Umahluko ophambili phakathi kweevalves ze-pneumatic kunye ne-hydraulid boocenoid kuludwe lwamanzi lulawulo olulawulayo kunye noxinzelelo apho basebenza khona:
Uhlobo lwe-fluid:
I-Pneumatic Souaumadic Valves: Ezi zilawula ukuhamba kweumoyaokanye ezinye iigesi. Ziqhelekile ezisetyenziswa kwiinkqubo apho umoya usetyenziswa njenge-fluid esebenzayo.
I-Hydraulic Soulnoid valves: Ezi zilawula ukuhamba kwei-fall, i-oils, phantsi koxinzelelo oluphezulu. Iinkqubo ze-hydraulic zihlala zisetyenziselwa i-- izicelo zomsebenzi njengoomatshini, iinkqubo zokuphakamisa, kunye noomatshini bokushicilela.
Uxinzelelo:
I-Pneumatic Valvers: Basebenzauxinzelelo oluphantsi, ngesiqhelo malunga ne-0-10 ibha (0-150 psi).
I-hydraulic valves: BasebenzaIngcinezelo ephezulu kakhulu, rhoqo kuluhlu lwe-70-50 bar (i-1 000-5,000 psi) okanye ngaphezulu.
Izicelo:
I-Pneumatic Souaumadic Valves: Ihlala isetyenziswa kumashishini njenge-automation, ukupakisha, kunye neerobhothi apho kuchanekile, ulawulo olukhawulezayo lokuhamba komoya luyafuneka ukuze ufumane ulungelelwaniso.
I-Hydraulic Soulnoid valves: Isetyenziswe kumashishini njengoKwakha, iZithuthi, kunye neMveliso, apho iphakamileyo khona-} Uxinzelelo lwe-fluid lufuneka ukuba luphakamise okanye lutyhile.
Ubungakanani kunye nokuqina:
I-Pneumatic Souaumadic Valves: Ngokubanzi incinci kwaye ilula kakhulu ngenxa yeemfuno zoxinzelelo ezisezantsi.
I-Hydraulic Soulnoid valves: Ezi zidla ngokuba yi-bulksier kunye neqhinga elingaphezulu lokujongana noxinzelelo oluphezulu kunye neemeko ezinzima kwiinkqubo ze-hydraulic.
Ngamafutshane, i-pneumatic valve zenzelwe iinkqubo zomoya okanye zegesi ezinoxinzelelo olusezantsi, ngelixa i-hydraulic valves zakhiwe iinkqubo eziphezulu.
