“Kong Hsin Enterprise” was established as a valve manufacturer for Taiwan market in 1974. In 1977, Kong Hsin Enterprise increased its capital and registered as “Kong Sheng Valve Industrial Co., Ltd”(KSV). With years of new product development and quality consistence, the reputation of “KSV made” was heard in the international market. It was a starting point for KJV when oversea orders were received. Therefore, “Kong Jih Valve Industrial Co., Ltd” (KJV Plant#1) was established in 1990 and Plant#2 was established in 2009 to handle export business for OEM/ODM products. In 2013, we’ve also complete the supply chain integration by establishing the lost-wax casting foundry for investment castings.

KJV has more than four decades in manufacturing, from a small machining shop in Shilin, Taipei City and Danshui, New Taipei City residential area to precision CNC machine, efficiency assembly conveyor lines, temperature & humidity control warehouse and modern office building in Dajia, Taichung City. We appreciate the support from our dedicated employees, loyal customers, and value suppliers. KJV has created a harmonious and joyful working atmosphere between KJV and interested parties. KJV is full of experienced employees, customer trusts, and reliable supplier chains. In our belief, it is a right business culture to acquire the maximum balance point among interested parties.
Thank you for visiting the KJV website. You are more than welcome to join us. KJV is expecting to share the thriving experience with you.

1974年設立閥門公司”功興企業社”,以生產銷售台灣市場為主。1977年,公司擴張資產,以”功勝凡而”之名向政府申請營業登記。 經過幾年成功的產品開發和對品質的堅持,”功勝製造”的名聲在市場上被聽見,國外客人開始下單,而這正是功勝的轉捩點。在1983年取得第一個國外客戶的訂單,銷售市場從台灣邁向國際,並於1990年設立”功億工業股份有限公司”、2009年設立功億二廠,專以出口閥門業務為主,並於2013年設立鑄造廠以垂直整合閥門供應鏈。

I was a lab researcher before joining KJV. Experiments were common tasks for me back then. Correct chemicals, procedures, key variables, records, and safety are important things to a successful experiment. A good laboratory practice deeply affects my leadership and management style. Now, manufacturing procedures, detailed records of each steps, occupation safety, and health are critical elements to produce high quality and consistent products.
I have worked in KJV more than 10 years. During the time, I have learned International specifications and certifications for valve industry. In addition, I am familiar with manufacturing process in order to improve the KJV quality system. Therefore, recognition has been won by several external and customer audits. KJV is listed as a preferred manufacturer in several world-renowned oil and gas industries.
Recently, KJV determines its target and policy by introducing the SWOT analysis model. KJV is able to project its growth and reduce its risks to achieve its goal.

C.S. Chen

Our valuable employee

I started at Production management section and retired at Quality management section. After retired, I was honor to be hired as one of Quality committee members. So far, I work in KJV almost 20 years. For the purpose of improving the company quality system, I am lucky to have outside training opportunities in order to assist company to receive International Certifications’ approval and pass customer audits in the preferred manufacturer list. I really appreciate the opportunities provided by the company. In addition, I am full of working vitality by seeing the progresses of company and myself.

By Quality Committee Member, Mrs. Wen

I work in an assembly line 20 years. In the past, I considered the assembly as boring tasks because it does routine tasks over and over. However, when I actually assemble products after understanding assembly procedure and design concept from senior staffs, I understand that our products are installed in critical environments and assembly is an important task. In addition, 5S (sort, set in order, shine, standardize, sustain) management and new product developments have bring in a variety of tasks in a comfortable working environment. Besides learning working knowledge, I am also happy to work here because of the warmness from colleagues.

Assembly line, Mr. Chang
