset setting. The valve has the advantages of accurate flow adjustment, simple operation, stable operation, reliable performance and long
