HPV310 PROPORTIONAL DIRECTIONAL VALVES Technical Catalogue January

General Optimised performances and integration of the greatest number of functions are the objectives planned and achieved through the development of the HPV valves, a range of the latest generation of proportional directional valves that perform two simultaneous functions: directional control and flow control that is unaffected by load variations. Their operation is based on the proportional hydraulic principle, e.g. keeping pressure loss constant through a variable section. The HPV spool can assume an infinite number of positions making the crossing areas infinitely variable, thus regulating the...

Mineral oil hydraulic fluids All mineral oil fluids are more or less suitable for use. The properties required for such fluid include: • high viscosity index • low yield point • high thermal stability • high hydrolytic stability (minimum formation of corrosive phenomena inthe presence of water) • excellent anti-wear, anti-corrosion and demulsification properties. The requirements described above are generally met by the normal mineral oil fluids designated as HPL and HVLP according to DIN 51524. Ecological hydraulic fluids Considering the minimum requirements according to DIN 51524, the HPV can also...
