Industrial-use Gas Cocks, Valve and Gas Burners

All Our Products Display the JIA Mark-An Internationally Recognized Sign of Japanese Excellence

In the industrial-use gas cock field, Tsuchitani Kinzoku's factory is the first Japan to be permitted to display the JIA mark on its products, and so far we have obtained formal approval to use the mark in conjunction with 22 different items. Our products, which have won a high degree of trust among users, undergo inspections at 35kpa, which is approximately nine times the inspection pressure under the official regulation.

Ever since its establishment, Tsuchitani Kinzoku has conducted development, design, machining, assembly and inspection on an in-house basis and during that time we have developed a long list of successful products.

In particular, we have established an overall system for gas cock production. Furthermore, we will continue to tackle manufacturing with a sincere attitude in the future too.
