Black Excavator Foot Pedal SK75 Foot Operated Hydraulic Control Valve YN30V00070F2

Excavator Foot Pedal Valve Travel Pedal Valve SK75 Foot Operated Hydraulic Control Valve

Core Functions

• Travel Control (Key Function): Left and right foot pedals correspond to two side tracks. Pressing pedals drives forward or reverse travel, with pedal travel determining moving speed.
• Attachment Regulation: Controls on‑off status and working motions of breakers, quick couplers, hydraulic shears and other attachments.
• Motion Fine‑tuning: On select models, it adjusts boom and arm positions precisely or works with joysticks to complete multi‑action operations.
• Neutral Safety Protection: Automatically resets to neutral when foot pressure is removed, disconnecting pilot pressure to avoid mis‑operation.

Working Principle

• It is a pilot control valve delivering low‑pressure signals rather than directly powering travel motors.
• Non‑operating status: Automatic neutral return, no pressure output and machine remains static.
• Operating status: Spool movement outputs hydraulic signals to the main multi‑way valve to control travel motor action.
• Release status: Spring‑driven reset stops all controlled movements immediately.

Common Faults

• Uneven traveling: Internal leakage or sticking spool in single‑side pedal valve
• Pedal fails to rebound: Broken spring or clogged spool
• Weak travel performance: Low pilot pressure or worn valve assembly
• Hydraulic leakage: Aging sealing elements or impaired valve body
