• Kusindikiza mpheteGwiritsani ntchito ma elastomer ochita bwino kwambiri monga EPDM yogwirizana ndi FDA, NBR, PTFE, kapena Viton®,kupereka brKugwirizana kwa mankhwala a oader (mwachitsanzo, kugonjetsedwa ndi mafuta, zidulo, kapena zosungunulira) ndi kutentha kwapamwamba (-20°C mpaka 150°C / -4°F mpaka 302°F).
• Shaft: Chopangidwa ndi chitsulo chosapanga dzimbiri (SS410/316) chokhala ndi malo opukutidwa kapena okutidwa (mwachitsanzo, plating ya nickel) kuti zisawonongeke komanso kutayikira.

1. Kapangidwe Kapangidwe & Kupanga

Ma Valves Otsika

• Mapangidwe Osavuta: Zomanga zokhazikika kapena zokhazikika zokhala ndi zosindikiza zochepa. Diski ndi mpando ukhoza kukhala ndi makina ovuta, zomwe zimatsogolera kugwedezeka kwakukulu ndi torque.
• Msonkhano: Nthawi zambiri amapangidwa mochuluka ndi kuwongolera kocheperako, zomwe zimapangitsa kulekerera kosagwirizana. Miyezo yotayikira imatha kulephera kukwaniritsa miyezo yokhazikika (mwachitsanzo, kupitilira ANSI B16.104 Zofunikira za Gulu la VI).
• Zochitika:Amaphatikizidwa ndi zogwirira ntchito zotsika mtengo kapena zoyatsira magetsi, zomwe sizikhala zolimba kuti zizigwira ntchito pafupipafupi.

• Mapangidwe Apamwamba: Mbalizomanga ziwiri-eccentric kapena patatu-eccentrickuchepetsa mikangano, kupititsa patsogolo kusindikiza, ndi kuchepetsa kuvala. Mwachitsanzo, mapangidwe awiri-eccentric amapanga "wedding effect" kuti atseke kwambiri.
• Precision Manufacturing: Wopangidwa ndi zida zolondola kwambiri za CNC, kuwonetsetsa kuyenda kosalala kwa chimbale ndi kulumikizana koyenera. Miyezo yotayikira nthawi zambiri imakumana kapena kupitilira ISO 15848-1 (mwachitsanzo, Gulu A lolimba ndi Bubble).
• Zochitika: Imagwirizana ndi ma premium actuators (mapneumatic, hydraulic, kapena anzeru magetsi actuators) pamakina othamanga kwambiri, othamanga kwambiri. Zitsanzo zina zimakhala ndi zoikamo malo kapena zomverera zodzipangira zokha.

3. Kuchita & Kudalirika

Ma Valves Otsika

• Zochepetsa Kupanikizika/Kutentha: Oyenera machitidwe otsika kwambiri (mwachitsanzo, ≤PN10 / Kalasi 125) ndi kutentha kochepa. Itha kulephera m'malo opanikizika kwambiri (mwachitsanzo,>PN16) kapena kutentha kwambiri (-10°C mpaka 90°C).
• Moyo Wautumiki: Kufupikitsidwa chifukwa cha kusakhazikika kwazinthu komanso zolakwika zamapangidwe, zomwe zimafunikira kukonzedwa pafupipafupi kapena kusinthidwa (mwachitsanzo, mizungu 10,000–20,000).
• Chiwopsezo cha Leakage: Mwayi wokulirapo wopindika chisindikizo kapena dzimbiri la shaft, zomwe zimapangitsa kutayikira kwachilengedwe kapena kulephera kwadongosolo.

Ma valve a Mid-High-End

• Zochepetsa Kupanikizika/Kutentha: Zopangidwira machitidwe apakati-mpaka-pamwamba (mwachitsanzo, PN16-PN40 / Kalasi 150-Kalasi 300) ndi kutentha kwakukulu (-30 ° C mpaka 200 ° C / -22 ° F mpaka 392 ° F).
• Moyo Wautumiki: Wopangidwira kudalirika kwanthawi yayitali, wokhala ndi moyo wozungulira wopitilira 100,000. Mitundu ina yapamwamba imapereka zitsimikizo zamoyo wonse.
• Kuwongolera kwa Leakage: Zisindikizo zapamwamba komanso ma shaft odana ndi kuphulika amachepetsa kuwopsa kwa kutayikira, kuwapangitsa kukhala oyenera kugwiritsa ntchito zovuta monga makina a gasi kapena kuwongolera madzi owopsa.

4. Mapulogalamu

Ma Valves Otsika

• Zoyenera: Ntchito zosafunikira, zokhala pachiwopsezo chochepa zokhala ndi zofunikira zowongolera kuyenda, monga:
• Njira zoperekera madzi m'nyumba
• Njira yosavuta ya HVAC
• Kuthirira kocheperako kapena ngalande
• Pewani Kugwiritsa Ntchito: Mapaipi akumafakitale opanikizika kwambiri, ma TV owononga, kapena malo omwe ali ndi chitetezo (monga mafuta & gasi, mankhwala).

Ma valve a Mid-High-End

• Zoyenera Kwa: Kufuna ntchito zamafakitale ndi zamalonda, kuphatikiza:
• Makina opangira ma Chemical (zamadzimadzi owononga)
• Kupanga zakudya ndi zakumwa (zaukhondo)
• Kupanga mphamvu (nthunzi yotentha kwambiri)
• Mafuta ndi gasi (zofunika kuti zisamaphulike)
• Mfundo Zofunika Kwambiri: Nthawi zambiri zimatsimikiziridwa ndi ISO, API, ASME, kapena ATEX kuti zitsatire malamulo achitetezo apadziko lonse lapansi.

5. Mtengo & Kusamalira

Ma Valves Otsika

• Mtengo Woyamba: Zotsika mtengo kwambiri (20-50% zocheperapo kusiyana ndi zitsanzo zapakati), zomwe zimawapangitsa kukhala okondweretsa ma projekiti okhudzidwa ndi bajeti.
• Kusamalira: Kukwera mtengo kwanthawi yayitali chifukwa chakusintha zisindikizo pafupipafupi, kuthira shaft, kapena kukonza dzimbiri.
• Chiwopsezo cha Downtime: Zambiri zomwe zimakhala zolephera zosayembekezereka, zomwe zimapangitsa kuti pakhale kuwonongeka kwa mafakitale.

Kusankha Vavu Yoyenera (mwachitsanzo.Chithunzi cha TWS)

• Mapeto Otsika: Ndioyenera kugwiritsidwa ntchito kwakanthawi kochepa, kosafunikira komwe mtengo ndiye chinthu chofunikira kwambiri.
• Mid-High-End: Ikani mu izi kuti mukhale odalirika, otetezeka, ndikugwira ntchito kwanthawi yayitali pamapulogalamu ovuta. Nthawi zonse ganizirani za mtundu wa media, momwe mungagwiritsire ntchito, komanso zofunikira pakutsata posankha vavu.
