A check valve and a ball valve solve different problems on stainless tubing and pipe.
Different jobs
| Valve | Job |
|---|---|
| Ball valve | Manual shutoff / isolate a branch |
| Check valve | Block reverse flow automatically |
A check valve is not a substitute for isolation. If maintenance must open the line, keep a ball valve in series.
FerruleX options
We supply stainless steel check valves with compression or female thread ends, plus split-body styles for service, and ball valves for shutoff. Typical check-valve catalog pressure is about 2000 PSI — confirm cracking pressure on the RFQ.
Spec tip
Always mark flow direction on the PO. A reversed check valve looks installed and still stops the process. Start with the check valve category or contact for a mixed valve kit quote.
