BM300 Repairable Cast Iron Steam Traps

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.

The Body is made from Carbon Steel and trap internals are fully repairable while the product remains in-line. Repair is done by removing the cover and replacing the seat and thermal element. Contains an extremely strong and robust bimetal element which is highly resistant to waterhammer. The hardened plug is back-seated to function as an internal check valve. Standard subcool is 18°F but is also field-adjustable.
