ʻAʻole hiki ke hoʻopōʻino ka hydraulic reversing valve o nā mea kanu asphalt mixing, akā i kekahi manawa hiki ke loli i ka manawa kūpono ʻole, leakage gas, electromagnetic induction pilot valve, a me nā mea ʻē aʻe.

Inā ʻaʻole e hoʻololi ka valve hydraulic reversing i ka manawa, ʻo ia ka hapa nui o ka hopena maikaʻi ʻole, ka puna a i ʻole ka pōʻino, nā ʻili aila a i ʻole ke koena i hoʻopaʻa ʻia i ka ʻāpana huki, etc. Pono e nānā i ke kūlana o ka triplex pneumatic a me ka viscosity o ka momona. Inā pono, hiki ke hoʻololi i ka momona a i ʻole nā ​​ʻāpana ʻē aʻe.
I ka wā lōʻihi o ka hoʻohana ʻana, hiki i ka hydraulic reversing valve o ka asphalt mixing plant ke hoʻopōʻino i ke apo sealing core valve, noho valve a me ka valve kiʻekiʻe-pressure, e hoʻoheheʻe ʻia ke kinoea i loko o ka valve. I kēia manawa, pono e hoʻololi ʻia ke apo hoʻopaʻa, ka noho valve a me ke kīpē ʻīpuka kiʻekiʻe, a i ʻole e hoʻololi ʻia ka valve reversing hydraulic i ka manawa.
No laila, i mea e hōʻemi maikaʻi ai i ka helu hemahema o ka mea kanu asphalt mixing, pono pono e hoʻolohe i ka mālama ʻana i nā mīkini a me nā ʻāpana.
