SSY005379983 Main Valve Bottom Cover Plate Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

SSY005379983 Main Valve Bottom Cover Plate Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY005379983 main valve bottom cover is a core hydraulic protection component from SANY, compatible with all SANY construction machinery, including excavators, pump trucks, and loaders. Installed at the bottom of the main control valve, it seals off the chassis’s open area, protecting the main valve, hydraulic lines, connectors, valve cores, and other precision components. It prevents sand and gravel splashes, mud and water erosion, and dust accumulation, reducing problems such as dust accumulation and jamming of the main valve, rust and leakage at connectors, and valve body wear. This stabilizes hydraulic operation and maintains a neat chassis appearance.
This product is made of high-strength protective sheet material, pressed in one piece, making it sturdy, resistant to bending and impact, and suitable for heavy-duty and harsh working conditions such as mining, infrastructure construction, and earthmoving. Equipment operating outdoors for extended periods is susceptible to damage from mud and water immersion, and impacts from sand and gravel. Ordinary cover plates are prone to cracking, warping, rusting, loosening, and poor fit, allowing impurities to enter the valve body and causing hydraulic jamming, sluggish operation, oil leakage, and unstable pressure, thus affecting operational efficiency. This product features precise original factory molding and a tight fit. Standard hole positions allow for non-destructive replacement of old parts, making it suitable for routine maintenance, fault repair, and bulk stocking, effectively reducing the probability of hydraulic failures and saving on maintenance costs.
