features
1, full liquid valve volume is small, through the flow of large and no leakage, but before the switch must first pressure relief can be opened.
2. The filling valve is generally used as the oil suction and discharge valve between the hydraulic cylinder and the oil tank. In the quick running process of a large press, oil is sucked from the oil tank.Prevent the oil from the cylinder into the tank when pressurized and reverse the oil from the cylinder to the tank.It is often used in large presses and injection molding machines for filling oil into the cylinder when the oil tank, so as to achieve rapid movement in the use of small pump conditions.When the cylinder is fast-forward, a large amount of liquid is filled into the cylinder from the tank. In the process of pressurization, the cylinder can be cut off and the oil is indeed returned to the tank. When the cylinder returns, the pilot control pressure oil forces the filling valve to open, so that the oil in the cylinder is drained back to the tank.
