Viair 92831 Details

Customer Q&A - Viair 92831

What is the cracking pressure of the valve?

We spoke with Viair and they advised the cracking pressure is very low, only a few PSI on the compressor check valves.

Which way does the air flow on this check valve?

The Viair compressor check valve 92831 flows from Female to Male.

Hi, I'd like to know which direction these check vavles are free flowing for a compressed air application, and if it is spring loaded or not for a vacuum application? If they are spring loaded, then what is the cracking pressure to open it? In other words, is it light enough to use with vacuum?

The Viair compressor check valve is a one way check valve that is designed to be used with air compressors. It will not work and is not designed to work with vacuum applications. Thank you!
