Introduction
Thank you for purchasing the
bypass blow valve.
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
bypass blow valve has excellent durability and reliable sealing
performance in addition to a structure which can clean its seating surfaces in a
simple operation. In support of this long-life product, the main components of the
valve are replaceable.
In conventional valves, when dust or scale adheres to the seating surface of the
valve seat section, leakage occurs eventually leading to erosion, and ultimately the
valve will no longer function properly.
This bypass blow valve utilizes a special material for the valve stem and valve seat
sections and together with its unique form, rotational contact between the seating
surfaces scrapes off scale and restores the sealing performance of the valve.
The proven special material, combined with the unique cleaning mechanism reduces
the burden of valve maintenance and operation.
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.
