The part number CLARK M.H.A SCD – 009 P NO 8057218 refers to a genuine CLARK brand hydraulic control valve, a critical component for the operation of a forklift’s hydraulic system.
Detailed Product Description: CLARK Hydraulic Control Valve
1. General Function:
This valve is the main control unit for the forklift’s hydraulic functions. The operator uses the control levers in the cabin to actuate this valve, which precisely directs the flow of high-pressure hydraulic oil to different cylinders. It controls the primary movements of the forklift, typically:
-
Lifting and Lowering the forks (Lift Circuit)
-
Tilting the mast forward and backward (Tilt Circuit)
-
(Potentially) Operating Side-shift or Attachment functions (e.g., for a clamp or rotator) if equipped.
2. Key Features & Specifications:
-
Manufacturer: CLARK, a leading original equipment manufacturer (OEM) for forklifts and material handling equipment.
-
Part Number: M.H.A SCD-009 P – This is the core model/series number for the valve assembly.
-
Identification Number: NO 8057218 – This is likely a specific casting, serial, or manufacturing lot number used for precise identification and traceability.
-
Type: Hydraulic Control Valve (Sectional Valve Bank). It is typically made of multiple stacked sections (or “spools”)—one for each function (lift, tilt, etc.)—bolted together into a single unit.
-
Construction: Made from high-strength, precision-machined aluminum or ductile iron to withstand high system pressures (typically in the range of 1500-2500 PSI for forklifts).
-
Ports: Contains multiple threaded ports for:
-
Pressure Inlet (P): Receives pressurized oil from the hydraulic pump.
-
Tank Return (T): Returns oil back to the hydraulic reservoir.
-
Work Ports (A, B, etc.): Connect via hoses to the hydraulic cylinders (e.g., lift cylinder, tilt cylinders).
-
-
Internal Components: Contains precision spools, springs, seals, and load-holding checks valves to ensure smooth, controlled, and safe operation.
