Electrical power needed to drive a circuit.
Large flow type with power saving circuit
Power consumption is decreased by 1/3 reducing the wattage required to hold
the valve in an energized state.
After a maximum of 25 msec after applying current, the power saving circuit
starts to operate and power is reduced.
?Internal pilot (Standard)
Allows supply pressure to run through the inside of a solenoid valve to act on pilot valve.
?External pilot
Separating from supply pressure, the another pressure for pilot valve is obtained from external. Used when the main pressure is less than the minimum operating pressure or vacuum application.
?Direct operated
Drives the main valve by acting force of a solenoid.
Rubber seal
Air leakage is small because it has the spool valve with seal to slide.
Metal seal
Long service life because the metal spool slides.
?Direct ported
Port is available on the valve body
for piping directly.
?Base mounted
No port is available on the valve body.
Used with the manifold base or
sub-plate. Easy maintenance.
?Cassette type (SMC original)
Air passage of the valve body is
connected directly and mounted on
DIN rail. (No single unit is available.)
Baseless and low profile.
In maintenace or changing specifications, the pilot valve which switches the main valve is replaceable.
When piping specification is needed to change, fittings for A, B port are replaceable.
?Plug-in
Insert a valve into connector in the base side to integrate the wiring parts. Easy maintenance.
?Individual wiring (Non-plug in)
Electrical wiring is all done in the valve side.
Valve exhaust released from the same base cannot be returned to the cylinder ports.
Prevention of malfunction of a cylinder by back pressure.
? Standard: 300 mm, 600 mm
? Option: 1000 mm, 1500 mm, 2000 mm 2500 mm, 3000 mm, 5000 mm
2 pcs of 3 port valve are integrated in one body. If used as a 3 port valve, half the number of stations are only needed, compared with the conventional model and ideal for space saving.
Endurance was tested under SMC condition. Number of service life of solenoid valve is based on our test results and no guarantee is assured for everything.
No particle generation because external leakage is zero. After blowing the external surface, double packaging to shut out the dust.
Exhaust of main valve and pilot valve are common exhaust and released to the outside of clean room.
Each series is suited to"Grade1".
Copper and halogen-based materials are not used.
Grease: Lithium soap-based grease
Copper and halogen and silicon-based materials are not used.
No dust generation because of zero external leakage.
Grease: Lithium soap-based grease
The intrinsic safety type is Series 51-SY.
Products that can be used in an explosive atmosphere.
Depending on an atmospheric level, specifications are different.
Using rubber material (H-NBR or FKM) resistant for ozone in the compressed air.
Enclosure for the electrical equipment against an external solid foreign object or water ingress.
?Enclosure
IEC (International Electrical Committee) standards (IEC60529) define the protection degree against the
ingress of a solid foreign object as the 1st characteristics and against the ingress of water as the 2nd
characteristics. With both of these characteristics, IP number is defined to show the protection degree.
IP20: Protection against fingers entering the enclosure but not specifically against water.
IP65: Protection against dust entering the enclosure and not greatly affected by jets of water from all directions.
IP67: Protection against dust entering the enclosure and immersion in water at a specific pressure and time.
