How do Bimetallic Steam Traps work?
Bimetallic steam traps operate by using two bonded metal strips that expand and contract at different rates as temperature changes.
When cooler condensate enters the trap, the bimetallic element relaxes and opens the valve, allowing the condensate to discharge.
As the temperature rises toward steam level, the element bends and closes the valve tightly, preventing live steam from escaping.
Unlike other thermostatic designs, bimetallic steam traps are engineered to hold condensate until it is sub-cooled, releasing it only once useful sensible heat has been extracted. This controlled discharge makes them highly energy efficient in applications such as tracing lines and low-load systems, where retaining heat in the condensate improves overall system performance.
Built for strength, bimetallic steam traps are the most robust of all thermostatic designs.
Their solid construction allows them to withstand water hammer, vibration, and corrosive condensate without loss of performance. This durability protects plant equipment from damage caused by condensate build-up and thermal shock, while ensuring reliable long-term operation in harsh industrial environments.
By combining energy conservation with mechanical resilience, bimetallic steam traps deliver dependable condensate control where both efficiency and toughness are essential.
