Introduction
Thank you for purchasing the TLV thermostatic air vent for steam.
This product has been thoroughly inspected before being shipped from the
factory. When the air vent 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 air vent properly.
The air vent for steam is of a revolutionary design that uses a high-
performance X-element. This is a new type of valve mechanism in which a
thermoliquid is sealed inside the X-element and the valve opens or closes
based on the difference between the saturation temperatures of the
thermoliquid and the water. The X-element is very sensitive to changes in
temperature and responds with great accuracy, quickly discharging air and
the large quantities of condensate created immediately after operation start-
up, thereby greatly reducing start-up time. It also reacts with great sensitivity
to the hot air accumulated during operation, preventing air-locking.
The superior features of the X-element help increase heating efficiency and
reduce manpower requirements for maintenance and bypass blowdown.
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 for the models listed on the front cover. It is needed
not only for installation but for subsequent maintenance, disassembly
/reassembly and troubleshooting. Please keep it in a safe place for future
reference.
