Set the regulator while verifying the displayed values of the inlet and outlet pressure gauges. Turning the knob excessively can cause damage to the internal parts. 2. The pressure gauge included with regulators for.2 to MPa setting is for up to MPa use only. xceeding MPa of pressure can damage the gauge. evertheless, the gauge for the R regulator with.2 to MPa setting is for up to.mpa use. 3. Do not use tools on the pressure regulator knob as this may cause damage. It must be operated manually. Caution. e sure to unlock the knob before adjusting the pressure and lock it after setting the pressure. ailure to follow this procedure can cause damage to the knob and the outlet pressure may fluctuate. Pull the pressure regulator knob to unlock. (You can visually verify this with the "orange mark" that appears in the gap.) Push the pressure regulator knob to lock.

Do not use tools on the pressure regulator knob as this may cause damage. It must be operated manually.

When the inlet pressure (P) is shut off and released, the check valve w opens and the pressure in the diaphragm chamber q is released into the inlet side (igure 2). This lowers the pressure in the diaphragm chamber q and the force generated by the pressure regulator spring e lifts the diaphragm. Valve r opens through the stem, and the outlet pressure is released to the inlet side (igure 3). Pull the pressure regulator knob to unlock. (You can visually verify this with the "orange mark" that appears in the gap.) Push the pressure regulator knob to lock. When the knob is not easily locked, turn it left and right a little and then push it (when the knob is locked, the "orange mark", i.e., the gap will disappear). 2. knob cover is available to prevent careless operation of the knob. Refer to eatures for details. Maintenance Warning. When using the regulator between a solenoid valve and an actuator, check the pressure gauge periodically. Sudden pressure fluctuations may shorten the durability of the pressure gauge. digital pressure gauge is recommended for such situation or as deemed necessary. 44
