Our major products are cast and forged steel valves with a wide variety of low volume production and mass-produced small forged valves. We have established manufacturing methods for cast and forged steel valves based on the accumulation of proprietary technologies since our foundation. We have developed a strong reputation with our technologies in many different fields today. We have been providing many different types of valves while always considering “what kinds of valves are necessary for our customers” and “will they be satisfied with them.” All parts are made in Japan, and we strive for reliable manufacturing based on our intimate communication system from order reception through to after-sales service.
