The bellows type steam Trap uses a fluid-filled element (bellows) that operates under the principle of expansion and contraction. The fluid vaporizes and expands as the temperature increases, causing the bellows to close the valve. As the temperature decreases, the fluid condenses and contracts, causing the bellows to open the valve. These traps provide excellent air handling capability and are used for drip, non-critical tracing and process applications. The main advantage of the element is that on start-up loads, the trap is in the open position, allowing air and condensate to be rapidly removed from the system. Element traps offer wide operating pressure ranges, rugged welded stainless steel bellows, and various orifice sizes, making them a great choice for a majority of applications.
