Spirax Sarco BTM7 Balanced Pressure Thermostatic Clean Steam Traps

Spirax Sarco BTM7 Balanced Pressure Thermostatic Clean Steam Traps are maintainable thermostatic steam traps designed to remove condensate from clean steam systems with minimal backing up. Their performance is influenced by surrounding steam pressure, and it is controlled by the concentration of the liquid mixture within its capsule whose boiling point is below that of water. At start-up, when conditions are cold, the capsule remains relaxed and the valve is fully open, allowing unrestricted discharge of air. As condensate flows through the trap, it heats up the capsule. The liquid inside then vaporizes before steam reaches the trap, building vapor pressure that expands the capsule and closes the valve. When heat is lost, the vapor condenses, the capsule contracts, and the valve reopens to release condensate. As steam approaches, the cycle repeats.
