Overview of Balance Valve

Balance valve is a kind of special function valve, which is different in function and place. In some industries, because the medium (all kinds of flowable substances) has a large pressure difference or flow difference in each part of the pipeline or container, in order to reduce or balance the difference, valves are installed between the corresponding pipelines or containers to regulate the relative balance of pressure on both sides, or to achieve flow balance by means of flow, the valve is called balance valve.
Balance Valve Parameters
Nominal pressure: 1.6 MPa
Applicable temperature: 0-120 C
Applicable medium: water, oil and other non-corrosive liquids
Flange Standard: GB/T 17241.6 GB/T 9113
Test standard: GB/T 13927 API 598
Performance Characteristics of Balance Valve
1. Ideal regulation performance.
2. Cut-off function.
3. Open state display of 1/10 circle.
4. The theoretical flow characteristic curve is equal percentage characteristic curve.
5. Patented open-close locking device.
6. Corresponding to the flow coefficient of each circle, as long as the pressure difference between the two ends of the valve is measured during commissioning, the flow through the valve can be easily calculated.
7. Polytetrafluoroethylene and silica gel seals with reliable sealing performance.
8. The internal components are made of YICr18Ni9 or copper alloy, which has strong corrosion resistance and long service life.
9. Internal lifting valve stem, without reserving operation space.
10. It is a combination valve.
Function of Balance Valve
Balance valve is a kind of special function valve. It has quantitative measuring and regulating functions. When debugging the system, the debugger can adjust the balance valve through human-machine dialogue with the special intelligent instrument to realize the hydraulic balance of the system.
It has good flow regulation characteristics, and the relative flow has a linear relationship with the relative opening. Some valve opening indicators, small reading is 1_of the full opening of the valve. There is a reliable opening locking memory device, the valve can be restored to the original locking position after the opening changes. With cut-off function, it is not necessary to install the stop valve when the balance valve is installed.
