Introduction
Thank you for purchasing the TLV pressure reducing valve for air, A-COS.
This product has been thoroughly inspected before being shipped from the
factory. When the product is delivered, before doing anything else, check the
specifications and external appearance to make sure nothing is out of the
ordinary. Also be sure to read this manual carefully before use and follow the
instructions to be sure of using the product properly.
Using air in which matter such as condensate, scale or types of oil is
entrained can not only result in problems with the air-using equipment and in
lowered productivity, but can also lead to shortened service life for and
malfunction of the reducing valves.
The TLV pressure reducing valve for air, model A-COS, is a new reducing
valve that eliminates these problems and makes possible the supply of high-
quality air at a constant pressure.
