Features and Benefits
• Forged carbon steel body.
• Pressure assisted fail open design.
• Modulating bimetallic regulator with fatigue-free stainless steel plates. No adjustment required.
• In-line adjustment available for characterization to process conditions and effects of back pressure.
• Discharges hot condensate at approximately 18°F (10°C) below saturation temperature throughout its operating range. One internal regulator for all pressure ranges.
• Operation is unaffected by water hammer or superheat.
• Self draining – will not freeze when installed in gravity drainage position.
• Automatically vents non-condensables and has a high (>3:1) cold water capacity for rapid start-up.
• Operates with zero steam loss throughout its operating range saving steam and money during the life of the trap.
• Easy in-line inspection and maintenance – no need to remove the trap from the piping to replace the internals.
• Can be installed in any position.
• Internal stainless steel strainer.
• Integral check valve design.
• Two (2) year guarantee.
