Safety Instructions

These safety instructions are intended to prevent a hazardous
situation and/or equipment damage.These instructions indicate the
level of potential hazard by label of “Caution”,“Warning” or
“Danger”.To ensure safety, be sure to observe ISO4414

(Note1)

, JIS B

8370

(Note2)

and other safety practices.
Note 1: ISO 4414: Pneumatic fluid power – Recommendations for the
application of equipment to transmission and control systems.
Note 2: JIS B 8370: Pneumatic system axiom.

CAUTION : Operator error could result in injury or

equipment damage.

WARNING: Operator error could result in serious

injury or loss of life.

DANGER : In extreme conditions, there is a

possible result of serious injury or loss of life.

WARNING

1. The compatibility of pneumatic equipment is the

responsibility of the person who designs the pneumatic
system or decides its specifications.

Since the products specified here are used in various operating
conditions, their compatibility for the specific pneumatic system
must be based on specifications or after analysis and/or tests to
meet your specific requirements.

2. Only trained personnel should operate pneumatically
operated machinery and equipment.

Compressed air can be dangerous if an operator is unfamiliar
with it.Assembly, handling or repair of pneumatic systems should
be performed by trained and experienced operators.

3. Do not service machinery/equipment or attempt to
remove component until safety is confirmed.

1) Inspection and maintenance of machinery/equipment should

only be performed after confirmation of safe locked-out
control positions.

2) When equipment is to be removed, confirm the safety process

as mentioned above.Switch off air and electrical supplies and
exhaust all residual compressed air in the system.

3) Before machinery/equipment is re-started, ensure all safety

measures to prevent sudden movement of cylinders etc.
(Bleed air into the system gradually to create back-pressure,
i.e. incorporate a soft-start valve).

4. Contact SMC if the product is to be used in any of the
following conditions:

1) Conditions and environments beyond the given

specifications, or if product is used outdoors.

2) Installations in conjunction with atomic energy, railway, air

navigation, vehicles, medical equipment, food and beverage,
recreation equipment, emergency stop circuits, press
applications, or safety equipment.

3) An application which has the possibility of having negative

effects on people, property, or animals, requiring special
safety analysis.

CAUTION

Ensure that the air supply system is filtered to 5 micron.

ISO Symbol (Fig 1) Installation

WARNING

Before commencing installation ENSURE Air and Power supplies are
ISOLATED
DO NOT install these Valves in explosive atmospheres
DO NOT install these Valves in Corrosive Environments
If it is intended to energise a Valve for an extended period Consult
SMC
Protect Valves from Water / Oil splashes and Welding spatter.
Ensure Valves are protected from freezing
When changing Voltages the Valve must be replaced completely.
These Valves cannot be dismantled due to their Structure.

Using VK300 Series for Vacuum

If it is proposed to use the VK300 in Vacuum applications ensure that
the VK33*V,and VK33*W types are specified.

CAUTION

The preveous mentioned Valves differ from that of Vacuum retention
types.
When using Vacuum pads mount an Air suction filter (ZF Series)
between the Vacuum pad and the Valve to prevent dust from entering
the Valve.
Use a silencer in the Exhaust port.

CAUTION

Prolonged Energisation

Specify VK33*E Type for the above application and ensure that the
Valve is switched every 30 days. For Emergency Dump operation
please consult SMC.

VK3000 Series

The Air supply Port is the No.1 port of this Series,and cannot be used
in Vacuum applications.

Using VK3000 as a 3 Port Valve

It is possible to convert the VK 3000 into a 3 Port V alve either Normally
Open or Normally closed by plugging a Cylinder Port, see below:

Mixed Mounting of VK300 Series and VK3000 Series (Fig 4)

It is possible to mount the VK300 onto the Manifold base of the
VK3000 Series.
(1) When specifying VV5K3-20 or VV5K3-40, ensure that the

appropriate Exhaust Port on the Manifold base is PLUGGED
using a rubber plug part No. VK3000-8-1, as this Exhaust port
becomes redundant when mounting 3 port Valves.

(2) The 3 port Valve can also be mounted on additional Manifolds i.e.

VV5K3-21, VV5K3-(S)41 and VV5K3-(S) 42 without additional
modifications.

CAUTION

• When converting a 5 port Valve, from 3 ports back to 5 ports
ensure that the exhaust plug is removed.

• When a 3 port Valve (VK300) is Mounted onto the Manifold base
of the VK3000 Series, the Valve function will be NORMALLY
CLOSED. If a NORMALLY OPEN function is required plug port No. 4
of a 5 port Valve.

• When piping from the Manifold base,the port No. 2, of the 3 port
Valve becomes the port No. 4 of the 5 port Valve. To avoid the
possibility of incorrect piping to the port No. 2 ensure that the
port No. 2 is plugged.

DIN Type Connector (Fig 6)

Connecting

Undo the fixing screw and remove the connector from the Solenoid
Valve terminal block.
After removing the fixing screw, insert a slotted screwdriver into the
slotted area at the bottom of the terminal block and the housing,and
lever open to separate the terminal block and the housing.
Undo the terminal screws of the block, insert the conductor of the
cable into the terminal and tighten the conductor via the terminal
screw.
Select the terminal housing direction, best suited for the application,
and insert the terminal block into the housing until it clicks into place.
Hand tighten the gland nut to retain the wires.

Connection Method for Lamp/Surge Voltage Protection Circuit (Fig 7)

When using a DIN connector with DC voltage connect the positive side
(-) to the symbol 2 of the terminal block.

Circuit Drawings (Fig 8)

Changing the Direction of the Connector (Cable)

After separating the Terminal block from the housing, the cable
direction can be changed 4 ways at 90º intervals.

WARNING

If the connector is fitted with a lamp, ensure that the lamp is not
damaged by the lead wire of the cable.

Applicable Cable. ( 2 conductors or 3* conductors)

Outside diameter of the cable should be ø3.5 ~ ø7mm.
Note 3 Conductor cables are used when connecting to Ground.

CAUTION

Ensure that the connector is straight during insertion or removal.

Appropriate tightening torque

M5 1.5~2{15~20}

Rc (PT) 1/8 7~9 {70~90}

Lubrication

The valve has been lubricated for life on assembly and requires no
additional lubrication.

CAUTION

However,if a lubricant is to be used, a turbine oil type #1 (ISO VG32)
should be used.
If a lubricant is used,continuous lubrication must be carried out as the
original lubricant will be washed away.

Voltage Leakage (Fig 9)

If using a C-R element in parallel with the switching element, the
leakage voltage will increase as the current flows through the C-R

element.
Keep the residual leakage voltage to 20% or less of the rated voltage
for AC coils and 2% or less of the rated voltage for DC coils.

Maintenance

WARNING

When changing the rated voltage the valve MUST be replaced,as it is
NOT possible to change the coil.
It is NOT possible to dismantle the valve due to its design.
Application of undue force to the valve may damage the valve section.
