Okano Valve Gate Valve

Made in Japan
Manufacturer: OKANO VALVE MFG. CO.

Gate valves vertically partition the path of the fluid using a gated structure, creating a straight-line flow of fluid.
Although these valves keep pressure loss and fluid resistance at a low level, they can only be used for on-off applications.

Gate valves allow for various applications and are thus used in a wide range of fields. At Okano, we also manufacture valves that meet highly specialized requirements.

The reactor recirculation pump (RRP) discharge valve is a foremost example. This is a type of gate valve with an array of unique structural features, including one that reduces valve operation time to enable rapid closure in the event of an emergency.
