Basa reiyo pneumatic control valve handwheel yakakura. Iyo handwheel mechanic inoshandiswa pamwe chete nevhavha inoronga, uye mashandisiro makuru ndeaya anotevera:
1 Kana chiratidzo chemhepo kana chiratidzo chemagetsi chikakundikana, kana kana zvikamu zvikuru zve actuator (zvakadai se diaphragm, chitubu, chisimbiso, kutumira, nezvimwewo) zvakakuvadzwa, kushandiswa otomatiki kunofanira kuchinjwa kushanda kwemaoko, uye handwheel inogona kushandiswa. Iyo nzira inoramba ichichengetedza basa rekugadzirisa revhavha inogadzirisa.
2 Iyo handwheel inogona zvakare kushandiswa seyekumisikidza yekudzora vharuvhu sitiroko. (Limit basa)
3 Iyo handwheel mechanism inogona kuvandudza kuvimbika kwekushanda kwevhavha inogadzirisa. Kana bypass yakawedzerwa kune inodzora valve, mari inodiwa.
Mutengo wacho wakakura, nzvimbo yacho yakakura, uye mutengo wacho unokwirisa kana caliber yakakura kana kuti panoshandiswa simbi dzinokosha. Zvinonyanya kudhura-kushandisa vhiri reruoko zvisinei nemutengo wekudyara kana nzvimbo yepasi.
Pamusoro pezvo, kune imwe-mavharuvhu anoita diaphragm, basa uye maitiro ekuita kwevhiri reruoko (kwakananga kwekuita kwevharuvhu) kune kwakananga. Panguva imwecheteyo, diaphragm-mavharuvhu ekuita anowanzo shandiswa munzvimbo idzo dzvinyiriro yemaitiro idiki uye zvinodikanwa zvekuvhara hazvina kuomarara, uye simba racho harina kunyanya kukura. Naizvozvo, zvakakwana kuisa vhiri reruoko zvakananga, pasina chikonzero chekugadzira labor-kuchengetedza mavhiri emaoko emudziyo (kunze kweakakosha), uye hazvigoneke kushandisa mabhaudhi. Mabhaudhi anowanzo shandiswa pa double-acting, piston-type actuators. Iyo kaviri-vharuvhu yokuita handiyo zvayo. Iyo yakafara-yakapetwa kaviri{12}vharuvhu inoita sevhiri remaoko rinokwanisa kuvhurwa nekuvharwa.
