HYDRAULIC COMPONENTS AND ACCESSORIES Pressure reducing valves, sequence valves, check valves, flow control valves, coupling units, diaphragm accumulators, filters, integrated quickaction couplings, pressure gauges, etc

Oil/oil hydraulic intensifiers are designed to convert the low pressure of the primary circuit into a higher pressure in the secondary circuit downstream from the intensifier on the basis of the intensification ratio. As soon as the hydraulic intensifier is no longer pressurized, the downstream pressure is reduced to zero, the intensifier returns into the initial position and is ready for the next working cycle. When equipped with the appropriate accessories (flow-control valves or sequence valves) hydraulic intensifiers with fixed intensification ratio are suitable for operation in highly complex hydraulic circuits with substantially higher oil volume. These hydraulic intensifiers DO NOT REQUIRE ANY LEAKAGE LINE or devices to avoid unintentional opening of the circuit. They can also be installed on fixtures that are separated from the supply during the machining cycle and remain pressurized during this phase, which implies that they do not feature the typical restrictions of continuous (pumping) intensifiers. Hydraulic elements that only operate under highpressure must not be used in the high-pressure range. The intensification volume of hydraulic intensifiers must only be used to generate high pressure for the secondary circuit and not for high-pressure supply of a circuit or partial circuit with hydraulic accumulators. With a pressure value downstream from the hydraulic intensifier that is doubled or even tripled -depending on the intensification ratio – the oil compressibility and the inevitable elastic deformation (deflection) of clamp arm and levers caused by the increased load must be considered as they partially absorb the oil volume. Correct installation and setting are fundamental prerequisites for reliable long-term operation of hydraulic intensifiers. After all components have been installed, the hydraulic circuit must be efficiently vented in order to remove any air trapped in the system. Air inclusions in the hydraulic circuit would affect the proper function of the components as well as the oil volume generated by the hydraulic intensifier. The reliable operation of oil/oil intensifiers in the long run also requires efficient oil filtering. We recommend using filters with a mesh size of 20 micron or better. High-quality filters of modular design, as in-line or built-in version for the most varied applications are presented in the following section
