Air Vacuum Relief Valve Pvc

They help to incorporate both an air release valve and an air vacuum valve into 1 compact unit.

Air vacuum relief valve pvc. When system pressure returns to positive the vacuum relief air inlet valve closes air tight. Closes at 0 psi. 150 psi 70 f non shock. Clogged emitters can create substantial voids in coverage which can lead to dead plants and dry turf.

First a vacuum breaker is positioned on top of the supply tank to prevent implosion when the tank is drained. One of the key elements in a drip irrigation system is air relief. Use this air release valve for air venting while emptying or filling a closed tank. Clogged emitters can create substantial voids in coverage which can lead to dead plants and dry turf.

Suitable for all high points in a water distribution transmission system. Standard vacuum relief air inlet valves are designed to open with a minimal 1 4 psi pressure differential across the orifice. Reliable tank air venting. Product features available in dual.

Air release valves are used mostly to expel pockets of air at system start up but as shown in the diagram above they are also used in conjunction with vacuum breakers to eliminate siphon in piping systems. Pvc body with polypropylene ball. Installing automatic air relief valves on the end of lateral lines and emitterline will prolong the efficiency of your system. When the system pressure becomes negative the valve opens allowing air into the system to prevent a vacuum from building.

Installing automatic air relief valves on the end of lateral lines and emitterline will prolong the efficiency of your system. These air release vacuum valves feature cast iron construction with 316 stainless steel float and internal components.
