Diaphragm-type steam trap "DL1 model"
Compact and leak-free! A highly capable trap with a free installation position.
The diaphragm-type steam trap is a trap that utilizes the temperature difference between the steam and condensate flowing into the trap to open and close the valve. 【Features】 1. All stainless steel with excellent corrosion resistance! All parts are made of stainless steel! It can be used in food equipment and other applications where corrosion resistance is a priority. 2. Minimal steam leakage! The temperature at which the thermal element opens and closes the valve is always lower than the saturation temperature, making it an energy-saving design that is less prone to steam leakage. 3. Compact design! With a face-to-face distance of 60 mm, it can be installed vertically or horizontally, making it easy to install even in small spaces!
