Ball Valve

The element with an opening is held with two pieces of valve seats and it rotates 90 degrees to be open and close.

The rotary type (or quarter-turn type) whose stem spins on the spot makes it easy to fully open and close; it is excellent in operability and visibility.

In addition, it has little irregularities inside of the valve and causes quite little pressure drop, which is one of the exceptional features of the valve. There are several types such as "standard bore" or "reduced bore," in which the opening hole diameter is smaller than the inside diameter of the valve.

We deal with valves compatible with special requirements such as high pressure gas certified valves and oil prohibited products.
