Our hydraulic directional control valves are designed for applications with high peak pressures and have high-strength cast-iron bodies which we cast in our own foundry.

Typical applications in which our valves are highly successful include hook and skip loaders, 2 and 3 way tipper trucks, back-hoe loaders etc.


3-way tipper

Hook loader

Skip loader

Forest crane


In these applications the valves are normally air operated (on/off or proportional). A recent development is a range of monoblock and slice valves with electro-pneumatic operation which greatly reduces fitting time as only two air lines need to be fitted per valve block (see photo below of a typical assembly). Please contact us for details.
