Product Features

  • Poppet-type in-line check valve
  • Installs in the discharge line of the compressor in cases where an in-tank valve will not fit
  • Made from brass for higher corrosion resistance than steel; PTFE poppet and stainless steel spring
  • Compression connection on one end and female NPT threads on the other for connecting to male threaded pipe
  • Maximum pressure rating of 450 psi; maximum working temperature of 400 degrees Fahrenheit

Product Description

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.

Connector Type: NPT Female x NPT MalePart Number: P5050-1EPOverall Length: 3 Verified Purchase
I rebuilt my old 60 gl. single stage Porter Cable compressor that I call "Franken-Pressor" recently , adding larger 1/2" NPT "Black Pipe" lines , pump and a true 5hp. Continuos Duty Leeson Motor . This allows the compressor from getting so hot they go Nuclear and literally have a melt down (mine did twice in 10 years of heavy use).The compressor needed a check valve to relieve the back pressure on restart (without the valve my compressor (not a shop duty but great for home use) could not restart period (almost "Smoke-Checked" the Leeson with cut-off set at 125 psi). I finally figured out I needed a one-way check valve so there was no load on the electrical motor from the compressed air backing up into my twin cylinder pump , and this valve is rated to 450psi back pressure! Finding a valve was a bit of a chore as all lines were 1/2" steel pipe for greater volume . So far I've burned 2 pumps up and almost burned up my new Leeson 5hp. motor with those dinky 1/2" copper tube lines (WHAT A JOKE !) . I do body work etc. and I really "tax" it's capability . Yeah , I know,, I need a Two-Stage but My Ol' Man used to say "Wish in one hand and do something really "foul" in your other hand and see which fills up faster" ! ;-)
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 .

I used this on my Ingersol Rand air compressor instead of paying a lot more fro their OEM type fitting. Easy to install into the tank. Their old fitting can be reused on top of this one by cutting the bottom of it off right below the pipe threads (where the check valve part is) and then the safety valve is still there and the unloader fitting will reconnect with out any adapters. Note that this check valve doesn't have a provision for a safety valve made into it and it's tapped 1/8 npt in the side and the IR valve is a flair. That's why I cut and reused part of the old original valve. I saved $40 to $50 doing this and everything fit back into place.

I purchased this to fix my older Jeannie Air compressor that had developed a pressurized leak out the Overload release valve. I had been living for a few years with a rag wrapped around valve and vise grip clamped to minimize the leak but after being annoyed with it pushing oil out crankcase I decided to find a solution and this was it. I really needed the 3/4 thread into tank and 1/2 thread for air tube which is else where on amazon but even with the 1/2 to 3/4 reducer fitting still was cheaper and faster. Highly recommend

Connector Type: NPT Female x NPT MalePart Number: P5050-1EPOverall Length: 3 Verified Purchase
The unit is of robust construction. The internals appear clipped together which allows future cleaning or disassembly. The brass threads are well cut, and the sealing stripe is thick enough to work. Everything seals gas-tight out of the box. The plastic bits have no issue with hot gas and appear to be made of the right stuff.
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.

I purchaced this to upgrade my compressor from 3/8" compression fitting to 1/2" npt. Works great, comes pre-coated with pipe sealant. Has 1/8" npt outlet for unloader line. Holds 145 psi for weeks! Mine even looks better than the one in the above picture!

Connector Type: NPT Female x NPT MalePart Number: P7575-1EPOverall Length: 3-1/4 Verified Purchase
Ordered this valve to replace existing tank check on a Quincy two-stage compressor. Reason for replacement was that the original valve leaked tank pressure at the rate of about 3 psi/day (32 gallon tank). After replacing with this valve, and extensive testing, I found the leak rate had increased to 5psi/day. Leakage was all from the valve! I removed and replaced with the original valve, after refacing the teflon poppet and cleaning. I find the leak rate unacceptable for a new valve.

Valve works perfectly, and did not require any modificaiton to compressor plumbing during install. No leaks at any pressure (there does not seem to be a minimum pressure to hold the checkvalve closed).
