About this item

  • 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


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.

Looked around to replace one that had a broken spring. This was an exact match. Does it's job well.

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.

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
