■Company Outline

Under the company slogan, “Joining water with life,” MAEDA VALVE CO., LTD. is committed to the development of the water supply business by manufacturing “valves” and “fittings to connect distribution pipes” with excellent multiproduct production technology, advanced product development, and the best possible quality control measures.

■Main Products


Even though water supply devices have a relatively low profile, they are used as key components of water supply systems and work in the background for the benefit of people's lives.
MAEDA VALVE is an integrated manufacturer of products for water works, such as corporation stops with saddle clamp to connect a distribution pipe to a water pipeline supplying water for home use, stop valves for opening and shutting the water to households, and fittings to connect distribution pipes.

■Core Competence

MAEDA VALVE accepts orders for even one item that must meet the specifications of the water supply system established by each of the local municipalities nationwide.
From Hokkaido to Okinawa, public water supply agencies use proprietary water supply systems. Since the start of operations, we have been designing, developing, and improving our production lines. Recently, we built a unique casting production line in a plant located near Nagoya Port. This system enables us to stably produce more models in smaller quantities and embrace a wider marketing strategy. We are capable of responding to orders with different specifications and providing services throughout Japan. Many water supply agencies use our products to distribute water to individuals.
