Function
Symbol and Circuit Features
In model Cmodel Cmodel Cmodel Cmodel C the tank port is separated from the by-pass channel.
The symbol is for a 2-spool block with hydraulic operation.The spools are always arranged in parallel circuit.
High pressure mobile control blocks Type MO are directionalcontrol valves of monoblock designThey give fine control of the speed and direction of an oil flow.The valves are optionally operated hydraulically, electro-hydraulically or, on enquiry, mechanically.
They basically consist of the housing (1), control spool (2), withbuilt-in check valves (3) (for spool types 001), operatingelement (4), return element (5), built on anti-cavitation valves(6) (optional) and built-on secondary pressure relief valves (7)(optional).The 6/3-way valves combine the function of a 4/3-way valvesand a 2/2-way valve.In the unoperated condition, the control spool (2) is held instarting position by the return spring or detent (12).In this position the connection from pump to services is closed,the 2/2-way section is open and allows fluid to flow withoutpressure from P to T.If control spool (2) is moved out of its starting position, theconnection from the pump to the services is opened viametering notches and at the same time the 2/2-way section isthrottled by means of further similar notches (negative overlap).Pump pressure increases. When the pressure at the serviceport is reached, the check valve (3) in the spool opens andfluid begins to flow to the serviced unit. As the control spool(2) continues its movement, fluid is gradually fed from the 2/2-way line to the service port (fine control).
Spool StrokeSpool StrokeSpool StrokeSpool StrokeSpool StrokeThe spool stroke is divided into approx. 30% control landoverlap and 50% fine control range, while the remaining strokeserves to create the full opening.The overlap and a low spool tolerance serve to reduce internalleakage. Due to the large fine control range, the services can
be sensitively controlled.
Control Characteristics, Operating ForcesControl Characteristics, Operating ForcesControl Characteristics, Operating ForcesControl Characteristics, Operating ForcesControl Characteristics, Operating ForcesUniform quality of the control characteristics and low operatingforces are achieved by optimum design of the meteringnotches and individual grinding of the control spool to closetolerances.
Counterbalance SpoolCounterbalance SpoolCounterbalance SpoolCounterbalance SpoolCounterbalance SpoolThis spool is used for the control of hydrostatic drives ontracked vehicles as a fully automatic motion control device inboth directions of operation. Down-hill travel with cavitation-free operation is achieved by controlling the meter-out openingdependent upon the inlet pressure.
Easily Serviced DesignEasily Serviced DesignEasily Serviced DesignEasily Serviced DesignEasily Serviced Design– Primary pressure relief valves (10) are designed as screw-in
cartridges.– Secondary valves (anti-cavitation and/or pressure relief
valves) are designed as stacking elements.– Primary and secondary pressure relief valves can therefore
be interchanged without dismantling the block.
– Corrosion of the return elements is prevented, as the returnsprings (11) and detents (12) are oil immersed.
– In order to remove the control spool, only one cover need beremoved per spool. In valves with mechanical operation,cover (8) is removed and for hydraulic operation, cover (9) isremoved.
Notes on setting the primary and secondary pressure reliefNotes on setting the primary and secondary pressure reliefNotes on setting the primary and secondary pressure reliefNotes on setting the primary and secondary pressure reliefNotes on setting the primary and secondary pressure reliefvalves.valves.valves.valves.valves.The setting of the stated pressure values is made as follows:– direct operated pressure relief valves at a flow of 2 to
3 L/min.– pilot operated pressure relief valves at a flow of 10 L/min.
The 4th spool of a 4-spool block can be arranged in tandemcircuit if required.In this model, the pump port to the 4th spool is blocked whenthe free by-pass of the previous spools is closed when one ofthese is operated.

Secondary valves of various sizes cannot be used individually on MO-22 and 32, they must be used in pairs per spool. The useof secondary valves Types T, R, S and cover plate U on adjacent spools in size MO-22 is not possible. As an aid to decidingwhich secondary valves should (and can) be used, please see page 17.*See also pages 15 and 16 (items 1 and 2).
