Description

Pragati air release valve has features of both an air release and vacuum relief valve. Our innovative float is designed to automatically release accumulated and entrapped air during the filling and admit large volumes of air during the draining of pipeline of piping system. High velocity air will not blow the float shut. Water will li the float which seals the valve. The smooth discharge of air reduces pressure surges and other destructive results.

Special Features and Benefits

• Manufactured from high performance polypropylene compound material and all operating parts are made of specially selected corrosion resistant material.
• Carbon black and UV stabilizers resist ultraviolet rays and prevent degradation of PP in sun light exposure
• Compact, dynamic and innovative float design allows for high velocity air discharge while preventing premature closure.
• Large orifice discharge and intake air at high flow rates.
• Light weight, small dimensions, simple and reliable structure.
• With close strainer design restricting entrance of outsider particles.
• Pragati air valve is designed for removal of Entrapped air during watering system start up, which prevents airlock in pipeline and inaccurate flow meter readings.
• Air valve also provides positive vacuum relief when pipe is draining. Which minimize water hammer and chance of collapse of pipes caused by a sudden reversal of water flow.

Typical Application

• Micro Irrigation System
• Horticulture and Agriculture
