Correct Usage of the
COSPECT
Pressure Reducing Valve
Install properly and DO NOT use this product outside the recommended
operating pressure, temperature and other specification ranges.
Improper use may result in such hazards as damage to the product or
malfunctions which may lead to serious accidents. Local regulations
may restrict the use of this product to below the conditions quoted.
CAUTION
1. The
COSPECT
should be operated only within its specifications.
2. Installing an ON / OFF Valve (Solenoid Valve or Motorized Valve)

If an on-off valve, such as a motorized valve, is required, install it at the inlet side
of the
COSPECT
. If a solenoid valve is installed at the outlet of the reducing
valve, its opening and closing will cause heavy chattering and may lead to
damage of the piston and main valve. (When the on-off valve opens, the
secondary pressure of the reducing valve changes from zero to the set pressure.
Passing through an area of the reducing ratio of less than 10:1, where
adjustment is impossible, chattering occurs momentarily.)
3. Installing a Safety Valve

When installing a safety valve to protect the air equipment, be sure to install it on
the air equipment or directly before the inlet of the air equipment. If the safety
valve is installed on the outlet side of the
COSPECT
between the
COSPECT
and
a control valve, an eventual pressure rise could activate the safety valve.
