I-valve yokulawula ejwayelekile iqukethe umzimba we-valve, izingxenye zangaphakathi ze-valve, i-actuator ehlinzeka ngedrayivu yokusebenza kwe-valve, kanye nezinhlobonhlobo zezisekeli zamavalvu. Izesekeli zamavalvu zihlanganisa ama-positioners, ama-transducer, izilawuli ze-pressure, ama-solenoid valves, ama-dampers nama-switch switch.

1. Ukukhethwa nokusebenzisa ama-valve okulawula
Ukukhethwa okulungile kwama-valve okulawula kanye nokuthi ukufeza izidingo zokulawula izimo zokusebenza ezicacisiwe zokhiye, kodwa futhi nokuqinisekisa ukuphepha kwenqubo. Ukuze kuhlangatshezwane nezidingo zezimo ezishiwo, ukukhethwa kwama-valve okulawula kudingeka kubhekwe uhlobo lomzimba we-valve, ukwakheka kanye nempahla yezingxenye ze-valve, uhlobo lwe-actuator kanye nesici sokuphepha nezinye izakhi, uhlobo lwevalvu yokulawula ekhethiwe luyinhlanganisela efanele.

2. Izici zokukhetha ama-valve okufanele zicatshangelwe
Ukuze ukhethe i-valve yokulawula efanele izimo, udinga ukucabangela ngokucophelela umthelela wokukhethwa kwe-valve yokulawula izimo ezihlukahlukene zokusebenza. Ulwazi olubaluleke kakhulu oluhlanganisa ukulawulwa kohlobo lwe-fluid, izinga lokushisa loketshezi, i-viscosity yoketshezi, amandla adonsela phansi uketshezi oluthile, umthamo omkhulu kanye nobuncane bokugeleza, ingcindezi ephezulu kanye nencane yokungena kwe-valve, ukucindezela okukhulu nokuncane kokuphuma kwe-valve, ingcindezi ukwehla ngaphansi kwezimo zokugeleza ezijwayelekile, inani labantu kanye nenani lepayipi lokuphuma kanye nokuqina kodonga.

3. Inqubo yokukhetha i-valve yokulawula
Indlela yokukhetha i-valve yokulawula efanele ukuhlangabezana nezidingo zohlelo lokusebenza lwemibandela, inqubo yokukhetha i-valve yokulawula okungenani idinga ukucabangela inqubo elandelayo. Nquma izimo zokusebenza: kufaka phakathi inani le-valve kanye nokuphuma kokucindezela okukhulu kokuhlukana, izimo eziphezulu, ubuncane kanye nezimo ezivamile zokusebenza zezinga lokugeleza, izinga lokushisa loketshezi kanye nomsindo ovumelekile. Bala inani elidingekayo le-C, bese unquma izinga lomsindo, i-cavitation kanye nokucwayiza ngokubala ℃-value). Ukukhethwa kohlobo lwama-valve angaphakathi: Uma inani lomsindo elibaliwe likhulu kunomkhawulo ovunyelwe indawo yokusebenza, kufanele kucatshangelwe ukukhethwa kwabangaphakathi kwamavalvu anciphisa umsindo. Uma i-cavitation ebaliwe noma i-flash value ye-valve emsebenzini ocacisiwe ngaphansi kokusetshenziswa kwesikhathi eside komthelela omkhulu, kufanele kucatshangelwe izimo ezicacisiwe ze-anti-cavitation kanye ne-anti-flash valve components.
