E masani ona fa'aaogaina ASCO pulse valves i faiga e aoina ai le pefu. O pusa diaphragm e fa'aaogaina e sui ai le diaphragm pe a fa'aleagaina i totonu o nei pulse valves. O nei pusa e masani ona i ai diaphragms, springs, ma isi vaega e mana'omia mo le valve ina ia galue lelei. Se'i fa'aaoga le 3.5 inisi pulse valve SCR353G235 o se fa'ata'ita'iga, matou te gaosia ma sapalaiina pusa diaphragm 3.5 inisi mo 3.5 inisi asco pulse valves. O lo'o fa'aalia i lalo le ata, fa'amolemole silasila i pusa diaphragm ASCO 3 1/2"

A e fa'atau se pusa o le diaphragm, ia mautinoa e te fa'atau le pusa sa'o mo lau fa'ata'ita'iga patino o le pulse valve. E mafai ona e fa'afeso'ota'i matou a'o le'i fa'atauina.
