NORTECHis ib qho ntawm cov thawj coj hauv Suav tebGlobe Valve Chaw tsim tshuaj paus & tsum.

Lub kaw-off valve yog hais txog lo lus rooj vag uas lub kaw (wide flap) txav mus rau hauv kab nruab nrab ntawm lub rooj zaum valve.Raws li daim ntawv txav no ntawm lub valve disc, qhov hloov ntawm lub rooj zaum qhov chaw nres nkoj yog proportional rau lub valve stroke.Txij li thaum qhib los yog kaw stroke ntawm lub valve qia ntawm no hom valve yog luv luv,
Ntxiv mus, nws muaj kev txhim khu kev qha heev, thiab vim hais tias qhov kev hloov ntawm lub rooj zaum lub rooj zaum qhov chaw nres nkoj yog proportional rau lub stroke ntawm lub valve disc, nws yog heev haum rau txaus hloov.Yog li ntawd, hom kaw-off valve no zoo heev rau siv los ua lub kaw-off lossis hloov thiab throttling.
Qhov zoo tshaj plaws ntawm lub ntiaj teb valve yog tias nyob rau hauv tus txheej txheem ntawm kev qhib thiab kaw, kev sib txhuam ntawm lub dav flap thiab dav sealing nto yog me dua li ntawm lub qhov rooj valve, yog li nws yog hnav-resistant.Qhov qhib qhov siab yog feem ntau tsuas yog 1/4 ntawm txoj kab uas hla ntawm lub rooj zaum valve, yog li nws tsawg dua li lub rooj vag valve.
Feem ntau tsuas muaj ib qho kev sib khi ntawm lub valve lub cev thiab lub valve disc ntawm qhov nres valve, yog li cov txheej txheem tsim khoom ntawm qhov nres valve yog qhov zoo, thiab qhov nres valve yog yooj yim los tswj.Nominal siab lossis qib siab ntawm lub ntiaj teb valve: PN1.0-16.0MPa, ANSI CLASS150-900, JIS
10-20K, nominal txoj kab uas hla los yog caliber: DN10 ~ 500, NPS1/2-36, nres valve kev twb kev txuas txoj kev: flange, taub qab vuam, xov, thiab lwm yam., siv kub: -1969 ℃ -700 ℃,
Tsav hom: phau ntawv, bevel iav tsav, pneumatic, hluav taws xob, hydraulic, roj-kua linkage, electro-hydraulic linkage,
Broad lub cev cov ntaub ntawv: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mо2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti,
Cov ntaub ntawv sib txawv yog siv rau kev hloov kho, uas tuaj yeem siv rau ntau yam xov xwm xws li dej, chav, roj, nitric acid, acetic acid, oxidizing nruab nrab, urea, thiab lwm yam.
