Construction

The TLV A3N Disc Steam Trap consists of the following main components:

Stainless steel body
Thermodynamic disc
Cover
Built-in strainer
Valve seat
Sealing gasket

Its compact design with few moving parts ensures long service life and low maintenance costs.

Operating Principle

When condensate enters the steam trap, its pressure lifts the disc, allowing condensate to be discharged.

As live steam reaches the trap, the high steam velocity creates a pressure differential above and below the disc, forcing it tightly against the valve seat to prevent steam loss.

This opening and closing cycle occurs automatically based on thermodynamic pressure changes, requiring no external power or pneumatic control.

Features and Benefits

Excellent Energy Saving

Prevents unnecessary live steam loss, reducing fuel consumption and operating costs.

High Durability

Constructed from stainless steel for superior corrosion resistance and long service life.

Compact Design

Small and lightweight, making installation easy even in confined spaces.

Suitable for High Pressure Applications

Reliable performance in demanding industrial steam systems.

Fully Automatic Operation

No manual adjustment or external control is required.

Easy Maintenance

Simple internal construction minimizes maintenance requirements.

Applications

The TLV A3N Disc Steam Trap is commonly installed in:

Steam distribution pipelines
Pressure reducing stations
Heat exchangers
Unit heaters
Steam dryers
Outdoor steam lines
