Featuring corrosion-resistant bronze and stainless steel components, it meets ASME Section IV safety standards and offers reliable, leak-free performance with standard 3/4" NPT female threaded connections for easy installation. ## Description This Apollo Valve 10-400 series safety relief valve has a bronze body, a 30 pounds per square inch (psi) relief pressure, a 3/4" female National Pipe Thread (NPT) inlet connection, and a 3/4" female NPT outlet. The valve's body and nozzle are bronze for resistant to corrosion, the seat is EPDM (ethylene propylene diene monomer) for resistance to ozone and aging, and the spring is stainless steel for resistance to corrosion. The valve can be used in operating temperatures up to 250 degrees F. This safety valve is American Society of Mechanical Engineers (ASME) safety rated for Section IV hot water heating boilers and hydronic heating systems.Relief valves remove excess pressure or vacuum from a system. The valve openings allow fluids or gases to escape to decrease pressure, and then close once the valve reaches the reseating pressure limit. They also relieve excess vacuum by opening to release a gas into the system and then closing after it reaches its low-pressure limit. Some relief valves have an adjustment mechanism to set the pressure where the valve opens, making it suitable for various applications. Relief valves are rated according to the volume of liquid or gas that can flow through them and the material that the valve is constructed from must be suitable for the fluid or gas, which may be corrosive or at an extreme temperature, in which it operates. Relief valves are used in a variety of applications, such as air compressors, petrochemical and chemical manufacturing, natural gas processing, and power generation.Apollo Valves manufactures ball, mixing, and relief valves, actuators, water gauges, marine fittings, heating and plumbing products, and backflow prevention. The company, founded in 1928 and headquartered in Matthews, NC, meets international standard International Organization for Standardization (ISO)/IEC standard 17025:2005. ## Features - Relief pressure preset of 30 psi for releasing excess pressure - 3/4" female NPT threaded inlet for connecting to a male NPT connection - ASTM B584 bronze body and nozzle and stainless steel spring for corrosion resistance - 250 degrees F maximum temperature for use in high-temperature applications - ASME safety rated for Section IV water heating systems ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008835PK6 | | Best Sellers Rank | #76,212 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #62 in Relief Valves | | Brand Name | APOLLO | | Connector Type | Threaded | | Customer Reviews | 4.5 4.5 out of 5 stars (173) | | Exterior Finish | Stainless Steel | | Global Trade Identification Number | 00670750493263 | | Included Components | 1040805 | | Inlet Connection Size | 0.75 inches | | Inlet Connection Type | threaded | | Item Dimensions | 9.7 x 7.1 x 6.6 inches | | Item Weight | 1.92 ounces | | Manufacturer | Conbraco | | Manufacturer Part Number | 1040805 | | Material Type | Bronze | | Maximum Operating Pressure | 30 psi | | Model Number | 10-408-05 | | Number of Items | 1 | | Number of Packs | 1 | | Number of Pieces | 1 | | Number of Ports | 2 | | Outlet Connection Size | 0.75 inches | | Outlet Connection Type | FNPT | | Size | 0.75 Inch | | Specification Met | Asme Section Iv - Hot Water Heating and Supply Boilers | | Thread Size | 3/4" | | Thread Type | NPT | | UPC | 670750493263 | | Unit Count | 1 Count | | Valve Type | safety relief valve | ## Product Details - **Brand:** APOLLO - **Exterior Finish:** Stainless Steel - **Inlet Connection Size:** 0.75 inches - **Inlet Connection Type:** threaded - **Item dimensions L x W x H:** 9.7 x 7.1 x 6.6 inches - **Material:** Bronze - **Maximum Operating Pressure:** 30 psi - **Number of Ports:** 2 - **Outlet Connection Size:** 0.75 inches - **Outlet Connection Type:** FNPT ## Images ![Apollo Valve 10-400 Series Bronze Safety Relief Valve, ASME Hot Water, 30 psi Set Pressure, 3/4" NPT Female - Image 1](https://m.media-amazon.com/images/I/41w5jWXOggL.jpg) ## Frequently Bought Together - Apollo Valve 10-400 Series Bronze Safety Relief Valve, ASME Hot Water, 30 psi Set Pressure, 3/4" NPT Female - AMTROL 102-1#30 EX-30 30 Extrol Expansion Tank - Taco 400-4 1/8-Inch-NPT Float Air Hy-Vent --- ## 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.tn/products/4037747-apollo-valve-10-400-series-bronze-safety-relief-valve-asme](https://www.desertcart.tn/products/4037747-apollo-valve-10-400-series-bronze-safety-relief-valve-asme) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-11-10*
