6.2 Warning and precaution on installation
WARNING
(1) The pressure reducing valve is heavy: check its weight by referring to the "3.
Dimensions and parts". Securely holding the valve with a lifting gear, attach and
connect it to the piping.
※ U nsteady valve may fall during assembly, causing bodily injury.
(2) If a primary pressure regulating valve or safety valve is installed to the outlet of the
pressure reducing valve, connect a blow-off pipe to the outlet of the regulating (safety)
valve to direct possible blowing fluid to a safety location.
I f the blowing fluid is hot, it will cause burn injury.
※
CAUTION
(1) Do not disassemble the pressure reducing valve unless it must be.
O nce incorrectly disassembled, the pressure reducing valve cannot function as it
※
should, after reassembling.
(2) Before connecting the pressure reducing valve to the piping, remove the foreign
materials from the piping.
I f foreign materials are introduced into the pressure reducing valve, it cannot operate
※
at the proper performance and may be damaged.
(3) Install a strainer (equivalent to 80 mesh) to the inlet of the pressure reducing valve.
I f foreign materials are introduced into the pressure reducing valve, it cannot operate
※
at the proper performance and may be damaged. (Refer to 6.1 Piping example, Fig.1.)
