Bokosi losinthira la valve ndi chida chakumunda chopangira ma valve odziwikiratu ndi mayankho amawu. Amagwiritsidwa ntchito kuti azindikire ndikuyang'anira momwe pisitoni imayendera mkati mwa valavu ya silinda kapena makina ena a silinda. Ili ndi mawonekedwe a mawonekedwe ophatikizika, mtundu wodalirika komanso magwiridwe antchito okhazikika, ndipo amagwiritsidwa ntchito kwambiri.
Bokosi losinthira valavu, lomwe limadziwikanso kuti zisonyezo za mawonekedwe a valavu, chizindikiro chowunikira, chida chosinthira ma valve, chosinthira cha valve, chimatha kukhazikitsidwa pamavavu osinthira monga valavu, valavu ya diaphragm, valavu yagulugufe, ndi zina zambiri, kuti mutulutse mawonekedwe a valavu ngati chizindikiro chosinthira, chomwe chingakhale.
Kafukufuku pazida zoyankha mavavu m'maiko osiyanasiyana ndizofanana, koma pali kusiyana kwina pamtundu wazinthu ndi mtengo. Zipangizo zowonetsera ma valve nthawi zambiri zimatha kugawidwa m'magulu olumikizana komanso osalumikizana. Zida zambiri zolumikizirana zimapangidwa ndi masiwichi amakina ocheperako. Chifukwa cha kukhalapo kwa magawo olumikizana ndi makina, ndikosavuta kupanga zopsereza. Choncho, pogwiritsira ntchito zochitika zosaphulika, m'pofunika kukhazikitsa chotchinga chosaphulika, chomwe chimakhala chovuta kwambiri. Ngati valavu imayenda pafupipafupi, kulondola ndi moyo wa chipangizo cha ndemanga zidzachepa. Chipangizo choyankhira chosalumikizana nthawi zambiri chimatengera kusintha kwapafupi kwa NAMUR. Ngakhale kuti imagonjetsa zolakwika za chipangizo choyankhira, chiyenera kugwiritsidwa ntchito ndi chotchinga chachitetezo pazochitika zosaphulika, ndipo mtengo wake ndi wokwera.
