Valve & Piping Systems

01A pioneer in the manufacture of plastic valves


It was in 1956 that ASAHI YUKIZAI pioneered the manufacture of plastic valves. There were only metal valves in those days, and sites that handled chemicals or seawater had no option but to frequently replace valves due to corrosion and rusting. That is what inspired us, as a company that dealt in plastics, to develop our vinyl chloride valves, Nowadays many manufacturers sell plastic valves, but our strength is that no other company can match the technical know-how we have amassed over many years or our extensive product lineup.

02Plastic valves are used in such places as steel mills, chemical plants, semiconductor factories, agricultural irrigation systems and aquariums

ASAHI YUKIZAI started manufacturing plastic valves in 1956. Ever since then they have been in wide use by our customers because they are indispensable on the factory floor at steel mills, chemical plants, semiconductor factories, and other such sites. They are in use not only in factories, but also, for example, in water and sewage systems, agricultural irrigation systems, and in systems to control water circulation in aquariums and fish farms. Armed with our wealth of experience and technological capabilities, we will continue to provide products and solutions that can improve our daily lives in many ways.

03Developing and delivering optimal solutions for each customer

The advantages of plastic valves are that they are light, do not rust, and have a long operating life. That is why they are so reliable, and why they stand up so well to fluids other than fresh water, such as chemicals and seawater. As the company that pioneered plastic valves, we have confidence in the strong appeal of our products. What we want now is to resolve the various issues faced by our customers. We are proud to say that our greatest value is the combined capabilities that enable us to develop and deliver optimal solutions for each customer, thanks to our thorough knowledge of pipe materials and stance of working closely with our customers.

04We manufacture and market plastic valves, and can offer one-stop solutions to your issues

We manufacture and market plastic valves and other flow control products such as pipes and joints. Over the course of more than 60 years, we have amassed a wealth of experience and big data with regard to plastics. From that position of strength, we are developing maintenance services such as ultrasound tests and UV damage checks for valves and pipes, and engineering services that offer total solutions covering everything from pipe design to installation. Recently, we are also engaged in the manufacture and marketing of high-purity fluororesin valves that contribute to semiconductor advancements. We offer these products to provide solutions to your issues.
