Hydraulic control slow closed ball valve(spherical valve)
一, Product overview

Hydraulic control slow closed ball valve with hydraulic slowly-closing butterfly valve control of all the benefits at the same time, make up for the large diameter hydraulic slowly-closing butterfly valve control can bear high pressure and high pressure water head to head of the butterfly valves are of great flow resistance coefficient. Ball valve flow resistance coefficient is almost zero, the body part can choose ball valve and ball valve, suggested that ball valves for the pressure PN40 above.

Hydraulic control valve is suitable for the working condition of high pressure water head hydro power station, installed on the turbine before, as the turbine inlet valve. Can be truncated before turbine pressure water, slowly-closing function can effectively eliminate pipeline water hammer, when there is a failure in the guide vane, can shut down automatically hydraulic control valves, prevent turbine runaway, guarantee safe operation of the equipment,

The hydraulic control valve has the function of hydraulic control butterfly valve with can be used as a distributed control system (DCS) of a central control unit, by simply unscrewing the valve control box knob switch to the remote and linkage, through the remote operation can complete valve, by-pass system, the linkage of the hydraulic turbine operation, the operation processes are completed by control of the programmable controller (PLC) in the cabinet, intelligentize degree is high, stable operation.

Hydraulic control slow closed ball valve is a combination of hydraulic control of intelligent control and ball valve's major advantages:

1, with the lowest flow resistance (actual 0);

2, it has the same rotated 90 degrees. Ball valve just has to rotate 90 degrees operation and small rotational torque can be closed tight.

Smooth the body cavity with equal cross section of the nominal diameter for medium resistance is very small, straight flow channel,

3, in the full open and full closed, the ball and seat sealing surface and the dielectric isolation, so the media does not cause across the valve sealing surface erosion;

4, compact structure, light weight, can think it is the most reasonable valve used for low temperature medium system structure;

5, body symmetry, especially welding body structure, well under pressure from pipeline;

6, close a can bear high pressure difference;
