ʻO ka valve solenoid proportional he ʻano kūikawā o ka valve solenoid e hāʻawi maʻalahi

a me nā loli mau i ke kahe a i ʻole ke kaomi ma muli o ka hoʻokomo uila. Hiki i kēia ʻano

e hoʻokaʻawale ʻia e like me ka valve control. I mea e like ai ka solenoid valve, ka plunger

pono e hoomaluia ke kulana. Loaʻa ia ma ke kaulike ʻana i ka plunger me ka ikaika o waho

hana mau ʻia e kahi pūnāwai. E kaomi ka puna a hiki i ka like ana o ka ikaika o waho me ka electromagnetic

ikaika o ka solenoid. Inā pono e hoʻomalu ʻia ke kūlana o ka plunger, pono e hoʻololi ʻia ke ʻano,

ka hopena i ke kaulike ʻole o nā mana ma ka pūnāwai. E hoʻopaʻa a kikoo paha ka pūnāwai a hiki i ka ikaika

bUa hoʻokumu ʻia ʻo alance.

             ʻO kekahi pilikia me kēia ʻano ka hopena o ka friction. Hoʻopilikia ka friction i ke kaulike maʻemaʻe

ma waena o nā mana electromagnetic a me nā pūnāwai. No ka hoʻopauʻana i kēia hopena, nā mana uila kūikawā

hoʻohana ʻia. ʻO kahi ʻano hana maʻamau i hoʻohana ʻia no nā hiʻohiʻona hoʻokele proportional o nā valve solenoid

ʻO ka hoʻololi ʻana i ka laulā pulse a i ʻole PWM. Ke noi ʻana i kahi hōʻailona PWM ma ke ʻano o ka hoʻokomo ʻana i ka solenoid

i ka mana a me ka hoopau mau i ka wikiwiki loa. Hoʻokomo kēia i ka plunger i kahi kūlana oscillating a

pela i ke kulana kupaa. E hoʻololi i ke kūlana o ka plunger. ʻO ke kūlana a me waho o ka solenoid,

ʻike ʻia hoʻi ʻo ka pōʻai hana, ua hoʻomalu ʻia.

              ʻAʻole e like me nā valve solenoid maʻamau, hoʻohana ʻia nā valve solenoid proportional i nā noi

e koi ai i ka mana kahe otometi, e like me ka proportional pneumatic actuators, throttle valves, burner

mana, etc.
