Introduction 

 

Thank you for purchasing the TLV float dynamic steam trap. 

This product has been thoroughly inspected before being shipped from the 
factory. When the product is delivered, before doing anything else, check the

ordinary. Also be sure to read this manual carefully before use and follow the 
instructions to be sure of using the product properly. 

This steam trap is designed to automatically discharge condensate from the 
steam space. This trap is ideal for use on heaters or dryers or other steam 
equipment on applications where large quantities of condensate are 
generated. 

If detailed instructions for special order specifications or options not contained
