## Questions & Answers

**Q: What is the free flow cfm rating? i want to use it for a large compressor  -10 cfm - need to allow volume by this valve without flow restriction?**
A: I don’t know the cfm but it works well with my compressor. I have a vmac gas driven screw compressor tankless but I added a 30 gallon tank I use the check valve to stop back feeding from the tank

**Q: What is the opening pressure?**
A: No pressure needed, until there is back pressure. I use on air line. Stops the air from back feeding. I use 2 air compressors.

**Q: Operating and max pressure of one way check valve. is it rated for hpa?**
A: Not sure what you mean by hpa but it will work for anything 100psi.

**Q: It says it’s for water in four places and only one place for gas which is it what is the operating pressures style of check valve? Ball or flap**
A: It’s flat valve not ball but I’m not sure what pressure it is. I used it with 140psi air pressure with no problem.

The size fits perfect,don't know if it will pop off yet,haven't aired it up yet

### ⭐⭐⭐⭐⭐ Simple, but exactly the solution I needed.
*by J***N on May 25, 2023*

It does exactly what it's supposed to do.

### ⭐⭐⭐ Is well built, but required excess thead tape
*by M***B on March 12, 2023*

Appears well built, however it required 6 wraps of premium thread tape on each set of threads to seal. Threads are cut a hair to wide. the problem is its British Standard not National Standard pipe thread.
