Steel Castings

OKANO VALVE manufactures high pressure and high temperature valves for nuclear power plants and thermal power plants.
From 1943,OKANO VALVE has been developing and manufacturing cast steel materials, based on OKANO VALVE's philosophy that "superior valves are made by superior materials".

With the knowledge accumulated over several decades,OKANO VALVE has been acclaimed by our clients for using state of the art casting techniques and superior cast steel materials. So we provide not only valves,but also various types of steel casting.

Features of OKANO VALVE's casting steel
1.Products of superior quality / Rapid Product Delivery
Products of superior quality

Our industry leading products have undergone stringent safety and quality examinations to receive the requisite certification compulsory for Ultra Supercritical and Nuclear Power Plants.

Rapid Product Delivery

Okano Valve's manufacturing process is quite unique, being that we have the capability to design and manufacture products with the specifications requested personally by our clients. This in-turn reduces the lead time between the placement of an order and delivery of finished products.

2.Material Development

At our fully equipped engineering lab, we conduct various tests and research in an effort to develop new materials. At this lab, we conducted research on the development of 9Cr-1Mo steel, and in 1986, we perfected a technology that became the world's first. In 1996, we filed another application on a new material to the committee that revises technical standards for power generation. As a result, the current ignition standard "Fire SCPH91" was established.

3.Various achievement

Our extensive experience as an industry leader provides confidence for our clients that Okano Valve's products are the safety and of the highest quality.
