Trifunctional Air valve Barak D-040 PN16 plastic RM 2 ”black color, bronze base.
In the D-040 series trifunctional air valve, the characteristics of an automatic air valve are combined with those of an air and vacuum valve.
The air purge component is designed to automatically release small pockets of air that build up along the pipeline to the atmosphere when the system is full and pressurized.
The air and vacuum component has been designed to automatically discharge or admit large volumes of air, during filling or emptying of the pipeline. The valve will open to relieve negative pressures whenever water column separation occurs.
Applications:
- Pumping stations: after the pump and the retention valve (check).
- Downstream and upstream of the stopcocks.
- After deep well pumps.
- In long segments of pipes in constant decline.
- At high points along the line and in relation to the hydraulic slope.
- At the end of the lines.
- Before the counters (meters).
- In filters
Features:
- Working pressure: 16 bar
- Test pressure: 25 bar
- Maximum working temperature: 60°C
- Maximum momentary working temperature: 90°C
- Reliable operation reduces water hammer incidents.
- The dynamic design facilitates the discharge of air at high speed and prevents premature closure.
- Light weight, small size, simple and reliable structure.
- The drainage outlet allows excess liquids to be evacuated.
- The large size of the auto drain orifice in relation to the size of the valve body:
- Allows discharge of large volumes of air.
- Reduces the risk of obstruction by particles and impurities.
- Allows the use of the patented hermetically sealed drop-down rubber, less sensitive to pressure differences than direct float seals.
The body is made of highly resistant composite materials and all operating parts are made of specially selected, corrosion resistant materials.
Due to its low weight, the valve can be installed on plastic pipes or other lightweight materials.
