Feed pump minimum flow flat gate valve

1. As a two-position valve, the flat gate valve is mainly used to control the opening and closing of the pipeline, and the gate moves up and down to complete the opening and closing of the valve; 

2. There are two types of casting and forging structures to choose from;

3. In the case of high pressure difference, the internal guide ring will not generate eddy current boost, and effectively protect the sealing surface from direct erosion and cavitation of the medium, effectively prolonging the service life;

4. The automatic sealing is realized by the pressure difference of the medium, and there is no need to apply additional axial force of the valve stem, so the closing torque is small, the operation is light and flexible, and the electric installation weight and motor power of the valve can be effectively reduced. The rod size and packing size are greatly reduced, especially for the occasion of quick opening and closing;

5. The positioning requirements of the closed position are low, and it is easy to realize the overall convenience and reliability of the sealed open and closed position;

6. Unaffected by the high and low temperature of the medium, the wedge gate will cause the valve to be stuck;

7. Built-in special spring, adapt to the requirements of different media, the working pressure range is not limited.
