SOLENOID VALVE
SVA20 Series
Solenoid Valve
Detailed Safety Instructions
Before using PISCO products, be sure to read "Safety Instructions" and "Safety Instruction
Manual" and "Common Safety Instructions for Solenoid Valve Series".
1. When a solenoid valve is operated under viblation less than 5G, install it so that a spool
valve is at a right angle to the vibrating direction.
*Refer to the figure of "4. Installation" under "Precautions for Use".
1. When the valves are used with Valve Manifold, back pressure can cause malfunctions
of the actuator (single acting cylinder, etc.) In such a case, provide a check valve to the
exhaust port.
2. Do not use a 3-position valve for accurate mid-stroke positioning of the cylinder.
Compressiveness of air may not allow accuracy in stop position. Also, the valve permits
leakage, so that the stop position may not remain constant for a long time
3. Do not give excessive tension or bending to the individual plug-in connector (Cable).
Disconnection or damage to the connector may be caused.
4. The Cartridge Fitting can be disconnected by removing the lock pin. However, make sure
that the lock pin is properly in place before using.
5. Read the manual carefully for proper installation and removal of valves. Also, keep the
manual at hand.
6. Read the method for replacing Cartridge Fitting in the catalog carefully.
7. Read the method for replacing Cartridge Fitting and piping ø8mm Compression Fitting in
the catalog carefully.
Safety Instructions for Vacuum-Operateble 2/3-Port Solenoid Valve
● Connect 2(B) Port with air supply port and 4(A) Port with an actuator port. The reverse connection
causes troubles.
● Place a filter to prevent foreign particles from etering inside.
Precautions for Dual Pressure Option
● Triangle Mark indicates the partition to
separate supply pressure. Refer to the
right figure. The intake air pressure of
the partitioned right side including the
traiangle marked-manifold block is suppled
from P2, and that of the partitioned left
side is supplied from P1.
(In the right figure, St.1 to 2 is P1 side,
and St.3 to 8 is on P2 side.)
● Air partition border can not be change its
position after shipment.
● Selectable Intake and Exhaust Port is
only "A" for Dual Pressure option.
