Product Details

Product Overview

The electric flow and pressure regulating valve is a type of control valve. During operation, it works in conjunction with the automatic control system, mainly used to control the pressure before (and after) the valve, the flow rate through the valve, and the height of the liquid level in the tank. This valve operates based on the principle of energy dissipation through a composite orifice. It can reduce the high pressure before the valve to the low pressure after the valve; it can also control the flow rate through the valve or the height of the liquid level in the tank by adjusting the size of the flow area of the valve opening; this valve can also be used as an emission valve for reservoir dams.

Product features

1. It can be automatically adjusted, with smooth operation and minimal vibration.
2. During the adjustment process, cavitation is minimal.
3. The design is reasonable, maintaining a constant value within a certain precision range, and the adjustment accuracy is high.
4. One valve with multiple functions, capable of both adjusting and closing the seal;
5. The end-face sealing is adopted, and the sealing ring is less prone to wear, resulting in a long service life.
6. Control methods include mechanical, electrical and hydraulic.
