Superior air intake / discharge function |
| |
In spite of negative pressure, the float is not easy to be sucked up during air discharge. Consequently, high volume air discharge can be generated, shortening
water flow time.
|
| |
|
|
Small size, light weight and solid structure |
| |
With a proper pipe-shaped appearance, the body is light and handy. |
| |
|
|
Main part is made of stainless materials |
| |
Strictly selected plastics is used for the main part, durable for years. |

Durability for water halting section |
| |
Specially developed rubber is used for the water halting section that provides
anti-corrosion effect; therefore, stickiness can be avoided despite wear
and tear, ensuring smooth air intake and discharge. High performance on water halting will last. |

|
The sub-valve in the pipeline jams no obstructions |
| |
Small size, easy to use. A ball valve with little resistance to fluid is used to fulfill its function. |

Superior air intake/discharge function |
| |
It is an often-seen phenomenon in a pipelining work site that slow motion of air release valves leads to inefficiency of drainage. We have manufactured
rapide air release valves with excellent capability to solve the problem mentioned above.
They are not only light-weighed but handy
and ideal as well. |

 High volume discharge
Volume of air can be discharged
from large orifice when the pipeline
is filled water. The lift valve is down
with the large air vent wide open. |
 Filling condition
Water enters the interior via surrounding
small orifices inside the valve when
flowing into the air release valve.
The mobile valve lifts to close the
air vent and avoid water leakage. |
 Low volume discharge
In the pipeline filled with water,
the float drops with water going
down to open the small air vent
for low volume air discharge. The
float low volume air discharge.
The float rises after air discharge
is completed, to close the small air
vent. The process will be repeated
air vent. The process will be repeated
to release the air in the pipeline. |
 Air intake
When water is forced out of the pipeline
the mobile valve and float drop, opening
the large air vent with high volume
air intake. This movement will
improve efficiency of water release
and lower the pipeline pressure
to avoid damage. |
