VP DOUBLE EFFECT AIR RELEASE VALVES

√ WITH VP AIR RELEASE VALVES YOUR SYSTEM IS SAFE It protects you from problems caused by the existence of air. VP air release valves prevent breakages due to the accumulation air, causing it to exit the pipes at the same speed at which the water enters when the system is activated. Any type of air pockets or bubbles that occur at the elevated points are fully eliminated and the passage section is reduced. It allows air to re-enter the main and secondary pipes, preventing the formation of a vacuum, which eliminates the siphoning of mud or dirt by the emitters and the collapse and crushing of the pipes.

√ WAVE SYSTEM CLOSURE Exclusive “wave system” closure patented by GESTIRIEGO. This guarantees the effective working of the air release valve, allowing the expulsion of high air flow rates when the system is under pressure and ensuring a low pressure closure.

√ A SINGLE AIR RELEASE VALVE HANDLES THE 3 OPERATING PHASES OF YOUR SYSTEM WITH A SUPER REDUCED SIZE Filling the system: the air is extracted efficiently since the float is kept away from the kinetic air outlet hole. When the water reaches the VP air release valve, the thrust of the float lifts the shutter, thus throttling the silicone pipe and closing the kinetic and automatic air outlet holes. In this situation, the air release valve is completely air tight from a pressure of 0.2 atm. Emptying the system: when the system is emptied, the float descends next to the shutter, causing the opening of the kinetic hole of the air release valve and allowing the air to be sucked from the outside, thereby preventing the pipes from being crushed. Operating under pressure: when the air pockets reach the air release valve, the float descends, deploying the silicone pipe, while the shutter closes the kinetic air outlet hole, allowing the air to automatically exit through the silicone pipe.

√ RESISTANT MATERIALS High resistance to pressure and chemical agents dissolved in irrigation water. Both the gasket and the pipe are made of silicone, much more resistant to these products than materials such as EPDM or NBR. In this way, the working of the air release valve can be guaranteed for a longer period than other similar products on the market.
