Warning
① Do not use in an atmosphere having corrosive gases, chemicals, sea water, water, water steam,
or where there is direct contact with any of these.
② Do not operate in locations where vibration or impact occurs.
③ In locations which receive direct sunlight, provide a protective cover, etc.
④ In locations near heat sources, block off any radiated heat.
⑤ In locations where there is contact with spatter from water, oil or solder, etc., implement suitable
protective measures.
Caution
① Do not use a precision regulator outside the range of its specifications as this can cause failure.
(Refer to the specifications.)
② When mounting is performed, make connections while confirming port indications.
③ When mounting the bracket or tightening the hexagon panel nut on the panel, tighten them to the
recommended proper torque.
Looseness or faulty sealing will occur if tightening torque is insufficient, while thread damage will result if
the torque is excessive.
Recommended Proper Torque [N
Set nut (for bracket)
Hexagon panel net (for knob type only)
④ After pressure adjustment, be sure to tighten the lock nut. When tightening the nut, tighten so
that the knob does not move due to friction caused by tightening.
⑤ When pressure is applied to the inlet of a regulator, make sure that the output is connected to the
circuit. Air blow occurs from the outlet and it depends on the operating conditions.
⑥ The set pressure may vary depending on the elapsed time and change in ambient temperature
after pressure setting. If the setting value varies, adjust with the knob.
⑦ If the directional control valve (solenoid valve, mechanical valve etc.) is mounted and ON-OFF is
repeated for a long time, the set pressure may vary. If the setting value varies, adjust with the
knob.
⑧ There may be pulsation or noise depending on the pressure conditions, piping conditions and
ambient environment. In this case, it is possible to improve the problem by changing the
pressure conditions and piping conditions.
If the problem is not improved, contact your SMC sales representative.
⑨ There is no connection thread on the exhaust port. If it is necessary to mount a silencer to the
exhaust port, please contact your SMC sales representative.
⑩ When installing a pressure gauge to the product, do not apply pressure more than the maximum
display pressure. This will cause a malfunction.
⑪ When using a precision regulator between a solenoid valve and cylinder, caution should be taken
regarding the following points.
· The residual pressure of the cylinder will be exhausted from the regulator's exhaust port. (Depending
on the conditions, partial backflow may occur.)
· When holding pressure at the intermediate position of a closed center solenoid valve, due to reduced
pilot pressure the pressure inside the cylinder will not be able to be held because the regulator will
perform an exhaust operation. If it is necessary for the pressure inside the cylinder to be held, please
consider using in combination with a separate shut-off valve.
· When releasing pressure at the intermediate position of an exhaust center solenoid valve, depending
on the conditions, vacuum pressure may remain inside the cylinder. If the introduction of atmospheric
pressure is required, please consider using in combination with a separate atmospheric pressure
introduction valve.
