Acting hydraulic valve

hydraulic valve block is a pressure oil operations automation components used, which is controlled by pressure control valve pressure oil is usually used in combination with electromagnetic pressure valve can be used for remote control station oil, gas and water pipeline system off. Commonly used in clamping, control, lubrication oil passage. There are direct acting and pilot type of points, the use of pilot type.
Acting hydraulic valve manifold are used to control the flow direction of the hydraulic system in the oil or adjusting the pressure and flow, so it can be divided into directional valve, pressure valve and flow valve three categories. A shape of the same valve, can be because of the different mechanisms of action, and have different functions. Pressure valve and flow valve with a through-flow cross-section of throttling control the pressure and flow system, and directional valve replacement through the use of flow paths which control the direction of flow of oil. That is, although there are a variety of hydraulic valves of different types, among them still maintain some basic points in common.
