Mechanical steam traps

Mechanical traps operate on the density difference between condensate and steam, using condensate level changes to move the float and actuate the valve disc for steam sealing and condensate discharge. These traps feature low subcooling and are minimally affected by pressure and temperature variations. They discharge condensate promptly, helping to prevent accumulation in heating equipment and support efficient heat transfer, making them suitable for a wide range of production processes.

Hot-statical Force Steam Trap

Thermostatic steam traps typically consist of a valve body, bonnet, spring, piston, and sealing rings. They operate on the principle of thermal expansion and the characteristic that water expands more rapidly than steam at elevated temperatures. A compression spring is mounted on the bonnet, with its lower end connected to the piston and the upper end to the bonnet. When the water level in the working medium exceeds the set point, water enters the valve body, pushing the piston upward and compressing the spring to close the valve. When the water level drops below the set point, the spring force pushes the piston downward, opening the valve to discharge condensate.

Hot-motive Force Steam Trap

Thermodynamic steam traps operate on thermodynamic principles and are commonly used in steam heating systems, compressors, and similar equipment to discharge excess condensate. They are suitable for high‑temperature and high‑pressure applications, offering durability and operational flexibility. When water in the system is heated, its density decreases and vapor forms, creating pressure changes that the trap utilizes to open and release condensate. The trap typically consists of a control valve, a temperature sensor, and a discharge port; when a certain amount of condensate accumulates, the sensor detects the temperature change and actuates the valve to open, allowing automatic drainage.
