3 HV 0 General Optimised performances and integration of the greatest number of functions are the objectives planned and achieved through the development of the HV 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. heir operation is based on the proportional hydraulic principle, e.g. keeping pressure loss constant through a variable section. he HV spool can assume an infinite number of positions making the crossing areas infinitely variable, thus regulating the flow in relation to the pressure difference (Δp) throughout the entire operating range. y means of logical selection, an LS signal (feedback) is taken from the highest pressure ports and sent to the pump flow regulator through the LS port so thath when a main spool is activated the pump regulator well adjust the displacement, so thath, the set different pressure between and LS is mainteined. he pressure compensation provided by the two-way pressure compensators installed on each element, allows multiple operations to be performed at the same time without reciprocal effects. With HV proportional directional valves program revini Fluid ower is committed to supplying products that meet the ever encreasing demands to suit different market applications. 0 revini Fluid ower - ll rights reserved. rinted in Europe. he technical features supplied in this catalogue are not binding and no legal action can be taken based on such material. revini Fluid ower will not be held responsible for information and specifications which may lead to error or incorrect interpretations.

4 HV 0 Mineral oil hydraulic fluids ll mineral oil fluids are more or less suitable for use. he 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. he requirements described above are generally met by the normal mineral oil fluids designated as HL and HVL according to DIN. Ecological hydraulic fluids Considering the minimum requirements according to DIN, the HV can also be used with vegetal oil hydraulic fluids HG (cole or rape oil) without particular precautions. Vegetal-based fluids can be mixed with mineral oils; however, it should be recalled that if the oil is changed, only the part consisting of the vegetal oil is biodegradable. he polyglycol biodegradable oils HG or synthetic phosphoric ester biodegradable fluids HDR can be used with the HV, replacing the usual gaskets with those made with FM (Viton). herefore, when ordering, we recommend to indicate the use of the HV with these types of synthetic fluids. It should also be pointed out that the synthetic fluids cannot be mixed with mineral oils. Hydraulic fluid filtering It has been widely demonstrated that efficient hydraulic equipment operation depends to a great extent on the degree of contamination of the circulating oil. oday, users require hydraulic plants to have: high performances operation precision sensitive controls reduced maintenance expenses without giving up extended plant service life. Carefully considering these requirements, it can be understood that specific filtering measures are needed with highquality filtering elements to satisfy such conditions. he maximum degree of contaminations for particles tolerated in HV proportional directional calves cannot be greater than contamination class 9 according to NS 8 (0/8/ according to ISO 0). his required contamination class is generally achieved using filters with a retention capacity of ß0 00. Our experience suggests that a pressurised filter with a nominal rating of nominal 0 µm [787 µin] or absolute 0 µm [9 µin] is suitable to maintain the required oil cleaning parameters. In addition, it is always recommended to use pressurised filters with a clogging indicator. he HV are equipped with some built-in filters which are not suitable to filter the oil of the entire hydraulic circuit, but only some pilot lines order to protect some important components of the HV against large-sized contaminating particles. he internal filters of the load sensing line and the low-pressure line are easy to replace and are available as spare parts.
