ZJH Fa'asologa Pneumatic Diaphragm Pulea Polo Valve

Fa'amatalaga Puupuu:

Pneumatic diaphragm control valve

e aofia ai le tele o le spring zero adjustable actuator, o se lima e tete'e ai le tafe maualalo ma se valve faatonutonu nofoa e tasi e aunoa ma se ufiufi pito i lalo.Ole malosi ole tafe e fa'atupula'ia ile 1/3.E maualalo le ogatotonu o le kalave, maualuga le tete'e ma faigofie ona fa'apipi'i.O fa'asologa o fa'atinoga e sili atu nai lo oloa o le ituaiga tutusa.O oloa o loʻo faʻaaogaina lautele i faiga faʻatautaia otometi i totonu o alamanuia e aofia ai kemisi, suauu, alamanuia mama, nofoaga eletise, ma metallurgy. O le a matou taumafai i le mea sili matou te mafaia e tuʻuina atu ai le valve faʻatonutonu pneumatic maualuga maualuga ma maualuga mo lau poloketi eseese mo le puleaina o le tafe. Su'esu'e i matou e maua le vaifofo free valve!

Fa'amanuiaga ole Valve Pulea ole Pneumatic:

COVNAValves Pulea Pneumatice talafeagai mo le faatonutonuina o le tafe o paipa.O le pa'u fa'amalo e fa'amalosia e le ea fa'apipi'i, e aunoa ma le eletise, saogalemu ma fa'amaonia le pa.E maua ma faʻaalia e le tagata faʻatonu le faailo faʻatonutonu o le faʻaogaina o masini faʻapisinisi e faʻamaeʻa ai le fetuunaiga o le tafe ma le mamafa o le paipa.Fa'aaoga lautele i le fau o va'a, fale eletise, mea'ai ma meainu, ma isi.

Vaega o le ZJH Series Pneumatic Diaphragm Control Valve:

●Globe valve o loʻo faʻauluina e le pneumatic control lea e mafai ai ona faʻafaigofie lau masini ma fesoasoani i lau faʻatonutonuina o le ala sili atu ona saʻo.

●E maua ile ituaiga nofoa tasi ma le ituaiga lima mo lau filifiliga
