The SFT40AT Lever Float Steam Trap features a cast steel body and cover with all-stainless steel internals. Designed with wear allowances for extended durability, it includes a special channel design to prevent water hammer. The trap utilizes a patented flexible closing system and micron-level precision to prevent steam leakage. It is equipped with an integrated air vent to eliminate air binding and an independent filter for clean operation. A drain plug is provided at the bottom to prevent freezing by draining residual water during shutdown.
