Featuring a heavy-cast brass body and full flow-control, it ensures precise water management and durability. Ideal for cold water use, it meets anti-siphon standards and is easy to install with compatible fittings, making it a trusted choice for professional-grade lawn irrigation systems. ## Description Product Description The manual anti-siphon valve features a combination of an inline forward flow valve and an atmospheric vacuum break which prevents water flowing from the irrigation system into the culinary system. This type of valve is most common in California. In other states it is common for a single backflow prevention device to protect the entire system at the mainline point of connection. In order to function properly, an anti-siphon valve should be installed at least 12 inches above the highest head in the zone which it controls. This typically requires the anti-siphon valve to be installed above-ground on risers. The anti-siphon valve features an easy-to-rotate flow control handle. We recommend that you use a steel sprinkler key for hard-to-reach places and PVC-Lock fittings for fast, glue-free installation. For outdoor irrigation use with cold water only. From the Manufacturer The Brass Anti-Siphon Control Valve is designed to prevent contaminants from entering the main water supply. It has a heavy-cast brass body and makes precise flow adjustments. ## Features - Designed to prevent contaminants from entering the household water supply - Full flow-control and anti-siphon valve - Heavy-cast brass body - For outdoor use with cold water only ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00004S22H | | Best Sellers Rank | #33,591 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #91 in Automatic Irrigation Sprinkler Heads | | Brand Name | Orbit | | Connector Type | FPT | | Customer Reviews | 4.6 4.6 out of 5 stars (343) | | Exterior Finish | Brass | | Global Trade Identification Number | 00046878510166 | | Inlet Connection Size | 0.75 inches | | Inlet Connection Type | Female Iron Pipe | | Item Dimensions | 12.38 x 4.5 x 4.75 inches | | Item Type Name | Anti-Siphon Control Valve | | Item Weight | 1.8 pounds | | Manufacturer | Orbit | | Manufacturer Part Number | 51016 | | Material Type | Brass | | Model Number | 51016 | | Number of Items | 1 | | Number of Pieces | 1 | | Outlet Connection Size | 0.75 inches | | Outlet Connection Type | FNPT | | Size | 0.75 Inch | | Specification Met | Anti-Siphon Valve Standard | | Thread Size | 3/4 inch | | Thread Type | FPT | | UPC | 046878510166 | | Unit Count | 1 Count | | Valve Type | Anti-Siphon Valve | ## Product Details - **Brand:** Orbit - **Exterior Finish:** Brass - **Global Trade Identification Number:** 00046878510166 - **Inlet Connection Size:** 0.75 inches - **Inlet Connection Type:** Female Iron Pipe - **Item dimensions L x W x H:** 12.38 x 4.5 x 4.75 inches - **Material:** Brass - **Outlet Connection Size:** 0.75 inches - **Outlet Connection Type:** FNPT - **Specification Met:** Anti-Siphon Valve Standard ## Images ![Orbit 51016 3/4" FPT Brass Manual Anti-Siphon Sprinkler Valve - Image 1](https://m.media-amazon.com/images/I/81qaz667sGL.jpg) ![Orbit 51016 3/4" FPT Brass Manual Anti-Siphon Sprinkler Valve - Image 2](https://m.media-amazon.com/images/I/41UCtf3oLKL.jpg) ![Orbit 51016 3/4" FPT Brass Manual Anti-Siphon Sprinkler Valve - Image 3](https://m.media-amazon.com/images/I/6154NXqWUoL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Frequently Bought Together - Orbit Sprinkler System 3/4-Inch Brass Anti-Siphon Control Valve 51016 - Orbit 57253 3-Valve Heavy Duty Preassembled Manifold - Valve Box Platform for Orbit 12" Sprinkler Control Boxes --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/4570771-orbit-51016-3-4-fpt-brass-manual-anti-siphon-sprinkler](https://www.desertcart.co.za/products/4570771-orbit-51016-3-4-fpt-brass-manual-anti-siphon-sprinkler) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-21*
