We conduct joint research with major companies on safety valves for rockets and maglev trains.

Our company designs and manufactures safety valves for low-temperature gas, steam, gas, liquid, and blow molding machines. We also handle pressure-regulating and safety valves for pure steam, and vacuum safety valves including articles for nuclear equipment. In terms of quality control we have been certified by the Minister of Economy, Trade and Industry as a manufacturer that conducts tests on high pressure gas equipment. We hold Japanese Utility Model Registration No. S34-53752 for a quick-opening valve using a differential pressure-regulating valve. We received a commendation for safety from the Shinagawa Labor Standards Inspection Office in 2002. We conduct joint research with Mitsubishi Heavy Industries, Ltd. for safety valves for rocket fuel, and with Hitachi, Ltd. for maglev trains.
