Signal pressure Max. 1.0 MPa Note 1)
Set pressure range 0.14 to 0.7 MPa Note 1)
Shut-off pneumatic circuit pressure
Max. 0.7 MPa

Differential Note 2) 0.01 MPa
Weight 0.45 kg 0.64 kg 0.7 kg
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
¡The lock-up valve is used if any air source or air supply piping line failure occurs in the
air operated process control line.
Single acting, Double acting: Retains pressure at the operating area as emergency operation until the air
source is recovered to its normal state.
3 Port: Changes the supply port if a trouble occurs.

How to Order
The signal air pressure enters the upper diaphragm
chamber qto generate a force. When this force is
larger than the force generated by compressing the
adjusting spring e, the upper diaphragm wis
pushed up, the exhaust port ris closed, and the
signal air pressure enters the lower diaphragm
chamber tand acts the lower diaphragm y. This
pushes down the piston uto 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 wis pushed down, the pressure
inside the lower diaphragm tis exhausted from
the exhaust port r, and the valve iis closed by
the force of the spring o. 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 !0.
