Advantages of Ball Valves


There is no need for a higher and powerful pump to move the fluid and gas. It also means the change of pressure from high to low is minimal, ensuring the smooth running of the pipe components.

No Stem

The valve does not include a stem part that pops up or down depending on the movement. Hence, no gas or liquid gets out of the pipe when the valve is shut off or turned on.

Easy To Operate

It only takes a 90°-turn for the valve to shut down or turn on.


This type of valve does not cost much yet lasts for a long time. There are more choices because of varied designs.


This valve supports high pressures and temperatures. It can withstand up to 700 bars and 200°C.

Easy To Fix

Because of its simple design, especially the top entry, fixing and assembling them is easier compared to other valve types.
