The operating mechanism of bimetallic steam trap is a bimetallic strip which expands/contracts to control the trap opening. The rugged nature of bimetallic strip and lack of any other moving components make this trap highly suitable for high temperature and high pressure applications.
FMBM comes with an inbuilt check valve, strainer screen and an external adjustment screw for adjusting the discharge temperature of the condensate.
