Warning Use to switch the main valve. Push Type (Tool Required) SQ1000 SQ2000 Push down on the manual override button with a small screwdriver until it stops. Locking Type (Tool Required) Slide Locking Type (Manual Type) SQ1000 SQ2000 Push down completely on the manual override button with a small screwdriver. While down, turn clockwise 90° to lock it. Turn it counterclockwise to release it. SQ2000 The manual override is locked by sliding it all the way to the pilot valve side (ON side) with a small flat head screwdriver or finger. Slide it to the fitting side (OFF side) to release it. In addition, it can also be used as a push type by using a screwdriver, etc., of o2 or less. q w Bore o4 Bore o4.8 Bore o2 OFF position ON position (SQ2000 only) q w Bore o4 Bore o4.8 Manual Override Caution SQ1000 SQ2000 �� 4 Position Dual 3 Port Type (SQ1000/2000) �� 3 Position Type (SQ1000/2000) �� Double Type (SQ1000/2000) �� Single Solenoid Type (SQ1000/2000) Locked position Locked position Light/Surge Voltage Suppressor Indicator lights are all positioned on one side for both single solenoid and double solenoid types. For double, 3 position, and 4 position dual 3 port types, 2 colors are used to indicate the energization of A side or B side. Standard, High pressure type Quick response type Positive common spec. Negative common spec. Positive common spec. Negative common spec. Quick response type Standard, High pressure type Note) With quick response type, approximately -40 V of coil surge voltage is generated when the valve is switched OFF. Note) With quick response type, approximately -40 V of coil surge voltage is generated when the valve is switched OFF.

When the valve is continuously energized, use the standard type (0.4 W) at ambient temperature of 40°C or less with proper heat radiation. In particular, if three or more adjacent stations on the manifold are energized simultaneously for extended periods of time or if the valves on A side and B side of the dual 3 port valve are energized simultaneously for a long period of time, take special care as the temperature rise will be greater. 1450
