Featuring a fast inlet and exhaust mechanism with a reliable float design, it prevents vacuum damage and air pockets, extending system life and reducing maintenance. Its universal NPT threading ensures easy installation across drip irrigation, solar drain-back, and pool overflow setups, making it an essential upgrade for efficient, worry-free water management. ## Description Name: Drip Irrigation Air Relief Valve Material: PA Interface: 3/4 inch NPT Net Weight: 92 g Working pressure: 0.2-15bar Exhaust area: 288mm Exhaust area: 122x58x58mm Air/Vacuum Vents working principle - Irrigation system water injection. System water injection process, a large amount of air from the power type fast air inlet exclusion, water try their best to air valve chamber after the float rose with the liquid level, close the fast inlet and exhaust port. Gas dynamics valve design and float anti-blow-up design can prevent the float from being blown up by high-speed airflow before the water enters the air valve, resulting in premature closure of the exhaust port System under pressure. Powered intake valve remains closed when system is under pressure System evacuation. A differential pressure is created when the system is evacuated and the air pushes down on the float. The power type fast inlet and exhaust port opens and air enters the air valve to avoid the formation of negative vacuum pressure in the system Reduces maintenance requirements and extend drip system life Smooth and reliable operation Eliminates air pockets within a system zone Releases air from the drip line when the zone is turned on Allow air to freely enter the system when the zone is shut down Ball float design offers perfect sealing under very low system pressure Easy to handle and maintain Constructed of UV-resistant, durable plastic material to withstand the most adverse conditions Install the Air Vacuum Relief Valve after the drip zone, along the drip line laterals and at the highest point in the drip system layout. Install one Air Vacuum Relief Valve per zone. Review: Essential for Drain-Back Solar Systems — Reliable Vacuum Break with Simple Noise Fix - I purchased this 3/4" Air and Vacuum Relief Valve to integrate into my DIY solar hot water heater system. Its primary role is to ensure proper vacuum release for reliable drain-back to the solar collection tank—an essential function in this type of system. When the pump is off, this valve breaks the vacuum formed during water return from the solar collector, allowing the water to drain back through the pump. This effectively clears the collector and helps prevent freezing conditions. This valve performs that task very well. The only minor drawback is that it can produce a suction noise, which I’ve demonstrated in the video included with this review. Fortunately, this can be mitigated by placing the unit inside a larger pipe filled with insulation, or by removing the top cap and inserting a small piece of insulation inside. Overall, I’m very satisfied with this valve and highly recommend it for anyone building or improving a drain-back solar hot water system. Review: Works very well - Works great on my pool overflow. Keeps all the water from siphoning out of the pool on the super rainy days. ## Features - Resistant Materials - Valve of material PP with corrosion, acid, alkaline resistant features to be long lasting - Powerful Fast Inlet and Exhaust Valve - Automatically exhaust and intake air, used for the intake and exhaust of the pipe and irrigation system - Easy to install - The perfect irrigation accessories, NPT screw thread - Widely Used - Pipe venting valves for grassland, home gardening, agricultural drip irrigation systems - Excellent Customer Service ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CQZ1ZMYY | | Best Sellers Rank | #92,612 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #442 in Automatic Irrigation Accessories | | Brand Name | UPLYKKE | | Customer Reviews | 4.2 4.2 out of 5 stars (37) | | Exterior Finish | Plastic | | Included Components | air relief valve | | Inlet Connection Size | 0.75 Inches | | Inlet Connection Type | National Pipe Tapered | | Item Dimensions | 2.2 x 2.2 x 5 inches | | Manufacturer | UPLYKKE | | Material Type | Polypropylene | | Maximum Pressure | 15 Bars | | Model Number | IE0134 | | Number of Ports | 2 | | Outlet Connection Size | 0.75 Inches | | Outlet Connection Type | NPT | | Size | 3/4 inch | | Specification Met | ASTM, ISO 9001, MSS SP 72 | | Thread Size | 0.75 inches | | Thread Type | NPT | | Unit Count | 1.0 Count | | Valve Type | Pressure Relief Valve | ## Product Details - **Brand:** UPLYKKE - **Exterior Finish:** Plastic - **Inlet Connection Size:** 0.75 Inches - **Inlet Connection Type:** National Pipe Tapered - **Item dimensions L x W x H:** 2.2 x 2.2 x 5 inches - **Material:** Polypropylene - **Maximum Operating Pressure:** 15 Bars - **Number of Ports:** 2 - **Outlet Connection Size:** 0.75 Inches - **Outlet Connection Type:** NPT ## Images ![Air Relief Valve 3/4 inch Air and Vacuum Release in The Irrigation Water Saving Agriculture Drip Irrigation System Protected Outlet - 1 Pcs - Image 1](https://m.media-amazon.com/images/I/51YXicUjvUL.jpg) ![Air Relief Valve 3/4 inch Air and Vacuum Release in The Irrigation Water Saving Agriculture Drip Irrigation System Protected Outlet - 1 Pcs - Image 2](https://m.media-amazon.com/images/I/719vgyx5yCL.jpg) ![Air Relief Valve 3/4 inch Air and Vacuum Release in The Irrigation Water Saving Agriculture Drip Irrigation System Protected Outlet - 1 Pcs - Image 3](https://m.media-amazon.com/images/I/61nT60-2z0L.jpg) ![Air Relief Valve 3/4 inch Air and Vacuum Release in The Irrigation Water Saving Agriculture Drip Irrigation System Protected Outlet - 1 Pcs - Image 4](https://m.media-amazon.com/images/I/819CgixyMQL.jpg) ![Air Relief Valve 3/4 inch Air and Vacuum Release in The Irrigation Water Saving Agriculture Drip Irrigation System Protected Outlet - 1 Pcs - Image 5](https://m.media-amazon.com/images/I/51PrtdcMqEL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Essential for Drain-Back Solar Systems — Reliable Vacuum Break with Simple Noise Fix *by J***G on August 1, 2025* I purchased this 3/4" Air and Vacuum Relief Valve to integrate into my DIY solar hot water heater system.
