WorkingNo Pressure peaksIntermittent Pressure PeaksRegular Pressure Peaks
DesignLower operating stresses. Rigid well aligned mounting. Minimal side loading.Steady operating stresses with intermittent high stress. Some side loading.High stressed for majority of its working life. Side loading common.
Condition of FluidGood system filtration no cylinder contamination likely.Good system filtration but some cylinder contamination likely.Contamination unavoidable from internal and external sources.
Working EnvironmentClean and inside a building. Operating temperature variations limited.Mixture of indoor and outdoors but some protection from the weather.Outdoors all the time or a dirty indoor area. Wide variations in temperature, both ambient and working. Difficult service conditions.
UsageIrregular with short section of stroke at working pressures. Regular useage but at low pressure.Regular usage with most of the stroke at working pressure.Large amount of usage at high pressure with peaks throughout the stroke.

Dopo moltissimi anni di esperienza nelle applicazioni con equipaggiamenti idraulici, supportati da risultati di intensi test possiamo confermare che è necessario considerare tutte le variabili e caratteristiche operative come pressione ,velocità e temperatura per raggiungere un progwtto di tenuta ideale in linea con le aspettative operative.

Dopo aver considerato attentamente ogni prodotto, noi siamo capaci di specificare la massima temperatura e pressione entro il range di temperatura nella quale la tenuta potrà  operare in maniera sicura. Se le condizioni operative non coincidono con quelle specificate, siete pregati di  inviare i vostri dettagli al vostro ufficio commerciale Hallite più vicino.
