English term or phrase: frictional matched spool and sleeve assembly
This range of bolt on valves offers very sensitive speed and directional control. One frictional matched spool and sleeve assembly is offered with two alternative means of actuation.
CONFIGURATION
As standard these valves can be supplied with either EQUAL POWER OR BIASED POWER spools, the latter is suitable for hoisting applications (normal power for lifting - reduced power for lowering).
The direction of reduced power must be stated when ordering CW or CCW, when viewed on the output shaft of the motor or geared motor.

Explanation:
Rotary valve spool/sleeve assembly. The spool rotates and translates within the sleeve bore.
:
The design consists of a stationary sleeve and a rotating/translating spool. The sleeve (Fig. 3) is designed to replace part of the pump housing in order to minimize the dead volume between the pump outlet and the spool. The outlet flow of the pump is directed to tangential nozzles that port fluid to the inner diameter of the sleeve bore and into the inlet section of the spool.

Spool valves are the usual choice for directional control, because they can be manufactured to give complicated connections in a simple sliding mechanism.
:
Spool valves have two elements: a cylindrical barrel in which slides a plunger. Port blocking is provided by lands or full diameter sections on the spool, separated by waisted sections which provide port interconnections through the barrel.
:
Seals, which may be O-rings or square section, are positioned between the valve spaces, so that there is a seal between each port and on the outside of the two outer ports (see Figure 5).

Directional control valves (DCVs) are one of the most fundamental parts of hydraulic and pneumatic systems. DCVs allow fluid flow (hydraulic oil, water or air) into different paths from one or more sources. DCVs will usually consist of a spool inside a cylinder which is mechanically or electrically actuated. The position of the spool restricts or permits flow, thus it controls the fluid flow.

Wegeventile dienen in der Fluidtechnik (Pneumatik und Hydraulik) dazu, den Weg für das Arbeitsmedium (Druckluft, Hydraulikflüssigkeit) zu sperren oder die Durchflussrichtung zu ändern. Die Ventile unterscheiden sich nach folgenden Hauptmerkmalen:
1. Bauart des Steuerelements, z. B. Schieber, Ventilkegel
2. Anzahl der Schaltstellungen
3. Art der Betätigung, z. B. elektrisch (Elektromagnet), pneumatisch, hydraulisch, mechanisch, manuell
4. Anzahl der Durchflusswege
5. Anzahl, Größe und Art der Anschlüsse, z. B. Nennweite, Gewinde

disagree  Tony M: You have been misled by Asker's parsing: in this case, the 'spool and sleeve' are 'frictionally matched' (a hyphen in the source text would have helped!) It means the sizes have been carefully matched to achieve a snug 'friction fit'.
