Instruction Manual
Lock-Up Valve
Series IL201/211/220
The intended use of these Lock-Up Valves is to control the air in the
secondary pressurized air system. Depending on the signal pressure the
types 201 and 211 are locking the air and the type 220 is relieving the air.
Validated according to ISO 13849.

including our products must be performed by an operator who is
appropriately trained and experienced.
Do not service or attempt to remove product and
machinery/equipment until safety is confirmed.
1) The inspection and maintenance of machinery/equipment should only
be performed after measures to prevent falling or runaway of the driven
objects have been confirmed.
2) When the product is to be removed, confirm that the safety measures
as mentioned above are implemented and the power from any
appropriate source is cut, and read and understand the specific product
precautions of all relevant products carefully.
3) Before machinery/equipment is restarted, take measures to prevent
unexpected operation and malfunction.
Contact SMC beforehand and take special consideration of safety

conditions.
1) Conditions and environments outside of the given specifications, or
use outdoors or in a place exposed to direct sunlight.
2) Installation on equipment in conjunction with atomic energy, railways,
air navigation, space, shipping, vehicles, military, medical treatment,
combustions and recreation, or equipment in contact with food and
beverages, emergency stop circuits, clutch and brake circuits in press
applications, safety equipment or other applications unsuitable for the
standard specification described in the product catalogue.
3) An application which could have negative effects on people, property
or animals requiring special safety analysis outside the scope of ISO
13849 described in this document.
4) Use in an interlock circuit, which requires the provision of double
interlock for possible failure by using a mechanical protective function,
and periodical checks to confirm proper operation.
Always ensure compliance with relevant safety laws and standards.
All electrical work must be carried out in a safe manner by a qualified
person in compliance with applicable national regulations.
Caution
The product is provided for use in manufacturing industries.
The product herein described is basically provided for peaceful use in

Notes:
Note 1) Provide a differential pressure of 0.1 MPa or more between the
signal pressure and set pressure.
If the differential pressure is small, the internal part is worn out due
to the structure of this product and the bleed amount from the
exhaust port increases, which may affect the characteristics.
Note 2) Pressure difference between lock activated and lock released.
Note 3) Under SMC test conditions. The B10 figure is estimated from SMC
life tests. The B10d figure is derived from B10 using the assumption
in EN ISO 13849-1:2008 Annex C. Contact SMC for details.
2.2 Principle of Operation
The signal air pressure enters the upper diaphragm chamber (1) to
generate a force. When this force is larger than the force generated by
compressing the adjusting spring (3), the upper diaphragm (2) is pushed
up, the exhaust port (4) is closed, and the signal air pressure enters the
lower diaphragm chamber (5) and acts the lower diaphragm (6). This
pushes down the piston (7) to open the valve. IL201 and IL211 enter the
status, in which the flow path between IN and OUT is opened. IL220 enters
the status, in which the flow path between IN1 and OUT is opened. If the
signal air pressure drops to a level below the set pressure for some reason,
the upper diaphragm (2) is pushed down, the pressure inside the lower
diaphragm (6) is exhausted from the exhaust port (4), and the valve (8) is
closed by the force of the spring (9). At this time, IN and OUT are shut
down in IL201 and IL211. In IL220, IN1 and OUT are shut down, and the
flow path between IN2 and OUT is opened. The set pressure is adjusted
with the adjusting screw (10).

3 Installation
3.1 Installation Warning
Do not install the product unless the safety instructions have been read
and understood.
3.2 Environment Warning
Do not use in an environment where corrosive gases, chemicals, salt
water or steam are present.
Do not use in an explosive atmosphere.
Do not expose to direct sunlight. Use a suitable protective cover.
Do not install in a location subject to vibration or impact. Check the
product specifications.
Do not mount in a location exposed to radiant heat.
3.3 Piping Caution
Before piping make sure to clean up chips, cutting oil, dust etc.
When installing piping or fittings, ensure sealant material does not enter
inside the port. When using seal tape, leave 1.5 to 2 threads exposed on
the end of the pipe/fitting.
Tighten fittings to the specified tightening torque.
3 Installation –continued
3.4 Lubrication Caution
SMC products have been lubricated for life at manufacture, and do not
require lubrication in service.
If a lubricant is used in the system, use turbine oil Class 1 (no additive),
ISO VG32. Once lubricant is used in the system, lubrication must be
continued because the original lubricant applied during manufacturing
will be washed away.

atmosphere.
After installation and maintenance, apply operating pressure and power
to the equipment and perform appropriate functional and leakage tests to
make sure the equipment is installed correctly.
If any electrical connections are disturbed during maintenance, ensure
they are reconnected correctly and safety checks are carried out as
required to ensure continued compliance with applicable national
regulations.
Do not make any modification to the product.
