Automat HT-88CPM 1 Inch Plastic Continuous Acting Air Release & Vacuum Relief Valve

Its proven design provides more air release capacity than other air vents of similar size. Being a safety valve, it ensures maximum protection of the irrigation system with proper sizing and placement. Being a larger capacity valve, it dampens water hammer thereby preventing pipes and fittings from cracking or bursting.FeaturesManufactured out of Durable, Weather Resistant and Non- Corrosive reinforced Polyamide (Nylon).Threaded Elbow Outlet.FunctionsExpulsion (Kinetic Air): When the pipe is being filled, the air release valve remains open expelling all the surplus air outside the installation. When the . Pipe is full of water, air release valve closes tightly. Air Admission (Air Intake): While negative pressure (pipe vacuum) the air. Release valve opens to allow the air to go inside the pipe. This system avoids possible damages in pipes and accessories. Expulsion of the residual air (Automatic Air): The air release valve constantly releases the residual air generated in the installation (due to water level changes in reservoir during fertigation / leakages in suction pipe, fittings), expelling air even when the system is under pressurized condition.
