Thermodynamic disc steam trap

Performance/Advantages

Features a rational design, compact size, lightweight construction, and easy installation. It is resistant to freezing, water hammer, and overheating. Equipped with a stainless steel strainer, it offers convenient maintenance, responsive operation, excellent sealing performance, and a long service life.

Operating Principle

Disc-type steam traps utilize the thermodynamic differences in flow velocity and volume—which occur as steam and condensate pass through the valve orifice—to actuate the disc, thereby opening or closing the valve seat to discharge condensate while retaining steam.

Applications

Suitable for draining condensate while retaining steam in high-temperature steam main lines and superheated steam piping networks.

Key Selection Criteria

Condensate load (discharge capacity) in kg/h (apply a safety factor of 2–3x)
Maximum operating pressure
Operating pressure differential
Valve body material and nominal pressure
Connection type and dimensions

Operation and Maintenance

Verify that the valve body material, pressure rating, and temperature limits meet the requirements of the specific operating conditions.
Clean the piping thoroughly to remove debris before installation.
Install the unit as close to the heating equipment as possible.
Mount horizontally at the lowest point of the piping, ensuring the flow direction aligns with the marking on the valve body.
Install a dedicated steam trap for each piece of heating equipment to prevent mutual interference.
To ensure system stability, open the valve upstream of the steam trap slowly, allowing the unit to warm up gradually to its normal operating state.
Perform regular maintenance to ensure the steam trap continues to function correctly.
