automaticthermostaticbimetallic

Thermostatic steam traps How a bimetallic thermostatic steam trap works 1. On start-up, the bimetallic element is relaxed and the valve is open. Cooled condensate,plus air, is immediately discharged. 2. Hot condensate flowing through the trap heats the bimetallic element causing it to pullthe valve towards the seat. 3. As the hot condensate is discharged and approaches steamsaturation temperature the bimetallic element closes the valve.When there is no flow through the trap the condensatesurrounding the element cools causing it to relax and theupstream pressure opens the valve. Condensate is dischargedand the cycle repeats. Features and benefits: • Condensate is discharged at below steam saturation temperature, utilising sensible heat in the condensate and reducing flash steam losses • Automatically discharges air and other incondensable gases to aid rapid warm-up of plant • The bimetal elements can work over a wide range of steam pressures without any need for on-site adjustment • Resistant to waterhammer and freezing • The SMC32 series has a two bolt cover design for ease.
