The valve body is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. Brass can be connected to copper, brass, plastic, aluminum, and welded steel. Fluorocarbon O-rings provide higher temperature and chemical resistance. It has female National Pipe Taper (NPT) threads on one end and male NPT threads on the other for connecting a male and a female threaded pipe. The NPT threads create a tighter seal than straight threads. The maximum pressure rating is 250 pounds per square inch (psi), and the maximum temperature is 250 degrees Fahrenheit. Check valves have two ports and restrict the flow of fluids and other loose materials through a pipe or passageway to one direction. Flow enters through one port and exits through the other, closing when flow reverses or stops. Two common types of check valves are ball cone valves and swing check valves. A ball cone valve utilizes a spring-loaded ball seated against a cone-shaped interior surface to stop the flow of fluid in a forward direction, and a swing check valve has a movable disc on a hinge to block reverse flow. Check valves are rated by their cracking pressure (the minimum upstream pressure required for the valve to operate), and they are used in various water, gas, air, and steam lines.Control Devices manufactures specialty valves, nozzles, and condensate traps. The company, founded in 1963 and headquartered in Fenton, MI, meets ASME standards. ## Features - About this item - P.when("ReplacementPartsBulletLoader").execute(function(module){ module.initializeDPX(); }) - Can be used as a tank check valve for small compressors or as a component in pneumatic circuits - Brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability - Fluorocarbon O-rings for higher temperature and chemical resistance - Female and male NPT threads for connecting pipes with different ends - Maximum pressure rating of 250 psi and maximum working temperature of 250 degrees Fahrenheit ## Images ![Control Devices-M2525-1WA Brass Ball Check Valve, 1/4" NPT Male - Image 1](https://images-na.ssl-images-amazon.com/images/I/61Z16Cr7YYL.jpg) ![Control Devices-M2525-1WA Brass Ball Check Valve, 1/4" NPT Male - Image 2](https://images-na.ssl-images-amazon.com/images/I/61x%2BO1apSAL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Does what it says, connected 2 air compressors with two of these *by C***N on Reviewed in the United States on April 10, 2020* I have two air compressors that operate at different pressures (130psi and 150psi) that I wanted the ability to run in parallel for increased CFM. I got these to prevent the higher pressure one from backfeeding into the lower pressure tank.I added shutoff valves to each and connected one compressor and left the other one open with nothing connected and no air leaked past when pressurized to 150psi so definitely does its job!9 CFM flow rate for each was just what I needed to pair a 1998 craftsman 8.6cfm@40psi compressor and my Central Pneumatic 7.5cfm@40psi. With these connected I can run my palm sander non-stop on two separate 120V circuits and have 60 gallons of capacity instead of needing to wire for 240V and get a 60 gallon ### ⭐⭐ Didn’t last long... *by M***T on Reviewed in the United States on April 25, 2020* This was exactly what I was looking for a compact in-line check valve. It worked fine for a few months and then it failed. It is installed downstream of a filter dryer and so I imagine it quit working because it is low quality. I gave it two Stars just because it didn’t work for more than a few months. Of course, it's so compact and inexpensive I might have to try another one and see if the first fail was a fluke or not. ### ⭐⭐⭐⭐⭐ Perfect for use on my remote aux air tank. *by N***A on Reviewed in the United States on June 6, 2018* Just what I needed for a fill port on my 40 gallon auxiliary tank for my air compressor. I built an remote aux air tank out of an old gas water heater tank to use as a secondary remote tank for my 4hp air compressor. Fitted the tank with regulator, dryer, oilier, safety valve, tank gauge & regulator gauge, dump valve for water drainage, and needed to make a fill port. I was using a small manual valve which soon became a PITA having to remember to open and close it when filling. My old original tank on the compressor leaks, so wanted to be able to shut the aux tank off also so it wouldn't bleed back through the leaky original tank. So, I chose this check valve to replace the manual fill valve. Works very well, and was sufficiently fast enough to fill the 40 gal aux tank. Filled it from zero to 110 psi in about 5 minutes, so that is good enough for me. Seems to hold well for now. Seems to be well made. --- ## 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.th/products/89274758-control-devices-m2525-1wa-brass-ball-check-valve-1-4](https://www.desertcart.co.th/products/89274758-control-devices-m2525-1wa-brass-ball-check-valve-1-4) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-26*
