MEANLIN MEASURE 3/4" Pressure Vacuum Breaker Assembly, Brass Backflow Preventer Valve, Max 400Psi, for Lawn Irrigation System and Commercial Water Supply Systems with Pipe Freeze Protection Cover

["【Material】Constructed from thickened brass, it offers exceptional strength, corrosion resistance, and oxidation resistance, ensuring long-lasting durability without rusting. With a maximum working pressure of 150 PSI, a static pressure of 400 PSI, and a maximum operating temperature of 110°F, ensuring reliable operation in harsh environments.","【Backflow Prevention】Utilizing advanced pressure-vacuum backflow prevention technology, this device senses water pressure changes. When negative pressure or reverse water flow occurs, it automatically activates the venting mechanism to block the backflow path, preventing contaminated water from flowing back. This is crucial for safeguarding clean water sources.","【Easy Installation】Quick and easy installation without specialized tools significantly reduces construction time. The vacuum anti-pollution valve clearly indicates water flow direction in any installation orientation, simplifying configuration and facilitating installation.","【Application】Suitable for irrigation systems, commercial water supply, industrial pipelines, fire protection systems, and residential plumbing, effectively preventing contaminated water from entering the system. When used in outdoor garden irrigation systems, it prevents backflow of irrigation water into the water supply system, providing reliable control to protect water quality.","【Package Included】1* Pressure Vacuum Breaker Assembly, 1* Teflon tape."]
