It has a cast bronze body, a 15 pounds per square inch (psi) relief pressure, a 3/4" male National Pipe Thread (NPT) inlet connection and 3/4" female NPT outlet, and a PTFE (polytetrafluoroethylene) seat. The valve's body and nozzle are bronze and the spring is steel for resistance to corrosion. The flat seat is a PTFE-faced disc for positive seal, resistance to moisture and high temperatures, and positive drainage of condensate from the seat area. The valve can be used in operating temperatures up to 250 degrees F. This relief valve is American Society of Mechanical Engineers (ASME) safety rated for Section IV heating boilers and is suitable for low-pressure steam heating and supply boilers. 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. ## Features - Relief pressure preset of 15 psi for releasing excess pressure - Cast bronze body and steel spring for corrosion resistance - 3/4" male NPT threaded inlet for connecting to a female NPT threaded connection - Flat seat, PTFE-faced disc for positive seal - ASME safety rated for Section IV heating boilers ## Images ![Apollo Valve 13-510 Series Bronze Safety Relief Valve, ASME Steam, 15 psi Set Pressure, 3/4" NPT Male x Female (4-(Pack)) - Image 1](https://m.media-amazon.com/images/I/31-nHP8rBeL.jpg) ![Apollo Valve 13-510 Series Bronze Safety Relief Valve, ASME Steam, 15 psi Set Pressure, 3/4" NPT Male x Female (4-(Pack)) - Image 2](https://m.media-amazon.com/images/I/31-nHP8rBeL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Low Cost Replacement valve *by E***D on Reviewed in the United States on January 11, 2013* When my steam boiler started releasing steam (and lots of it) at 2 psi, I knew the Safety Relief Valve was shot, even though the boiler has only been in operation 4 years. I searched for a replacement and found similar products that were much more expensive. This one looks the same and cost much less. I know it is a safety item, but feel confident it will work properly. It was not difficult to install if you know how to solder copper pipe and fit perfectly. ### ⭐⭐⭐⭐⭐ Five Stars *by R***N on Reviewed in the United States on March 2, 2017* Pretty simple - it does what the manufacturer said it would do ### ⭐⭐⭐⭐⭐ Quality product *by J***M on Reviewed in the United States on November 8, 2014* Worked flawlessly 15 psi on the dot and it popped. Reseats nicely as well with no drips.good job Apollo! --- ## 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/124041743-apollo-valve-13-510-series-bronze-safety-relief-valve-asme](https://www.desertcart.tn/products/124041743-apollo-valve-13-510-series-bronze-safety-relief-valve-asme) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-28*
