Control the directional valve in front of the hydraulic cylinder, because of some reasons of the valve body’s own design, such as when the O-valve is in the neutral position, it can keep the high pressure closed for a certain period of time.

However, due to the gap of the valve itself, internal leakage will gradually occur over time. The pressure of the enclosed hydraulic oil in the system will gradually decrease. It means that after the oil cylinder reaches the pressure, the oil station stops supplying oil, and the pressure in the oil cylinder will gradually decrease.

Generally, to solve this problem, let the system maintain pressure for a long time from several hours to dozens of hours, it is necessary to introduce a hydraulic lock, also called a hydraulic control check valve. Through the function of this valve body, the pressure of the oil cylinder can be kept constant for a long time.
