INTRODUCTION:

The Models SP, SPK and SSK Monoblock Directional Control Valves may be purchased with many combinations of spools, spool positioners and relief options to meet the desired job specifications or applications. The following paragraphs describe the 3 valve models and their respective options with references to the parts illustrations in Section IV in this manual.

• In some cases, identification of a specific part or component may only be made by comparision with these parts illustrations. MODEL SP DIRECTIONAL CONTROL VALVE (Refer to Figure 4-1) The Model SP 1-, 2-, or 3-spool Valve can be identified by the number 2701, 2702 or 2703 stamped on the housing.
• This is a parallel circuit valve. The open center passage is closed off when the spool is fully shifted and hydraulic oil will flow directly to the power core passage, making oil available to all work ports. If two or more spools are fully shifted at the same time, the oil will follow the path of least resistance, and the hydraulic cylinder or the hydraulic motor with the lightest load will begin to function first.
• The hydraulic oil can be divided so that it will flow to two or more functions by metering the spools. The parallel circuit is the most commonly used circuit in mobile equipment because more than one function can be operated at the same time at random in the valve bank assembly.
