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.

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.
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 Valve either Normally
Open or Normally closed by plugging a Cylinder Port, see below:
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.

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.

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.

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.

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.
