[0025] The preferred embodiments of the utility model will be described in detail below with reference to the drawings, and the utility model will be further described.

[0026] Firstly, the oil cylinder control valve group according to the embodiment of the utility model will be described for use in hydraulic control equipment, and the application scenarios are very wide. Figures 1-6

[0027] As shown in the figure, the oil cylinder control valve group of the embodiment of the utility model comprises: Figures 1-6

[0028] The valve block 1 is provided with a first oil port A, a second oil port B, a third oil port M, a fourth oil port T and a fifth oil port P; the first oil port A is connected with a rodless cavity of an oil cylinder, the second oil port B is connected with a rod cavity of the oil cylinder, the fourth oil port T is connected with an oil tank, and the fifth oil port P is connected with a pump outlet;

[0029] The throttle valve 2 is arranged on one side of the valve block 1 and is in communication with the valve block 1;

[0030] ​​Flow valve 3, which is disposed on the top of valve block 1 and connected to valve block 1;
