Advantages of using Tokai Spring Industries’ products

High performance springs that function accurately at the set pressure

Tokai Spring Industries manufactures custom-made valve springs for manufacturers of safety valves for power plants (important valves for electric power) in Japan and overseas. We manufacture not only springs that meet the various Japanese safety valve standards, but also springs that control the lateral load generated in the spring, which affects the valve function. With our half-century of experience in supplying springs for safety valves and our spring manufacturing technology cultivated to meet the world’s strictest quality requirements for safety valves in Japan, we will surely solve the problems of safety valve manufacturers. Please contact Tokai Spring if you have any problems with safety valves.
