Why This Model Is Special

The KCB1DOA2D5P10000 variant is not widely listed in Swagelok’s standard catalogs. It appears to be a special configuration—likely built to customer-specified outlet ranges, seat materials, or cleaning standards. This makes it hard to source, even directly from Swagelok, without a custom order.

Performance & Build Quality

Swagelok regulators are known for:

• Tight pressure control even under fluctuating inlet conditions

• Corrosion resistance via 316 SS construction

• Compact footprint for tight-panel installations

• High cycle life with minimal maintenance requirements

Compared to competitors like Parker Veriflo, Tescom (Emerson), or Bürkert, Swagelok’s KCB series often offers:

• Better sealing integrity at low pressures

• Shorter lead times for replacement components

• More consistent Cv values in low-flow regimes

• Widely available maintenance kits and global support
