Product Description
The Control Devices ball-type check valve provides tight sealing, and can be used as a tank check valve for small compressors or as a component in pneumatic circuits. 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.

Customers like the value, quality and performance of the check valve. For example, they mention it's cheap, works great and is of good quality. Opinions are mixed on leakage and air pressure.
AI-generated from the text of customer reviews
Customers are satisfied with the performance of the valve. They mention that it works great on the inlet of their large secondary air tank connected to their air compressor. It also works perfectly on their air pump and allows two compressors to run separately at the same time. The check valve works great, and it's easy to use. Some customers also say that it'll keep pressure in their antennas while not allowing them to drop. Overall, customers are happy with their purchase and recommend it to others.

Customers like the quality of the check valve. For example, they say it's a good product, well-made, and reliable. Some mention that it has a plastic part in side. Overall, most are satisfied with the product's quality.

Customers are mixed about the leakage of the valve. Some mention that it doesn't leak, holds air perfectly, and provides a completely leak free seal. However, others say that it still leaks, and immediately began to leak air in the reverse direction when the pump is disengaged.
"...I am extremely happy so far with my purchase. These valves seal extremely well. I do not lose any air overnight...." Read more

Customers have mixed opinions about the air pressure of the valve. Some mention that it holds air pressure great and effectively, while others say that the last two check valves will not hold back pressure below approx. 15 psig, causing the system to lose pressure.
"...They have very low pressure to open (you can blow into them and they will open) and very high flow rate in the direction of flow...." Read more
"...Why? Because the release pressure seems very high...." Read more

The coating of sealant is as expected from this sort of product. I did a minor remove of excess sealant just to not fight the threads. This is really the only issue I think could be improved upon but is extremely difficult with a machine doing the job. My recommendation would be to apply no thread sealant and let the end user appropriately seal the fitting.
Why? Because the release pressure seems very high. I can sneak a small probe in past the plastic retainer, and I can tell that the spring isn't very stiff, so perhaps it just needs some lubrication, but I really doubt this'll work. I might be surprised, though; we'll see.
