He kaiwhakarato motuhake matou ki te tuku i te Huade® pressure reduction valve DR 20. Ko Huade Hydraulic he hinonga matua o te motu i Haina. He hinonga nui a te kawanatanga e tohunga ana ki te hoahoa, te hanga me te ratonga. Ko ona hua ka kaweake ki te ao katoa. Na roto i nga whakawhitinga mahi hangarau e rua mo te wa roa me Rexroth, he hototahi nga reera waipulu Huade® ki a Rexroth i te mahi. I runga i nga korero, he iti noa te utu.
Momo DR 20 ka whakamahia te paera whakaheke pehanga hei whakahaere i te pehanga. Na roto i te whakauru i te hangarau matatau a Rexroth me nga taputapu whakangao tino matatau mai i nga wa katoa o te ao, he pai te kounga me te utu iti o Huade® te pehanga whakaheke i nga waahana. Ko Huade he tohu mo te motu Hainamana rongonui, a ko ana hua e whakamahia nuitia ana i roto i nga mara maha penei i te miihini miihini, te tiaki wai, nga taputapu miihini, te hinu me nga matū, aha atu.

Wāhanga me te tohu o te Pressure Reducing Valve DR 20
Ko nga momo DR 20 nga momo pehanga pehanga he maataki whakaheke pehanga, he mea whakahaere mai i te ara iahiko tuarua. Ko te tikanga ko te takirere matua (1) me te whakauru pokai matua(3) me te takirere pairati (2) me te huānga whakatikatika pehanga.
I te okiokinga, ka tuwhera nga marere, ka rere noa te wai mai i te tauranga B ki te tauranga A ma te whakauru o te kopapa matua (3).
Ko te pehanga kei roto i te tauranga A ka mahi ki te taha o raro o te porowhita matua. I taua wa ano he pehanga kei runga i te poi(6) i roto i te takirere pairati (2) ma te kohao (4) i te taha puna kua utaina o te piston matua (3) me te tauranga(5). He rite tonu te mahi i runga i te poi (6) ma te puha (7), te raina whakahaere (8), te taki taki (9) me te puha (10). E ai ki te whakatakotoranga o te puna(11), ka piki te pehanga ki mua o te poi (6), ki te tauranga (5) me te ruma puna(12), ka mau te piston mana (13) i roto i te
tūnga tuwhera. Ka rere noa te wai mai i te tauranga B ki te tauranga A ma te whakauru porowhita matua (3), kia neke ake te pehanga o te tauranga A i te uara kua whakaritea i te puna (11) ka whakatuwhera i te poi (6).
ka neke te piston (13) ki te waahi kati.
Ka tutuki te pehanga whakaheke e hiahiatia ana, ina tae te taurite i waenga i te pehanga i te tauranga A me te pehanga kua whakaritea i te puna (11). Ko te rere o te hinu pairati mai i te ruuma puna(14) ki te tank ka puta ki waho ma te raina mana (15).
Ka taea te hokinga kore utu mai i te tauranga A ki te B ma te whakauru i tetahi taki taki (16).
Ma te hononga ine pehanga (17) ka taea te aro turuki i te pehanga whakaheke i te tauranga A.
te hanganga o te momo whakapuru pereti DR 20...50B
