TKV AUTOMATIC AIR VALVE(WITH COMBINATION)DN50 to DN200, PN10 & PN16 Pressure Rating
Application
The primary application for air valves on water transmission lines and sewage force mains, thus;
A.Allowing the air that is being pushed ahead of the incoming liquid to escape from the system and ensure a complete filling of the pipeline.
B.Allowing air to refill the system to replace the out flowing liquid to prevent vaccum formation during draining operation.
C.Often, Air valves are installed along with air release valve or as combination valves to not only function during filling/draining but also vent air pockets during operation.
Main features & Benefits
* During the exhausting sequence, the air flowing around the float ball produces a resultant downward force which maintains the ball in the open position.
* The kinetic design of TKV valve prevents premature valve closure/blow shut while exhausting air up to sonic speed, therefore can be operated at higher differential pressure or exhausting a greater volume of air than those conventional air valve.
* The buoyant force of the float ball will seal the exhaust orifice when water reaches the ball.
* Full length guide bush ensure proper seating even valve is not perfect vertically installed.
* Built-in protection grid on air valve prevents anything that longer than 5mm in diameter from entering the system during draining or when the system is empty.
* Rubber cushion protect float ball from damage during sudden vaccum.
* During operation, air release valve capable of venting out air pockets that trapped in the water, thus increasing the system efficiency.
* Specially designed pivot arm link for air release valve able to amplify the buoyant force till 15 times, thus enable orifice button to seal orifice more tightly.
* Spherical, stainless steel float ball for strongest possible shape, tested to 70 bar.
* Fusion bonded epoxy powder(FBE)coating body, able to withstand mostly all harsh condition and suitable for drinking water.
