Kubathengi, kubaluleke kakhulu ukukhetha okuhleukuvalwa kwe-valve, ngakho-ke khetha ngokucophelela futhi uqhathanise abakhiqizi abaningana.

Umhleli ongezansi ukutshela amathiphu okukhetha ukuvala ama-valve

1. Uma ubheka izindinganiso zokuhlola, izingidi zehadiwe emhlabeni wonke zinezincazelo eziqine kakhulu.Ukuze wonge kangcono izindleko, abakhiqizi abancane abalandeli imininingwane, futhi amabhrendi amakhulu ngokuvamile alandela izicaciso.

2. Kufanele ukhethe umkhiqizo omkhulu noma i-ejenti yomkhiqizo enegama eliphezulu nomlando omude wokujoyina.Ngenxa yokuthi banamandla anele ezomnotho kanye nesistimu yohlelo lokusebenza oluzinzile ukuze baqinisekise izinto zesevisi kanye nezinsizakalo zokulungisa ngemva kokuthengisa, bangavimbela izingxabano ezibangelwa izinkinga zekhwalithi yomkhiqizo.

3. Ama-valve ahlukaniswe ama-valve esango, ama-butterfly valves, ama-globe valves, ama-rotary valve, njll. Ngakho-ke, izinhlobo ezidingekayo zama-valve kufanele futhi zisungulwe lapho kukhethwa ukuvala ama-valve.

4. Ukuvala ama-valve kungakhetha izinto ezihlukahlukene, ngokusho kwendawo yemvelo yesicelo sokukhiya, njengokoma kwegesi, kungakhathaliseki ukuthi izinga lokushisa eliphezulu, kungakhathaliseki ukuthi kufanele limelane nokugqwala, futhi ukhethe ukukhiya okufanele.

5. Ukucaciswa kwe-valve, ngokusho kwemininingwane ehlukene ye-valve, khetha okufanelei-valve yokuvala.

6. Hlola ukuthi izimpawu nezimpawu zokupakisha zokuvala i-valve ziphelele yini (okuhlanganisa izinga likazwelonke lomkhiqizo, izinga, igama lomkhiqizi, ikheli elinemininingwane, nosuku lokukhiqizwa) ukuthi impahla yokukhiqiza iqinile, nokuthi okuqukethwe yimiyalelo yokusetshenziswa kuyahambisana nomkhiqizo, futhi kuvimbele ngokuqinile ihaba futhi amaqiniso anenjongo awahambelani.
