Functional description, section

2 way cartridge valves are designed as inserts for compactmanifold control blocks. The "logic" cartridge with ports A and B isinstalled within a cavity with dimensions conforming toDlN ISO 7368. A cover is mounted above the insert which functionsas a seal and control interface for the valve poppet. Dependent ontype of cover and optional pilot valve, the cartridge valve canperform directional, throttle, pressure or combinations of thesefunctions. The circuit designer can select type and size of cartridgevalve with respect to given flows within an application. Aneconomical use of space, reduction of external fluid connectionscan be achieved via logic systems.

Directional Function2 way cartridge valves consists basically of the cover (LFA...)...(1)and insert (LC...)...(2). The cover contains the control drillings,orifices, shuttles, and external directional valves as determined onspecific model types. Stroke limiting functions and directionalvalve pilot functions are also available for throttling and/orswitching functions. The insert (2) includes a bushing (3)..cap (4),sizes 16 ... 32, and a poppet (5). The poppet (5) may include adampening nose (6) or not (7). The control spring (8) provides abiasing force to close the poppet as forces A1 + A2 correspondsX = A3.

Function2 way cartridge valves are similar to check valves where a biasingspring tries to hold a poppet closed against a flow stream untilsufficient forces exist to open the poppet. Rexroth defines area A1as 100%. The annulus at "B", area A2, can be either 7% or 50%dependent on model selected. An area ratio between A1: A2 canbe either 2:1 or 14.3:1. Area A3 is the sum of A1 and A2 and ispiloted from the source "x". The pilot signal can originate from "A","B" or other external source. Since A1 + A2 equals A3, the biasing

no code = NBR sealsV = FPM seals

(other seals on request)

Attention!The compatibility of the seals andfluid has to be taken into account!

Without damping nose With damping nose

spring is necessary to close the poppet in the event all hydraulicforces are balanced.

Basically:Pressure upon areas A1 and A2 open the valve. Pressure uponarea A3 plus the spring close the valve. The resultant force (ofopening and closing forces) determines the spool position (5; 7)of the 2-way cartridge valve.

2-way cartridge valves may flow A to B or B to A. When the pilotoil for area A3 is obtained from port B external port A is closed,leak free.

Pilot valves must be ordered separately.For further details see relevant data sheet.Valve mounting bolts are included within the control cover scopeof supply.

Control cover with electrical monitoring of the closed position model ..E..(monitoring of closed spool position): dimensions in inches (millimeters)Technical data and notes are valid for all control covers withelectrical monitoring (..E.., ..EH2-.., ..EWA.., ..EWB..).

The solid state limit switch with integral amplifier switches when theclosed position is reached. This limit switch has the followingadvantages:

– No dynamic seals– Direct monitoring of the closed switched position of the valve– Long service life– Control cover and cartridge valve are included in the model
