Balbula ng gate ng NRS na may matibay na pagkakaupo na may seryeng EZ
Paglalarawan:
Ang EZ Series Resilient seated NRS gate valve ay isang wedge gate valve at Non-rising stem type, at angkop gamitin sa tubig at mga neutral na likido (dumihan).
Katangian:
-Online na pagpapalit ng pang-itaas na selyo: Madaling pag-install at pagpapanatili.
-Integral na disc na may takip na goma: Ang ductile iron frame work ay thermal-clad na may integral na high-performance na goma. Tinitiyak nito ang mahigpit na selyo at pag-iwas sa kalawang.
-Pinagsamang tansong nut: Sa pamamagitan ng espesyal na proseso ng paghulma, ang tansong tangkay ng nut ay isinama sa disc na may ligtas na koneksyon, kaya ang mga produkto ay ligtas at maaasahan.
-Uupuang may patag na ilalim: Ang sealing surface ng katawan ay patag at walang guwang, kaya't naiiwasan ang anumang dumi.
-Whollly-through flow channel: ang buong flow channel ay dumadaan, na nagbibigay ng "Zero" na pagkawala ng presyon.
-Maaasahang pagbubuklod sa itaas: dahil sa istrukturang multi-O ring na ginamit, maaasahan ang pagbubuklod.
-Patong na epoxy resin: ang hulmahan ay iniispreyan ng patong na epoxy resin sa loob at labas, at ang mga hulmahan ay ganap na nababalutan ng goma alinsunod sa mga kinakailangan sa kalinisan ng pagkain, kaya ito ay ligtas at lumalaban sa kalawang.
Aplikasyon:
Sistema ng suplay ng tubig, paggamot ng tubig, pagtatapon ng dumi sa alkantarilya, pagproseso ng pagkain, sistema ng proteksyon sa sunog, natural na gas, sistema ng liquefied gas, atbp.
