CVH Series Inline Check Valve, 1-1/4 NPT Ports, Up To 200.00 GPM & 6000.00 PSI

This valve has 1-1/4 NPT threads.

At 6000 PSI maximum working pressure, a system running steady at 5500 PSI sits comfortably within what this valve is rated to handle. The alloy steel body and precision hard seat piston seal are built to hold up under sustained high pressure without leaking down. The hardened poppet check element is part of what keeps things sealed tight even when you're pushing it consistently near the top of the range.

At sustained operation, 6000 PSI is the rated working limit for this valve. That said, the CVH Series is built from alloy steel with a burst pressure rating of 19,500 PSI, so there's substantial margin above the working range. For smaller sizes in this series, the spec notes capability up to 10,000 PSI at a reduced safety factor. At 1-1/4 inch though, the 6000 PSI working pressure is what you want to stay within for reliable, long-term use.
