CHV150-300
Kama majina yanavyodokeza, vali hii ina lango linalobembea ambalo huning'inizwa juu na hufunguka kama umajimaji unavyopita ndani yake. Kifungu cha mtiririko wa laini hutolewa na valve ya kuangalia ya swing wakati disc ya valve iko katika nafasi ya wazi kabisa. Ndani ya vali, chaneli hii laini hutoa mtikisiko wa chini na kupungua kwa shinikizo. Ili valve ifanye kazi kikamilifu, lazima iwe na shinikizo la chini ili kufungua diski. Wakati mtiririko wa maji unarudi nyuma, shinikizo na uzito wa kati dhidi ya diski husukuma diski kwenye kiti, na hivyo kuzuia kurudi nyuma. Vali za ukaguzi kawaida huzingatiwa kama vifaa vya usalama au kinga.
Darasa la 150-300 Valve ya Kukagua Chuma cha Cast ni vali ya hundi iliyotengenezwa kwa chuma cha kutupwa. Imegawanywa katika darasa la 150 na darasa la 300 kulingana na darasa la shinikizo. Vipengele vyake ni pamoja na muundo rahisi, ukubwa mdogo, uzito mdogo, utendaji mzuri wa kuziba, na uendeshaji rahisi. Vali hii inafaa kwa mazingira ya shinikizo la juu na joto la juu ili kuzuia mtiririko wa maji katika mabomba. Kawaida hutumiwa katika mifumo ya bomba katika nyanja za viwanda kama vile mafuta ya petroli, tasnia ya kemikali, na nguvu za umeme.
Ni valve inayotumia operesheni ya kuzunguka kudhibiti mtiririko wa maji. Kawaida huwa na mwili wa valvu, kifuniko cha valve, diski ya valve, shina la valve, na kifaa cha uendeshaji. Aina hii ya valve inafanikisha mtiririko wa kati kufungua au kufunga kwa kuzungusha diski ya valve, na ina utendaji mzuri wa kuziba, ambayo inaweza kuzuia uvujaji wa kati kwa ufanisi.
