Logic elements Section overview This section gives basic specifications for Eaton logic element threaded cartridge valves. ts purpose is to provide a quick, convenient reference tool when choosing these valves or designing a system using these components. All cartridges have hardened and ground spools, and/or honed sleeves, poppets and sharp-edged ground steel seats. This provides an excellent product that is dirttolerant, has reliable seating, and is suitable for fast cycling with long life. These cartridges provide the system designer with a versatile range of elements for use in HC packages for controlling pressure, flow and direction of flow. The range includes: Pressure compensators (Section H) Pressure compensators with priority and bypass outlets (Section H) Differential pressure sensing elements The correct selection of these products can enhance machine performance, shorten the design process and minimize manufacturing costs of manifold blocks. Dfferential pressure sensing elements DPS For controlling pressure, flow or direction (including - and 4-way bridge circuits) the DPS is used with the aid of external pilot operators. The DPS elements are function building blocks which respond to pressure differential signals, providing the capacity to switch or modulate flows up to 0 L/min (80 USgpm) and pressure to 50 bar (5000 psi). The choice of pilot arrangements related to DPS variants can minimize the number of construction holes in a manifold, simplifying design and reducing costs. All poppet type DPS elements have recently been upgraded to 50 bar (5000 psi). Flow compensators PCS (Section H) An essential component of a pressure compensated flow control which, with an external fixed or variable orifice, provides the required compensated flow characteristic. Excess flow is diverted at maximum system pressure. Excess fluid upstream must be diverted e.g. through a relief to tank. Pressure compensator with priority and bypass outlets PCS4. Similar in function to the PCS. The major difference is that excess flow is diverted at priority flow pressure, instead of at maximum system pressure, as is the case with PCS compensators. The excess flow can pass to a secondary circuit or to tank. Eaton Hydraulic Screw-in Cartridge Valves (SiCV) E-VLSC-MC00-E6 January 08 www.eaton.com -5

LE40 - Logic element Spool type with control cartridge cavity 50 L/min (95 USgpm) 50 bar (5000 psi) Operation With a pilot valve fitted the valve will only open when flow is allowed across the orifice in the middle of the spool. Flow passing across this orifice will cause there to be a pressure difference that acts over the full area of the spool to move it back against the spring that biases it closed. By controlling the pressure in the spring chamber you can control the pressure at which the valve opens. Features Very versatile in its application using hardened and ground spool and sleeve giving minimal internal leakage and long life. High flow and pressure rating increases the variety of applications into which it can fit.

When used with a / solenoid valve the combination allows control of flows to 50 lts/min (95 US gpm). With a pilot relief valve or a proportional relief valve the element becomes a high flow pilot style relief. With a needle valve an on/off function is achieved. The outlet flow would normally go to tank because back pressure will act on the pilot cartridge to increase the switching pressure.

Flow passing across this orifice will cause there to be a pressure difference that acts over the full area of the spool to move it back against the spring that biases it closed. Performance data By controlling the pressure in the spring chamber you can control the pressure at which the valve opens. The vent port can be used as a remote control port to provide two pressure operation or a dump facility. Features Very versatile in its application using hardened and ground spool and sleeve giving minimal internal leakage and long life. High flow and pressure rating increases the variety of applications into which it can fit. With small modifications to the spool the valve can be used in load sensing circuits or as a compensator for by-pass pressure compensated flow controls.
