持續(xù)改進(jìn)，追求零缺陷”是凱斯通閥門永不懈怠的質(zhì)量方針和目標(biāo)。
"Continuous improvement, the pursuit of zero defect" is Kestong valve never slack quality guidelines and goals.

我們以高于國(guó)際、國(guó)內(nèi)標(biāo)準(zhǔn)及客戶要求，建立內(nèi)部的質(zhì)量保證體系，實(shí)施全面、全程質(zhì)量管理。凱斯通閥門擁有先進(jìn)的檢測(cè)中心，能夠自主獨(dú)立完成從產(chǎn)品原型試驗(yàn)認(rèn)證到產(chǎn)品出廠檢驗(yàn)全部的檢驗(yàn)、檢測(cè)；這些檢驗(yàn)、檢查包括：射線探傷、著色探傷、磁粉探傷、超聲波探傷、光譜分析、材料鑒別（PMI）、金相組織檢測(cè)、各種機(jī)械性能試驗(yàn)、防火試驗(yàn)、超低溫試驗(yàn)、高溫試驗(yàn)、真空試驗(yàn)、低泄漏試驗(yàn)、高壓氣體試驗(yàn)、流體動(dòng)力試驗(yàn)、產(chǎn)品壽命試驗(yàn)，以及常規(guī)水壓等一系列閥門實(shí)驗(yàn)。
We are higher than the international and domestic standards and customer requirements, the establishment of an internal quality assurance system, the implementation of a comprehensive, full quality management. 
Kestong valve has advanced testing center, independently from the product prototype test certification to the final product inspection of the entire factory inspection, testing; these tests, inspection include: ray inspection, color inspection, magnetic detection, 
ultrasonic testing, spectral analysis , Material identification (PMI), metallographic examination, various mechanical properties tests, fire tests, cryogenic tests, high temperature tests, vacuum tests, low leakage tests, 
high pressure gas tests, hydrodynamic tests, product life tests, A series of valve experiments.

為確保毛坯質(zhì)量凱斯通閥門設(shè)有自己的鑄件工廠，從原料生產(chǎn)到成品出庫(kù)有效管控每一過(guò)程。此外，凱斯通閥門積極實(shí)施六西格瑪管理，在公司內(nèi)部推行 “零缺陷”項(xiàng)目，并通過(guò)先進(jìn)的數(shù)據(jù)統(tǒng)計(jì)分析，達(dá)到持續(xù)提高過(guò)程控制與管理能力。
In order to ensure the quality of the rough Castel have their own casting plant valves, from raw material production to the finished product out of the library effectively control each process. 
In addition, Catone Valve actively implements Six Sigma management and implements "Zero Defects" within the company. 
Through advanced data statistics and analysis, it continuously improves the ability of process control and management.
