Raws li cov tub ntxhais valve, daim duab peb sab valve tuaj yeem muab faib ua kheej kheej valve core, ceramic valve core, ABS (engineering yas) valve core, alloy valve core, thiab roj hmab teb valve core. Spherical spool: Qhov kom zoo dua ntawm lub spherical spool yog txoj kab uas hla loj dua li ntawm cov spool ceramic, nws yuav tsis txo cov dej siab thiab ntws, thiab nws yooj yim rau kev khiav lag luam (tag nrho qhib / kaw los ntawm rotating 90 degrees). STH spool yog chrome-plated. Qhov zoo ntawm chrome plating yog siab hardness, hnav tsis kam thiab ua haujlwm ntev; zam patina. ABS (engineering yas): Cov yas valve core yog tus nqi qis, thiab qhov zoo tsis tau lees paub. Ceramic valve core: Qhov kom zoo dua ntawm ceramic valve core yog tias qhov hloov tau zoo li du thiab lub teeb. Nws yog tsim rau cov tsev neeg, muaj lub neej ua haujlwm ntev thiab tus nqi siab. Ceramic spools raug pom zoo. Rubber rotary valve core: Tam sim no nws tau raug tshem tawm vim nws siv sijhawm ntev heev thiab siv zog los qhib thiab kaw. Tam sim no, tsev neeg tsis tshua siv lub kaum sab xis ntawm cov khoom siv no. Daim duab peb sab valve tau muab faib ua tooj dag, alloy, hlau thiab yas raws li cov khoom siv plhaub. Brass: yooj yim rau txheej txheem, muaj zog plasticity, hardness, thiab muaj zog dabtsi yog khoov thiab torsion kuj. Alloy: tus nqi qis, qhov tsis zoo yog qhov qis qis thiab torsion tsis kam, thiab qhov saum npoo yooj yim rau oxidize. Hlau: yooj yim rau xeb thiab paug dej. Nws tsis pom zoo kom siv nyob rau niaj hnub no ib puag ncig-phooj ywg thiab cov pa roj carbon tsawg. Yas: tus nqi qis, tsis haum rau siv nyob rau sab qaum teb txias heev.
