Eickhoff Shearer Hydraulic Pilot Valve Control Unit | Part #: C 088151 00

Description

Eickhoff Shearer Hydraulic Pilot Valve Control Unit | Part #: C 088151 00 Product Overview
This product is an original Eickhoff hydraulic pilot control unit from Germany, part number C 088151 00. In electro-hydraulic proportional control systems, this module serves as the core interface component, receiving weak electrical command signals from the main controller (such as C 087850 00) and outputting a proportional pilot hydraulic oil pressure. This precisely drives the displacement of the main directional valve spool, ultimately controlling the speed and position of the actuator cylinder (such as the height adjustment cylinder). Its performance directly determines the response speed, stability, and positioning accuracy of the coal mining machine’s automatic drum height adjustment and body posture adjustment.

Core Functions and Advantages

Precise Electro-Hydraulic Signal Conversion: Built-in high-precision solenoid valves and pressure sensors ensure that weak control current is linearly and reliably converted into stable hydraulic pilot pressure, achieving refined and automated control of the hydraulic system.

Improved Efficiency and Safety: Rapid and accurate response ensures the drum automatically adjusts to changes in the coal seam, improving mining efficiency and reducing top/bottom cutting accidents; its reliability avoids the risk of drum runaway due to control failure.

Modular Diagnosis and Maintenance: Adopting an integrated and modular design, if hydraulic malfunctions such as sluggish action, unresponsiveness, or unstable pressure occur, this unit can be replaced for quick troubleshooting and repair, significantly reducing downtime.

Adaptability to Harsh Working Conditions: Designed to meet the stringent vibration and moisture-proof standards of mining equipment, it can operate stably in high-vibration, dusty underground environments.

Typical Applications and Fault Indications

Applicable Equipment: Widely used in intelligent coal mining machines employing electro-hydraulic proportional control systems, such as the Eickhoff SL and EDW series.

Common Symptoms When Replacing This Module:

Automatic drum height adjustment function fails or operates sluggishly.

Hydraulic action exhibits “creeping” or instability during manual or automatic control.

The system reports fault codes related to pilot pressure.

After troubleshooting, the main controller output was confirmed to be normal, but the hydraulic actuator remained unresponsive.

Quality and Service Commitment: Every control unit we provide is a genuine Eickhoff part or a remanufactured part certified by the original manufacturer, ensuring that its conversion characteristics and pressure range are fully matched to the original equipment. We provide detailed technical parameter support and installation guidance, dedicated to helping you restore the precise hydraulic control performance of your equipment.
