Thermostatic Steam Trap

A thermostatic steam trap is an automatic condensate discharge valve that utilizes a temperature-sensing mechanism (such as a filled bellows, bi-metallic strip, or capsule) to automatically discharge sub-cooled condensate, air, and non-condensable gases from steam systems while preventing the escape of live steam. The trap operates based on the temperature difference between high-temperature steam and lower-temperature condensate; when cold condensate or air is present, the element contracts to open the discharge port, and as hot steam reaches the trap, the element expands to instantly seal the valve. Conforming to standards like ASME B16.34, EN 26704, and ISO 6948, these energy-efficient steam specialties are primary specifications in sterilizers, laundry presses, and steam heating coils, allowing HVAC contractors and steam utility engineers to maximize system thermal efficiency by importing certified thermostatic steam traps directly from specialized manufacturers in China via our advanced B2B commercial platform.
