Steam Traps

Steam traps are a critical part of any steam system. Their role is to automatically remove condensate, air, and other non-condensable gases from steam lines without allowing live steam to escape. This helps maintain system efficiency, reduce energy waste, and protect connected equipment from the problems caused by poor condensate drainage.

At Process Systems, we supply a broad range of steam traps in Australia for steam distribution, heat transfer, and process applications. Our range includes thermodynamic, float, and inverted bucket steam traps, along with related condensate management products such as drain separators, pump traps, pumping trap assist units, and steam trap checkers. 

With high-quality products, a huge range of stock on-hand and same-day dispatch on most in-stock items, we’ll help you find the right solution quickly.

Steam trap types for different applications

Different steam systems require different trap designs. That is why Process Systems offers a range built around the main steam trap operating principles.

Thermodynamic steam traps

Thermodynamic steam traps are compact, simple, and efficient. They operate using the velocity and thermodynamic properties of steam and condensate, typically with a hardened disc as the main moving part. These traps are well-suited to steam distribution systems and can handle demanding conditions such as superheat, water hammer, vibration, and corrosive condensate. We offer stainless steel and ductile iron thermodynamic steam traps, with BSPT threaded sizes from 1/2" to 1", pressure ratings up to 42 BAR, and temperature ratings up to 425°C, depending on model.

Float steam traps

Float steam traps are mechanical traps designed for continuous condensate discharge. They use a lever-and-float arrangement to respond to changing condensate levels, making them effective for both light and heavy condensate loads. This makes them a strong choice for process and heat transfer plant where efficient heat transfer matters. We stock ductile iron float steam traps in multiple sizes, including 1/2" to 2" BSPT, with pressure ratings up to 21 BAR and temperature ratings up to 220°C. A high-capacity 50 mm float steam trap is also available for larger duties.

Inverted bucket steam traps

Inverted bucket steam traps are another mechanical option. These models use the buoyancy of an inverted bucket connected to a lever mechanism that opens and closes the valve. They are known for reliability, excellent tolerance to water hammer, and suitability for higher-pressure duties when installed correctly. We stock a ductile iron inverted bucket steam trap with integral strainer in sizes from 1/2" to 1" BSPT, with a pressure range up to 16 BAR and temperature rating up to 220°C.

Drainage, pumping, and condensate management

Our extensive range includes products that support steam system performance beyond the trap itself. Ductile iron drain separators and flanged drain separators are available for condensate separation and drainage, with pressure ratings up to 20 BAR and temperatures up to 220°C.

For applications where condensate needs to be lifted or discharged under challenging conditions, we also offer a ductile iron pump trap and a float/pumping trap assist unit. These are suited to applications where gravity drainage alone is not enough and controlled condensate removal is required.

To support maintenance and testing, the range also includes a steam trap checker. This unit diagnoses float, bucket, thermostatic, and thermodynamic traps in as little as two to eight seconds, helping maintenance teams quickly assess trap operation.

Choosing the right steam trap

There is no universal steam trap. Choosing the right trap depends on the application, operating pressure, temperature, condensate load, back pressure, and the duty required. Mechanical traps may also require specific internals to match the system operating pressure or differential pressure.

Steam traps should always be installed in accordance with the manufacturer’s recommendations and good steam fitting practice. Direction of flow, orientation, access for maintenance, and discharge location all need to be considered. Returning hot condensate to the boiler is often recommended because it retains significant energy and is generally very clean, reducing both fuel use and chemical treatment requirements.

Service life depends on steam quality, operating conditions, and maintenance. Installing strainers is strongly recommended to reduce the amount of dirt and impurities reaching the trap internals. With correct sizing, proper installation, and regular inspection, a steam trap should perform for many years. Regular checks are important, as failed traps can lead to wasted energy, higher fuel bills, and lost production.
