TD600

TD600 Thermodynamic Steam Trap

DRIP, TRACING: The TD600 is Non-Repairable and commonly used as a drip trap on steam mains and steam supply lines. Ideal for outdoor applications that are subject to freezing and for super heated steam conditions.

The TD600L is Reduced Size Discharge Orifice holes which are preferable in terms of performance, longevity, and efficiency; particularly on pressure over 150 psi

Product Overview
DRIP, TRACING: TD600 model steam traps are most commonly used in drip applications, such as draining condensate from steam mains and steam supply lines. They can also be used for steam tracing applications. These traps are suitable for outdoor applications that are subject to freezing as well as superheated steam conditions. They are compact and rugged with only a single moving part. If a trap with an integral strainer is desired, the TD600S is recommended. If a fully in-line repairable design is required, the TD700S or the UTD450 with Universal QuickChange connector is recommended.
Features
• High pressure applications up to 600 PSIG
• Hardened stainless steel seat and disc for extended service life even at high pressure
• Single trap will operate over the entire pressure range of 3.5-600 PSIG (recommended above 30 PSIG)
• Suitable for superheated steam
• Freeze-proof when trap is piped in a vertical orientation for complete drainage of condensate
• Three-hole balanced discharge extends life of the seat area
• Trap will function in any orientation (horizontal preferred)
How It Works
The disc is the only moving part inside a thermodynamic trap. When steam enters the trap, it creates an internal pressure above the disc that instantly forces the disc to close tightly on the seat, preventing the steam from escaping. The internal steam pressure (holding the disc and seat shut) eventually drops, and the trap re-opens. When condensate enters the trap, it pushes the disc upwards, allowing the condensate to freely discharge. If steam is present, the trap instantly shuts.
Selection / Sizing / Capacities

The TD600L has reduced size discharge orifice holes which are preferable in terms of performance, longevity, and efficiency; particularly on pressures over 150 psi. For most drip applications the 1/2” TD600Lshould have sufficient capacity. For higher load drip applications or if a 3/4” pipe connection is required, use 3/4” TD600Lfor best results. Choosing a model with a condensate handling capacity in the range of the specific application will prolong trap life.

L = Reduced Size Discharge Orifice holes which are preferable in terms of performance, longevity, and efficiency; particularly on pressures over 150 psi.

Example:
Select working pressure; follow column down to correct capacity (lbs/hr) block. 
Application: 500 lbs/hr at 100 PSIG working inlet pressure
Size/Model: 3/4” TD600L-13-N

Notes:    1) Maximum back pressure not to exceed 80% of inlet pressure (measured in absolute pressure) or trap may not close.
 2) For optimum performance, recommended for operating pressure above 30 PSIG.
Dimension and Weights

Options
An insulation cap is available to reduce cycle rates and steam loss in rain, snow, or cold environments.
Installation and Maintenance
The TD600 can be installed in any orientation; however, horizontal with cap facing upward is preferred for longest service life. The one piece Body-Seat design is extremely simple and economical; however, this configuration is generally considered non-repairable since the seat cannot be repaired if damaged or worn. Welding of trap body directly into pipeline is not recommended since excessive heat may cause distortion of the seat area. The TD600 does not contain an integral strainer and separate strainer should therefore be installed to protect from dirt and pipe scale. If a fully in-line repairable design or a trap that can be welded into pipeline is desired, the TD700S, TD900S or the UTD450 with Universal Quick-Change connector is recommended.
Sample Specification
The steam trap shall be a thermodynamic disc type with all stainless steel construction. Integral seat design and disc to be hardened for long service life. Unit shall be capable of installation in any orientation and self-draining when mounted vertically.
