a distributor of hydraulic directional control valves from Roquet for truck and other mobile applications, HAW offers slice and monoblock valves, all rated to 350 bar (5000 psi).
These hydraulic directional valves are designed for applications with high peak pressures and have high-strength cast-iron bodies.
Typical applications in which the valves are highly successful include hook and skip loaders, 2 and 3 way tipper trucks, forest cranes, etc. In these applications, the valves are normally hand
operated and are also available as air operated or proportional units. 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.
Advantages:
Closed centre and HPCO adaptors available
Spools hard chrome plated
Load checks on each section
Low internal leakage compared with many competitors
Lots of spool positioning systems and special versions
