Why choose a disc trap?

Disc traps are valued for their compact size, versatility, and wide pressure range, but have you ever wondered how to improve their overall performance and extend their service life?

Why choose TLV?

The TLV PowerDyne™ series is designed to reduce Life Cycle Cost. This includes multiple factors such as reduced costs related to purchasing, installation, maintenance, and steam loss.

Four reasons to choose PowerDyne™

1) Long Service Life

Disc traps can be susceptible to dirt, environmental conditions and no-load actuation, causing chattering which accelerates wear and shortens service life. Not only do the PowerDyne™ disc traps include a built-in Y-strainer to filter dirt, but they are also equipped with a mirror-polished lapped disc, which provides tight sealing even under severe superheat conditions. This minimizes chattering and prolongs service life.
 

2) Easy Maintenance

When disc traps fail, a common practice is to replace the entire trap, not just the internals. Short service life results in high replacement costs. TLV PowerDyne™ disc traps have been engineered to save time and minimize maintenance costs. The replacement module design enables quick and easy inline repair of normal wear parts without having to replace the entire trap.
 

3) Energy Conservation

In order to prevent air binding, some valve discs have a rough-ground surface or machined leakage path. These actions reduce sealing, increase steam loss, and can eventually lead to a costly blowing condition. The TLV PowerDyne™ series includes an air jacket for resistance to environmental conditions. The hardened valve trim also helps reduce wear and promotes reliable operation, effectively minimizing steam loss.
 

4) Increased Productivity

Disc traps are prone to air binding, which prolongs start-up time by preventing the discharge of condensate. In PowerDyne™ disc traps, initial air is automatically discharged by the thermostatic air venting design*, significantly reducing start-up time.

Air Jacket

In traps with a single-layer cap, adverse weather conditions and radiant heat loss can result in steam loss from rapid-cycling actuation. The TLV PowerDyne™ series is equipped with an air-insulated jacket, giving resistance to environmental effects and minimizing unnecessary operation and steam loss.

Mirror-polished Sealing Surfaces

Some valve discs include an air leak pathway or rough finish to prevent air binding. However, this can result in greater surface wear and steam leakage due to no-load actuation. The TLV PowerDyne™ series solves this problem: the bimetal air vent ring* eliminates air binding and allows the hardened sealing surfaces to be mirror polished, resulting in a tight seal that saves steam.

Bimetal Air Vent Ring*

To reach full operating efficiency, initial air and cold condensate must be purged from steam lines quickly. PowerDyne™'s bimetal air vent ring* quickly and efficiently vents start-up air without binding, eliminating the need for manual blowdown.

Replaceable Module

The replaceable module enables quick inline repair of normal wear parts, such as the valve seat and valve disc.

Strainer

TLV PowerDyne™ series disc traps include a built-in Y-strainer to filter dirt and scale, which helps protect the internal parts and limits wear.
