Established in 1927, Hamai continually challenges ourselves to broaden our expertise as a valve manufacturer. With a wide range of products, we make the best use of over 80 years of experience, state of the art manufacturing facilities and a constant pursuit of safety.
With a goal of leaving our environment a better place, Hamai has developed valves for compressed natural gas and hydrogen fuel cell vehicles. These technologies reduce the carbon footprint for a cleaner tomorrow.
