■
Corrosive environments
Do not use this product in an atmosphere
containing corrosive gases such as sulfur dioxide.
■
Ambient/fluid temperatures
Use at ambient/fluid temperatures within the
specified range of 0 to 50°C.
Even if the temperature is within the specified
range, do not use in a location where the ambient
temperature and fluid temperature could suddenly
change and cause condensation.
■
Guaranteed proof pressure/working pressure
differential
Usage in applications exceeding the proof pressure
or outside the working pressure differential could
result in failure. Use only within the specified range.
If the source pressure is low or the pressure at the
secondary side is high, the differential pressure
decreases and the fluid does not flow.
■
Drip-proof environment
The degree of protection of this product is
equivalent to IP40. Do not install this product where
water, salt, dust, or swarf is present or in a
pressurized or depressurized environment. The
product cannot be used with large temperature
variations or high temperature/humidity since
condensation may occur inside the body.
■
The solenoid proportional valve inside this product
does not have a fully closed function.
When a fully closed state is required, separately
provide a cutoff valve outside the product.
When the external cutoff valve is closed, keep the
product valve in standby at a fully closed state
(setting flow rate zero). If the product is left in the
normal control state with the external cutoff valve
closed, excessive flow is produced for a moment
when the external cutoff valve is opened.
When using with frequent ON/OFF operations, its
service life as a proportional valve may be reduced
depending on the working conditions.
■
Do not install this product in movable sections or
where it will be subject to vibration. Vibration or
impact may lead to malfunction.
WARNING
2. Working environment
Design/selection
■
Be alert for pressure loss in the piping.
When piping to this product, keep the differential
pressure between upstream and downstream sides
within the working pressure differential range (refer
to pages 2 and 4). Using the product outside the
working pressure differential range can inhibit
normal use.
In particular, an orifice or restriction in the
secondary side (downstream side) of the product
could cause incorrect operation. Please be careful.
In addition, the pressure on the primary side or
secondary side of the product may fluctuate
repeatedly, or the product control may not be able
to track pressure changes, leading to unstable flow
rate control.
■
Working conditions for CE compliance
This product is CE-marked, indicating conformity
with the EMC Directives.
EN61000-6-2; regulation matched to immunity
applies to this product. Conditions below are
necessary to comply with these standards.
Conditions
●
The evaluation of this product is performed by
using a cable that has a power supply line and a
signal line paired to assess the product's
performance.
●
This product is not equipped with surge
protection. Implement surge protection measures
on the system side.
CAUTION
■
This product's flow rate is measured at a mass flow
rate unaffected by temperature or pressure. The
unit is L/min, but this is the display when the mass
flow rate is converted to volumetric flow rate at
20°C 1 atmosphere (101 kPa) relative humidity
65%.
