Introduction
Thank you for purchasing the
Free Float 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.
This instruction manual is edited based on the JH-P Series (with cover plug). The
JH-W Series (with socket welded cover connection), JH-F Series (with flanged cover
connection) and JH-V Series (with manual air vent valve) are described at the end of
this manual in the 'Option’ section.
Both JH7RH-P and JH7RHT-P free float steam traps employ a hinge-less and lever-
less free float to rapidly, automatically and continuously discharge the inflowing
condensate that is continuously generated inside the equipment, thus preventing the
accumulation of condensate and thereby improving the heat transfer efficiency of the
equipment.
In particular, JH7RHT-P/JH7RHT-V (option) possess the highest heat resistance of
the TLV steam trap product range, and are of a specification that is suitable for use on
thermal power plant steam mains, which operate at increasingly high temperatures in
recent years.
This steam trap also employs a precision-ground float and three-point seating that
supports the float securely at three points and ensures a high degree of sealing
when even only minute quantities of condensate are present.
This free float steam trap is suitable for locations at which extremely small amounts
of condensate are generated, such as superheated and saturated steam mains and
branches, and for applications under long continuous operation with the introduction
of almost no air.
If detailed instructions for special order specifications or options not contained in this
manual are required, please contact
for full details.
This instruction manual is intended for use with the model(s) listed on the front cover.
It is necessary not only for installation but for subsequent maintenance,
disassembly/reassembly and troubleshooting. Please keep it in a safe place for
future reference.
