STAINLESS STEEL Inverted Bucket 3/4" Thermostatic Testing Steam Trap
steam trap are available in threaded and flanged types, with various sizes and pressure ratings. They are high-temperature and corrosion-resistant, offer sensitive opening and closing, and provide stable drainage, making them suitable for steam systems.
Working Principles
This steam trap utilizes the density difference between steam and condensate to achieve automatic opening and closing. During startup, condensate enters the valve body, the inverted bucket sinks, and the valve opens to discharge condensate and air. When steam enters, the inverted bucket rises due to buoyancy, closing the valve core to prevent steam leakage. A built-in temperature control element assists in venting at low temperatures, improving startup efficiency. The 3/4-inch interface facilitates installation, and the test configuration supports online testing of steam trap performance, making it suitable for stable, continuous steam system operation.
