Introduction
Thank you for purchasing the TLV electro-pneumatic control valve with built-in
separator and 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
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.
The TLV electro-pneumatic control valve with built-in separator and steam
trap is a revolutionary product that combines a digital positioner, a diaphragm-
type actuator, a separator and a steam trap. Steam-using equipment can
achieve its intended efficiency only if the steam being used is very dry. Using
steam in which matter such as condensate, scale or types of grease is
entrained can not only result in problems with the steam-using equipment and
in lowered productivity, but can also lead to shortened service life for and
malfunction of the control valve. The CV-COS-16 is a new control valve that
offers a solution for these problems by supplying high-quality steam to the
process and offering maximum productivity.
If detailed instructions for special order specifications or options not contained
in this manual are required, please contact TLV for full details.
This instruction manual is intended for use with the model(s) listed on the
front cover. It is needed not only for installation, but also for subsequent
maintenance, disassembly/reassembly and troubleshooting. Please keep it in
a safe place for future reference.
For details of the actuator and the electro-pneumatic digital positioner, refer to
the respective instruction manuals issued by the manufacturer.
