Marhynchus Air Check Valve Stainless Steel Hex BSPP Female Thread One Way Air Check Valve for Gas, Oil, Water Pipe Connection(1/4”)

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?

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?

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?

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

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.
