Solenoid Cover PC60-7 Distribution Valve Drain Pin Cover Excavator Main Control Valve Parts

I. Product Features

• Material: Most are made of cast iron or cast aluminum, while plastic alternatives are also provided.
• Shape: Small disc‑shaped or cup‑shaped structure, adopting threaded or snap‑fit connection, 20‑40 mm in diameter.
• Mounting Location: Fixed on the side or bottom of the main distribution valve, near the spool end cover and oil‑drain opening.

Functions

• Protects the drain plug component. The drain plug has a fine hole to discharge condensed water, pollutants and air inside the valve body. The outer cover keeps sand, mud, stones and iron filings from plugging the micro‑orifice or jamming the valve spool.
• Avoids hydraulic oil leakage and accidental contact. Strong vibration is generated during excavator operation. The cover presses the drain plug tightly to prevent loosening, stopping oil leakage, system pressure reduction and sluggish machine actions.
• Provides dust‑proofing and corrosion resistance. Construction sites contain large amounts of dust and muddy water. The cover separates moisture and dirt, safeguarding threads and sealing surfaces from rust seizure and disassembly difficulties during service.

Daily Maintenance & Replacement

• Inspection: Check cover looseness, cracks and oil leakage in each regular inspection.
• Maintenance: Clean dirt and sediment around the cover and fasten it securely.
• Replacement: Replace the cover in time if cracked, thread‑damaged or unsealed. Low‑cost yet indispensable; improper replacement causes valve contamination and operational defects.
