Armstrong 11/22/13-LD Free Floating Lever Drain Trap

Fits liquid drainage on steam and process systems where you need stainless 11-LD / 22-LD / 13-LD free-floating guided lever drain traps rated for saturated service up to 570 psig class.

Key advantages

• Models — 11-LD, 22-LD, 13-LD stainless free-floating guided lever liquid drain traps
• Pressure — Valve/seat/leverage design for saturated steam service up to 570 psig (39 barg)
• Mechanism — Elliptical float with high leverage and guidepost for leak-tight closing
• Connections — Flanged, screwed, socketweld options
• Certifications — CE, CRN, PED

Typical applications

• Draining liquid from steam headers and drip legs.
• Process liquid drain points needing stainless guided-lever traps.
• Projects specifying CE/CRN/PED drainers.

Selection guide

• Model — 11-LD vs 22-LD vs 13-LD for capacity/connection
• Pressure / load — Confirm differential and condensate load
• Connection — Flanged vs screwed vs socketweld
• Material — Stainless body family as standard

Common mistakes

• Sizing only on pipe diameter — use condensate load and differential pressure.
• Using a steam trap selection table without checking liquid-drainer orifice capacity.
• Ignoring orientation/installation limits for the float mechanism.

When to RFQ / what to tell us

1. Model preference, design pressure, and condensate load.
