FUNZIONMENO La valvola è un compensatore di pressione a tre vie, ad azione diretta, realizzato in versione modulare con superficie di attacco rispondente alle norme CEO e ISO. Svolge la funzione di mantenere costante la caduta di pressione ( p caratteristico) tra la via e alternativamente le vie e. Viene normalmente utilizzato in abbinamento alle valvole direzionali a comando proporzionale in modo da realizzare controlli di portata indipendenti dalle variazioni di pressione. La selezione della pressione di pilotaggio sulle vie e viene eseguita automaticamente mediante una valvola di ritegno bistabile incorporata nel compensatore.
