Speed Control & Metering parts diagram: 1 directional spool valve, 2 flow control cartridge, 3 valve cavity block, 4 coil spring, 5 o-ring set. 10 parts in 5 top-level items. — Speed Control & Metering parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Directional Spool Valve	1×	Proportional spool responding to joystick input, metering pump flow to open or close shear blades.
2	Flow Control Cartridge	2×	Pilot-operated flow restrictor limiting shear closing speed to 30–60 mm/s for smooth material cut.
3	Valve Cavity Block	1×	Ductile-iron or ductile-steel cavity housing the spool and cartridges with integral porting.
4	Coil Spring	2×	Helical spring of round steel wire that stores energy in compression or extension, used for suspension, return force, and preload.
5	O-Ring Set	4×	Set of elastomer rings seated in grooves to seal static or slow-moving joints against fluid and gas, sized to ISO 3601.
