Main Relief Valve for Excavators SK1205 SK1005 SK1358 Overview A directreplacement main relief valve designed for excavator hydraulic systems compatible with SK1205, SK1005, and SK1358 models. Controls maximum system pressure and protects hydraulic components by opening to relieve excess pressure when needed. Key benefits Restores reliable pressure control so hydraulic systems respond predictably and perform tasks smoothly. Protects pumps, motors, and hoses from overpressure, reducing the risk of component damage. Minimizes downtime through a straightforward replacement that returns the machine to normal operation quickly. Precision fit for listed excavator models to simplify installation and reduce adjustment time. Main functions and attributes Function: Regulates and limits hydraulic system pressure by opening at a predetermined set point to divert flow away from pressure circuits. Compatibility: Explicit fit for SK1205, SK1005, and SK1358 excavator models. Construction: Precisionmachined components and robust metal housing for durable operation in typical working conditions. Performance: Engineered to provide consistent pressure relief and repeatable opening characteristics to maintain system stability under variable loads. Fit and form: Compact footprint that aligns with original mounting points for a straightforward replacement process. Practical applications and scenarios Onsite after a relief valve failure that causes erratic hydraulic pressure: the valve to restore stable operation and resume excavation activities. Preventive maintenance during routine hydraulic system servicing: fit a relief valve to maintain correct pressure limits and extend service life of pumps and actuators. Workshop overhaul or rebuild of an excavator: upgrade hydraulic control components with a reliable replacement valve to prepare the machine for resale or to service. Installation notes Designed for direct replacement on compatible models; follow machine manufacturer service procedures for removal and installation. Inspect hydraulic fluid condition and related hoses and fittings when replacing the valve to ensure system performance. Recommended installation by a qualified technician with appropriate hydraulic system experience. What makes this product stand out Modelspecific compatibility reduces fitment guesswork. Precision components deliver repeatable pressure relief behavior. Durable construction helps maintain hydraulic performance under demanding working conditions. Select this main relief valve when you need a reliable, modelcompatible replacement to restore correct hydraulic pressure control and reduce time on SK1205, SK1005, and SK1358 excavators.
