Product Detail

Product Overview

The electric flow and pressure regulating valve is a kind of control valve, which works in coordination with the automatic control system and is mainly used to control the pressure in front of (behind) the valve, the flow through the valve and the liquid level in the pool. The valve works on the principle of compound hole counter flushing energy dissipation, which can reduce the high pressure in front of the valve to the low pressure behind the valve; It can also control the valve flow or the liquid level in the pool by controlling the size of the overflow area of the valve port; The valve can also be used as the discharge valve of the reservoir dam.


Product features

1. It can be adjusted automatically, with stable adjustment and small vibration;2. Small cavitation during regulation;3. Reasonable design, constant within a certain accuracy range, high adjustment accuracy;5. One valve is multi-purpose and can be adjusted and sealed;6. The end face seal is adopted, and the seal ring is not easy to wear and has a long service life;7. Control form: manual, electric, hydraulic, etc.
