Spirax-Sarco 59314C Disc Trap

The Spirax-Sarco 59314C (Model TD52L) is a high-performance 3/4" NPT thermo-dynamic steam trap engineered for reliable condensate removal in demanding industrial environments. Constructed with a rugged stainless steel body and featuring an electroless nickel plated finish, this disc trap is designed to withstand superheated steam and severe water hammer conditions. The low-capacity design makes it an ideal solution for steam main drainage, tracer lines, and process equipment in laundry or kitchen applications. Rated for a maximum operating pressure of 600 psig and temperatures up to 800°F, the TD52L ensures efficient intermittent discharge of condensate near steam temperature, keeping lines dry and maintaining optimal heat transfer. Its integral insulating cap provides significant performance stability in outdoor installations subject to freezing, while the hardened stainless steel disc ensures a prolonged service life by resisting erosion during high-velocity discharge cycles.

• Corrosion Resistance: All-stainless steel construction with a hardened disc and seating surface resists chemical attack and wire-drawing.
• High-Pressure Ready: Robust 600 psi rating allows for versatile deployment across high-pressure steam systems.
• Minimal Maintenance: The inline horizontal configuration allows for disc inspection and replacement without disturbing the existing pipework.
• Versatile Mounting: While horizontal mounting is preferred, the unit can be installed vertically for freeze protection when discharging downward.
• Operational Reliability: Unaffected by back pressure up to 80% of inlet pressure, preventing trap failure in complex return systems.

What is the difference between the TD52 and the TD52L?
The "L" designation indicates a low-capacity version. For example, a 3/4" TD52L provides the condensate handling capacity typically found in a standard 1/2" TD52, making it ideal for systems requiring a larger pipe connection with lower condensate loads.

Can this trap be used in superheated steam applications?
Yes, the thermodynamic disc design is inherently suited for superheated steam and high-temperature environments where other trap types might fail.

Does it require a separate strainer?
To protect the precision-lapped seating surfaces, it is highly recommended to install a 20-mesh strainer upstream, as this model does not feature an internal screen.
