Chosefera cha SRFA chimapangidwa ndi zotsekera mbale ziwiri, 2-position 3 -way directioal valve, by-pass valve, indicator ndi diffuser. Ndi yosavuta kapangidwe ndi yosavuta kugwiritsa ntchito. Amakhala pamwamba pa thanki; pali valavu yodutsa ndi chiwonetsero cha kuipitsidwa mmenemo, poteteza ma hydraulic system chitetezo. Mbali ya fyuluta iyi imalola kugwira ntchito mosalekeza ngakhale m'malo mwa chinthu chomwe chimadzazidwa ndi zoopsa. Fyuluta itadzazidwa ndi zoipitsa zomwe zimapangitsa kukakamizidwa kufikira 0.35MPa chizindikirocho chimapereka ma siginolo. Pakadali pano, tembenuzirani njira yolumikizira valavu kuti mupange zojambulazo kenako ndikusintha chinthucho.
