Vallet valve mubisanzwe mumyanya ibiri- fungura kandi hafi. Nkigenzura ibisabwa neza kandi bisabwa ibipimo bya gihamye, nyamuneka hitamo valve nyinshi; Z3CF bitatu-bisanzwe bifungura valeve ya solenoid, hamwe nubwoko butatu bwibintu: Gufungura gato, gufungura rwose kandi bifunze; Zdf - z1 / 1 guhuza valvelnoid ya milnoid hamwe nuzuye gufungura, bifunguye, bifunguye, bifunguye, byuzuye bifunguye ubwoko bune. Igihe Cyiza: bivuga igihe ibimenyetso byamashanyarazi byashyizwe cyangwa byaciwe kugirango birangize ibikorwa bya valve nkuru. Gusa inkingi ya plannotiction ya solenoid irashobora guhindura igihe cyo gufungura no gufunga kimwe, kidashobora gusa kuzuza ibisabwa kugirango bigenzurwe gusa, ahubwo bikarinda ibyangiritse kumazi. Agaciro katewe no kumyenda ya Leakage nicyiciro rusange cyubukungu.
