BLU ZAC TSB25 – Thermostatic Bimetallic Steam Trap

The BLU ZAC TSB25 is a thermostatic steam trap with a bimetallic element, crafted from precision-machined forged material. It is designed for standard industrial steam applications where condensate discharge with thermostatic delay and metallic control mechanism is acceptable.

Operating Principle

At startup, the mechanism remains open to expel air and cold condensate. As temperature rises and steam approaches, the bimetallic discs flex, moving the valve towards the seat. When new condensate accumulates, the mechanism cools and reopens the flow path.

Technical Specifications

Sizes: 1/4" to 2 1/2".
Rating: 600.
Maximum differential operating pressure: 25 bar.
Minimum differential operating pressure: 0.3 bar.
Maximum backpressure: 80% of upstream pressure.
Suitable for superheated steam, freezing conditions, and water hammer.
Discharge only in the presence of condensate, with modulating operation.

Materials and Connections

Bodies available in ASTM A105, A350 LF2, A182 F304/F316/F304L/F316L, F11, F22, F91, F321, F347, F44, F51, and F53, depending on pressure, temperature, and media compatibility. Seat is AISI 420, filter AISI 316, and gaskets are graphite with 316 winding. Connections: BW per ANSI B16.25, flanges ANSI B16.5, SW per ANSI B16.11, NPT, BSP, ANSI B1.20.1, and ANSI BS21.

Applications

Main steam lines,
steam tracing,
turbines,
marine installations,
presses and heated equipment.

Selection is based on condensate load, Δp, backpressure, temperature, body material, and connection type. For exchangers where condensate backing-up is not allowed, a float trap is considered.

Maintenance

Operable in any position, preferably horizontal. Maintenance involves line isolation, cover removal, body cleaning, seat and gasket replacement. The integrated filter is cleaned or replaced via the plug.

Description

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

How it works:

The bimetallic pack inside the capsule attached to the housing is raised.
Start-up: when the condensate begins to circulate, the bimetal is prevented from reacting to the low temperature, keeping the shutter in the open position.
As the system heats up, the condensate reduces and steam begins to arrive, heating the bimetal, which reacts by bending. The combined force generated by the pack of bimetallic discs creates a movement on the shutter, lifting it until it comes into contact with the housing.
As the condensate accumulates, the bimetal cools, contracting and releasing the shutter, which in turn frees the flow.
