GVO CO170-5576 Boom Holding Main Relief Valve Hydraulic Load Lock Counterbalance Valve for Excavator YC210 DH225-7

 Key attributes

Reliable Load Holding – Prevents Accidental Dropping
  This is the valve's most essential function. It instantly locks the hydraulic circuit in the event of a hose burst or sudden pressure loss, preventing the boom, arm, or other attachments from dropping unexpectedly due to gravity. This provides a fundamental safeguard for both operator safety and equipment protection.

Smooth, Controlled Movements – Enhances Precision
  Unlike a simple hydraulic lock that can cause abrupt stops, this counterbalance valve builds back-pressure during load lowering, providing controlled resistance. This prevents the attachment from overspeeding or dropping suddenly due to gravity, ensuring smooth, stable movements. This is particularly valuable for precision tasks such as fine grading, sloping, and lifting operations, where control accuracy is critical.
