The VM34NF main control valve is a high-performance load-sensitive multi-way valve, specially matched for Hitachi ZX470-5 series excavators.

Adopting mature integrated valve body structure and negative flow control technology, it features stable hydraulic output, precise flow distribution and excellent anti-overload performance. It can realize smooth compound actions of boom, arm, bucket, travel and swing, effectively improving operating efficiency and fuel economy.

Made of high-strength alloy material with precision machining, the valve core and sealing components wear resistance and durability are outstanding, adapting to heavy-load working conditions such as mining and earthwork. With compact structure, reliable sealing and low failure rate, it is an original matching core hydraulic component to ensure the stable and long-term operation of construction machinery.
