This Control Devices in-tank check valve is a poppet-type valve, and may be disassembled for cleaning or repair 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. This valve has a glass-filled polytetrafluoroethylene (PTFE) poppet with eight discharge holes for quiet operation, and stainless steel spring. It has a compression connection on one end for a leak-proof connection without the need for additional joining preparations, and female NPT threads end on the other for connecting to male threaded pipes, creating a tighter seal than straight threads. The maximum pressure rating is 450 pounds per square inch (psi), and the maximum working temperature is 400 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.

I initially found this valve on a well known Industrial Supply site . Came over to Amazon and they had it ! Much quicker delivery (2 days) through Amazon.com and cheaper too . I also ran the air charge inlet line to the bottom of the tank instead of right next to the air outlet for less moisture in my lines .Read more ›
The 1/8 NPT port on the side is easy to access and unobtrusive for those not needing an unloader hookup. I don't know why the picture shows an unthreaded plug sticking way the side.
The valve body is large in diameter and discharges to the side. As advertised, this model is best used in a tank rather than a pipe or fitting. It does, however, work just fine in any orientation.
At low flow rates there is an audible fluttering of the valve (no issue). It is a fairly flow restrictive design, but it seals well and does the job. I recommend this to anyone needing a 1/2 npt check valve for a tank.

This was a replacement for a similar item purchased last year, which did not turn out to be solid brass after all, and quickly failed as a result. Read morePublished 5 days ago by Sheryl S.
Perfect fit, exact replacement for my old Sanborn compressor.
Works exactly as described! One way valve, keeps air in my tank and out of my pump, exactly as pictured!Published on March 7, 2014 by Vegerito
