The working principle of a steam trap relies on steam entering a valve filled with water; this creates buoyancy within the inverted tank. The buoyancy, being greater than the weight of the tank, causes it to rise, which in turn moves a lever that closes the steam trap. Since the barrel is open, changes in system pressure equalize the pressure inside and outside it, allowing it to withstand water hammer. All wear-prone parts have been specially designed for long-term use. This valve is an energy-saving masterpiece that combines environmental protection, energy savings, and water conservation, and is widely used in industries such as food processing, papermaking, petrochemicals, textiles, and printing and dyeing. By taking advantage of the valve’s excellent high backpressure rating and ultra-low leakage properties, pump-free backpressure recovery of high-temperature condensate can be achieved, delivering significant economic benefits to enterprises.
