Series 46
Bimetal Steam Traps
A rugged all stainless steel bimetal trap that discharges subcooled condensate, handles dirt well and tolerates superheat, for tracing and drip service.
- Max pressure
- 300 psi (21 bar)
- Max temperature
- 750 °F (400 °C)
- Body rating
- ANSI Class 300
- Sizes
- 1⁄4" – 1" NPT
Applications
Tracing or drip applications with condensate discharge to atmosphere or to condensate return systems.
Operating principle
A series of bimetal discs senses the trap inlet temperature and pressure and controls the discharge temperature of condensate at around 50 °F (28 °C) below the saturation temperature of the inlet steam.
Design features
