SD11

Walvoil _Monoblock Valve _SD11

The SD11 valve is normally used on travelling and tilting vehicles, silage chopper‑mixers, and in services for cranes, compactors and car carriers. It's available in one‑section execution for circuits where power beyond and closed center is not required (SD11/1‑N).

 

 

 

 

SDM 140 - DLM 140

Walvoil _Monoblock Valve _SDM140

The versatility of the SDM140 monoblock valve makes it the perfect control device in applications involving agricultural machinery, harvesters, front‑loaders, earth moving machines, skid‑steer loaders, dumpers, shovels, telescopic boom fork lifts, industrial vehicles and mobile cranes. It's also available in Load‑Sensing signal version DLM140.

 

 

SD14

Walvoil _Monoblock Valve _SD14

It's normally used to control motors for brush cutters, silage chopper‑mixers and medium‑size log splitter. Equipped with an ON/OFF electro‑hydraulic control kit, it is mounted on skid‑steer loaders.

 

 

SD18

Walvoil _Monoblock Valve _SD18

Thanks to its robust construction, the SD18 valve is used in agricultural machinery to control motors for large brushcutters, and in industrial vehicles such as trash compactors and drain systems.
