Needle valve vs ball valve is one of the most common RFQ questions on stainless manifolds.
Quick rule
- Need on/off with low pressure drop — stainless steel ball valve
- Need fine metering, sampling or gauge isolation — stainless steel needle valve
Do not throttle for long periods on a soft-seat ball valve — that is a needle job.
Ends and materials
Both families at FerruleX come in compression, female thread or weld-style ends depending on the SKU, in SS304 / SS316 / SS316L. High-pressure series exist in both lines — state design pressure on the RFQ.
