Mechanical steam traps operate based on the difference in density between steam and condensate. These traps utilize a float or bucket mechanism, which responds to the presence of liquid water. As condensate accumulates, the float or bucket rises (or lowers in the case of an inverted bucket), opening a valve to discharge the collected water. This process is repeated continuously, ensuring efficient removal of condensate and preventing steam loss.
In essence, the volumetric displacement of the float or bucket directly controls the valve opening. The float’s position, dictated by the rising water level, dictates the flow rate and response time of the trap. This mechanism offers reliable performance and efficient operation.

Specifications of Mechanical Steam Trap
| Trap Type | Float Trap, Inverted Bucket Trap |
| Operating Principle | Volumetric: Uses a float or inverted bucket to sense condensate level and control valve opening/closing. |
| Materials | Body: Cast Iron, Cast Steel, Stainless Steel; Internal Parts: Stainless Steel, hardened stainless steel, etc. |
| Connections | Threaded (NPT, BSPT), Flanged (ANSI, DIN), Welded |
| Pressure Rating (Maximum) | Up to 46 bar (670 psi) or higher, depending on the model. Higher pressures are common in float traps. |
| Pressure Rating (Minimum) | Can operate at very low pressures (close to atmospheric) - this is a key advantage. |
| Temperature Range | Up to 260°C (500°F) or higher, depending on the model. |
| Capacity (Condensate Discharge) | Varies widely. From a few kg/hr to tens of tons/hr, depending on the trap size and pressure differential. |
| Air Venting | Excellent. Automatic air venting is a key characteristic of float traps. Inverted bucket traps vent air as well. |
| Steam Loss | Low, particularly with well-maintained traps. |
| Freeze Protection | Some models are designed with freeze protection features (e.g., with internal steam chambers to keep the condensate hot). |
| Installation | Horizontal or vertical installation (depending on the model), often with a strainer upstream. |
| Maintenance | Relatively easy maintenance, including periodic inspection and cleaning or, in some cases, replacement of internal parts. |
| Size Range | ½" to 4" or larger (connection size). |
| Body Design | Straight-through or angle patterns. |
| Differential Pressure | Up to high delta P ratings, depending on application. |
| Fail-Safe | Closed or open fail-safe mode, depending on the manufacturer and design. |
