What It Is / How It Works

This RC high pressure hydraulic rotary valve block is a valve block with a 4mm nozzle and 1 to 8 channels, made for excavator and engineering vehicle models. It is an aluminum alloy valve block that comes as one piece.

Who It's For / Use Cases

Hydraulic valve blocks like this suit hobbyists who build or upgrade radio-controlled excavator and engineering vehicle models. They suit builders who want a compact hydraulic control unit that can grow as more functions are added.

How to Use / Care

1. Keep the use pressure within 8Mpa.
2. If the system has no central oil return function, use the valve block with the overflow valve from the store.
3. When the cylinder reaches its longest or shortest stroke, the overflow valve opens the pressure relief valve to drain oil into the tank.

How to Choose

Start with the channel count, because each hydraulic function on a model needs its own channel. Check the nozzle size and hose connector type in Product Specifications against the hoses on your model. If you plan to add functions later, the upgrade path lets the block grow from a smaller channel count.
