Motoyama Eng. Works | Industrial Control & Safety Valves

Motoyama control valves are engineered to regulate fluid flow, pressure, and direction across demanding industrial process systems. The product range includes globe, angle, butterfly, eccentric rotary, three-way, and special-application valves, together with pneumatic and electric actuators and valve positioners.  Depending on the operating conditions, configurations can be selected for high-temperature and high-pressure service, low-noise operation, cavitation or flashing conditions, viscous fluids, slurry applications, and environments requiring enhanced resistance to corrosion or erosion.  Motoyama safety valves are designed to protect process equipment and piping against excessive pressure. Available configurations include conventional, balanced-bellows, pilot-operated, steam-service, large-size, and compact safety valve designs.  Valve selection is determined according to the operating fluid, pressure, temperature, required flow capacity, body and trim materials, connection standard, actuator configuration, and applicable project or regulatory requirements. Nichiboku supports international customers with model identification, technical specification coordination, documentation, and export supply for replacement and new-project applications.
