Leadership
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.

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, then promoted to Quality Department Manager.
So far, I’ve been working in KJV for almost 40 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 Department Manager, Mrs. Wen
I have been working on the assembly line for 20 years. Through learning by doing, I came to understand the importance of every step in the process. Our products are installed and operated in critical environments, making the quality and precision of each assembly task essential to overall product reliability and performance.
As I gained experience over the years, I was honored to be promoted to Section Chief. This opportunity allowed me not only to deepen my understanding of assembly operations, but also to develop leadership and management skills, including team coordination and employee development.
Looking back on the past 20 years, I am proud to have grown alongside the company and to continue learning through every challenge and opportunity.
Assembly line, Mr. Wu
