Introduction For over 7 years, Vickers has provided its customers with quality products and innovative solutions for all their power and motion control needs. The products featured in this catalog represent the very best in screw-in cartridge logic element valve technology. We are committed to maintaining this position by offering the most comprehensive range of cartridge valves for industrial and mobile equipment. This catalog gives basic specifications for Vickers logic elements screw-in cartridge valves. Its purpose is to provide a quick, convenient reference tool when choosing Vickers cartridge valves or designing a system using these components. ll cartridges have hardened and ground poppets and sharp-edged ground steel seats. This provides an excellent product that is dirt-tolerant, has reliable seating, and is suitable for fast cycling with long life. These Vickers cartridges provide the system designer with a versatile range of elements for use in MD packages for controlling pressure, flow and direction. The range includes: Pressure compensators (hydrostats) Pressure compensators with priority and bypass outlets Differential pressure sensing elements Flow modulated orifice cartridges The correct selection of these products can enhance machine performance, shorten the design process and minimize manufacturing costs of manifold blocks. Flow compensators (hydrostats) PS n 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 PS Similar in function to the PS. The major difference is that excess flow is diverted at priority flow pressure, instead of at maximum system pressure, as is the case with PS compensators. The excess flow can pass to a secondary circuit or to tank. Flow modulated orifice cartridges MOS The MOS cartridges are used as modulated orifices. These cartridges are particularly effective when used with an external pressure compensator (hydrostat) such as a PS or PS type. The PS provides normal pressure compensation. The PS provides pressure compensation for priority flow arrangements. The low pilot pressure required allows proportional control when used with an EPV proportional pilot relief. DIfferential pressure sensing elements DPS For controlling pressure, flow or direction (including - and -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 l/min (8 USgpm) and pressure to 5 bar (5 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.

Supporting Products Roughing Tools Roughers are basically step drills which leave. per cutting diameter and.5 above all radii for the finishing reamer, with an additional.5 depth in the cavity bottom as clearance. The roughing tool is necessary to prepare the cavity for the finishing reamer, which has not been designed for the primary forming or bottom cutting. We offer two types of roughers, one for aluminum and one for steel. The aluminum rougher is manufactured with a facet point and polished flutes. The steel rougher is supplied with a standard drill point. oth types will work in either material, however, longevity of an aluminum tool will be sacrificed when used continually in steel. avity Material Model ode ssembly Number Way luminum RT 88 8895 Steel RT S 8 8895 6 luminum RT 6 89 56585 6 Steel RT 6 S 8 88957 luminum RT 8 6558 Steel RT S 86 56676 Way Short S luminum RT S 899 5658 S Steel RT S S 89 5667 6 S luminum RT 6 S 8 6558 6 S Steel RT 6 S S 85 5667 S luminum RT S 8 8895 S Steel RT S S 87 56675 Way luminum RT 87 8895 Steel RT S 87 8895 6 luminum RT 6 87 88958 6 Steel RT 6 S 875 56588 luminum RT 876 56589 Steel RT S 877 56677 Finishing Tools These finishing tools have been designed as precision reamers for finishing operations only. They are not intended for primary forming or bottom cutting operations. Vickers recommends that a finishing tool only be used in a properly roughed hole. Failure to conform to this practice will produce unsatisfactory size and finishes and possibly break the tool. avity Material Model ode ssembly Number Way luminum / Steel FT S 85 5658 6 luminum / Steel FT 6 S 88 56586 luminum / Steel FT S 88 88958 Way Short S luminum / Steel FT S S 8 56678 6 S luminum / Steel FT 6 S S 88 88956 S luminum / Steel FT S S 88 88959 Way luminum / Steel FT S 85 56588 6 luminum / Steel FT 6 S 88 56657 luminum / Steel FT S 885 8896 7

Hydraulic fluid must have the correct balance of cleanliness, materials, and additives for protection against wear of components, elevated viscosity, and inclusion of air. Essential information on the correct methods for treating hydraulic fluid is included in Vickers publication 56 Vickers Guide to Systemic ontamination ontrol available from your local Vickers distributor or by contacting Vickers, Incorporated. Recommendations on filtration and the selection of products to control fluid condition are included in 56. Recommended cleanliness levels, using petroleum oil under common conditions, are based on the highest fluid pressure levels in the system and are coded in the chart below. Fluids other than petroleum, severe service cycles, or temperature extremes are cause for adjustment of these cleanliness codes. See Vickers publication 56 for exact details. 8
