Functional Overview
The Parker XRD103S35-K5844 valve provides hydraulic circuit protection by allowing fluid to bypass between actuator ports when pressure exceeds a set limit.
This function prevents shock loads, cavitation, and mechanical damage, ensuring smooth and safe hydraulic operation in demanding applications.
The built-in RDH103S38 cartridge delivers fast response and stable pressure relief characteristics, maintaining precise control even under fluctuating load conditions.
Applications
• Marine Hydraulic Systems: For steering, stabilizer, and winch control protection.
• Offshore Equipment: Pressure protection in cranes, valve actuators, and drilling hydraulics.
• Industrial Machinery: Used in heavy-duty presses, test benches, and automation systems.
• Mobile Hydraulics: For loaders, excavators, and hydraulic actuators where load reversal occurs.
• Ship & Dock Equipment: Essential for hydraulic ram, hatch, and deck machinery safety circuits.
Product Features
• Cross over design allows pressure equalization between actuator sides.
• Built-in Parker RDH103S38 cartridge ensures fast and stable response.
