Air Vents Installation

- Our Products
- Air Vent Selection

The presence of air in pipelines and in other irrigation devices can cause many problems:

• Reduced flow capacity, increased energy consumption,
• Water hammer and broken pipes,
• Faulty operation of filters, valves, etc.

All these troubles can be solve by a proper de-aeration of the System.

 AIR VALVES APPLICATION

Our Air Valves are a low cost solution to all these problems.

• They are used to release and admit air without any human assistance.
• Our line of products includes.
• Air release valves. With their small orifice, they are specially suitable for agricultural and landscape irrigation laterals they are used to continuously release entraped air under pression from irrigation devices. They should be located at the pump site downstream of all valves and at high points in a main or submain, slightly downstream of the high point.They continuously release accumulated air during system operation, and prevent water hammer.
  They maintain system design efficiency and provide system protection.
• Air/Vacuum valves, used to exhaust a large quantity of air, they allow air to re-enter after system shut down and prevent vacuum wich can damage filter and other irrigation devices. They also prevent contamination due to back-siphonage, and they protect gaskets, pipes joints, etc. against vacuum. They also provide protection from pipes, filters collapse.

WHERE TO INSTALL AIR VALVES

Air release valves.
They should be located:
• at the pump site downstream of all valves
• at all high points in a main or submain, slightly downstream of the high point (see fig. 1), and every 800 m on horizontal runs (see fig. 2).
• Air/Vacuum valves,
  Used to protect pipes against vacuum, they should be installed:
• at a point easily accessible for maintenance and repair.
• in a vertical position.
• at all high points of the hydraulical circuit.
