BLU ZAC TTD – Thermodynamic Disc Steam Trap

The BLU ZAC TTD is a thermodynamic steam trap with a machined forged body, designed for condensate drainage in industrial steam lines. It operates with a free-floating disc: cold condensate opens the passage, while incoming steam increases flow velocity, creating conditions for disc closure. Discharge is intermittent, and the datasheet notes potential live steam loss, so selection should be based on actual Δp and backpressure.

Technical Specifications

Connections: BW per ANSI B16.25, flanges ANSI B16.5, SW per ANSI B16.11, NPT/BSP per ANSI B1.20.1 and ANSI BS21.
TTD48: ¼"–1", rating 600, max differential pressure 50 bar.
TTD49 / TTD50: up to 2½", rating 800, max differential pressure 50 bar.
TTD85: up to 3", rating 900, max differential pressure 85 bar.
TTD100: rating 1500, max differential pressure 100 bar.

Materials and Sealing

Available body materials include ASTM A105, A350 LF2, A182 F304/F316, F22, F91, F321, F347, F44, F51, and F53. The seat and disc are AISI 420, the strainer AISI 316, and gaskets are graphite with 316 spiral wound in serviceable seat/strainer versions.

Applications

Used in main steam lines, steam tracing, turbines, marine installations, and presses. No actuator required. For heat exchangers with continuous high flow or unacceptable condensate accumulation, consider a float trap.

Installation and Maintenance

Operates in any position, preferably horizontal. Maintenance includes isolation, body cleaning, disc/seat inspection, gasket replacement, and strainer cleaning or replacement where applicable. Restart gradually, checking for line leakage.

Description

The thermodynamic type of steam trap is created for standard applications, designed for standards customer’s requirements, it’s obtained from a machined forged billet.

Steam traps suitable for high pressures and capacities, usable for all applications.

How it works:

The disc is free and rests on the housing; in the steam trap there is no fluid of any kind.
Start-up: when the condensate begins to circulate, the disc is prevented from adhering to the housing, making the steam trap discharge the excess condensate.
As the system heats up, steam begins to arrive, traveling faster than the condensate due to the effect of Bernoulli’s principle; a reduction in pressure is generated inside the housing, forcing the disc to adhering to it and trapping the steam inside.
When the condensate arrives, the speed of flow will reduce, releasing the disc from the housing and allowing the steam trap to discharge the excess condensate.
