Load Lowering Control Valve

Load Lowering Control Valve

Hydraulic valves for safe and precise operation of booms, arms and buckets in hydraulic excavators

Designed for hydraulic excavators, our load lowering control valve (also known as an anti-burst valve) is used for safe and stable operation of booms, arms, buckets, and attachments. It effectively prevents uncontrolled load movement or drifting, significantly enhancing equipment safety and operational reliability during demanding excavation tasks.

Features
  • Modular design with a compact structure, delivering safe and reliable load control
  • Minimizes hydraulic shock during opening and closing, ensuring consistent pressure control
  • Multiple flow capacity options, adaptable to different installation requirements and equipment types
  • Compliant with ISO 8643 standards, ensuring safety and compatibility in excavator applications

Yes, our load lowering control valve is specifically designed for excavator booms, arms, buckets, and attachments. It effectively prevents uncontrolled load movement or drifting, enhancing both operational safety and reliability.

Absolutely. With a maximum working pressure of 350 bar, our load lowering control valve is designed to dampen vibration and absorb impact energy, preventing excessive hydraulic shocks. This reduces the risk of sudden piston rod movements and helps avoid hose loosening or bursting during heavy-duty breaker operation.

Our valve is built with a modular design and is available in multiple flow capacity options, supporting both pipe-mount and flange-mount installations. This makes it suitable for various equipment types and assembly requirements across multiple applications.
