Features:
- The bi-metallic element and seat can be easily removed and replaced in minutes with the trap body still in-line.
- Excellent at discharging air, which allows steam to enter quickly; extremely important during start-up.
- Rugged stainless steel bi-metal element resists shock from water hammer.
- Freeze-proof when trap is installed in a vertical orientation allowing for complete condensate drainage.
- Hardened stainless steel seat for extended service life.
- Includes integral strainer with optional blowdown valve Standard factory-set sub cool is 25°F but is also field-adjustable .for optimum performance and energy savings.
Options & Features (See Specification Sheet For Full List):
BM300 Thermostatic Bi-Metal Steam Trap (Carbon Steel)
DRIP: The BM300 is a Medium Capacity Thermostatic Bimetal steam trap which is ideal as a drip trap on superheated steam mains and steam supply lines, as well as saturated steam lines and steam tracing applications. Bimetal traps subcool condensate before opening, making them extremely energy efficient and highly resistant to steam loss.
How It Works
This thermostatically-actuated trap contains a bi-metallic thermal element that expands when heated and contracts when cooled to 25°F (average) below saturated steam temperature. When air or sub-cooled condensate are present, the trap is in the open discharge position. When steam reaches the trap, the element expands and closes off tightly.
Installation & Maintenance
Trap can be installed in any orientation. Internal seating surfaces and bi-metal may be accessed for cleaning or repair, if needed, while the product remains in-line. Repair is done by removing the cover and replacing the thermal controller assembly.
Sample Specification
The steam trap shall be of thermostatic bi-metal type with forged carbon steel body, stainless steel thermal element, and integral strainer. Trap must be in-line repairable with a bolt-on cover. Seat and valve to be hardened stainless steel.
