1-1 Product features
■Double-acting type cylinder
(1) The cylinder space which is enclosed by the case ①and the
covers ⑥and ⑦is divided into airtight chambers ⓐand ⓑ
by the pistons ⑤and the piston packing ㉔.
(2) The shaft
②
penetrates the chamber
ⓑ
of the case. The yoke
③
is
fitted in the hole across the shaft in such a way that it allows it to slide
in the hole. The top of the yoke is connected with the parallel pins
㉜
so it rotates in accordance with the movement of the pistons.
(3) The compressed air enters chamber ⓐthrough port A and
pushes the pistons. The air in chamber ⓑis exhausted through
port B as the pistons move due to a pressure difference
between the two chambers. Integrated with these pistons, the
parallel pins ㉜also move and torque in the shaft is generated.
■Single-acting type cylinder
(1) The cylinder space which is enclosed by the case ①and the
covers ⑥and ⑦is divided into airtight chambers ⓐand ⓑ
by the pistons ⑤and the piston packing ㉔.
(2) The shaft ②penetrates the chamber ⓑof the case. The yoke
③is fitted in the hole across the shaft in such a way that it
allows it to slide in the hole. The top of the yoke is connected
with the parallel pins ㉜so it rotates in accordance with the
movement of the pistons.
(3) The compressed air enters chamber ⓑthrough port B and
pushes the pistons. The air in chamber ⓐis exhausted
through port C as the pistons ⑤move and the spring ㊷is
squeezed due to a pressure difference between the two
chambers. Integrated with these pistons ⑤, the parallel pins
㉜also move and torque in the shaft is generated.
(4) When air supply to Port B is stopped, the pistons are pushed
back due to the force of the spring ㊷and torque in the shaft
is generated.
1-2 Operating principle
This product is a pneumatic rotary actuator driven by pneumatic pressure of 0.4 to 0.7 MPa for the purpose of
actuating a 90˚ butterfly valve. The case is of aluminum alloy which is fabricated by means of extrusion. This manu-
facturing method enables the cylinder to be light weight, compact in design and highly accurate. The attachment
installation member complies with the NAMUR standard. NAMUR standard attachment parts can be installed directly.

①The table shows the torque at an operating air pressure of 0.4 MPa.
②Output torque for an operating air pressure of P MPa is given by : = P x (torque value obtained from the
table)/0.4. (Only double-acting type cylinder)
③In the case of single-acting type cylinders, the spring force does not change even if the operating air pressure is
changed. Thus the torque indicated by the dotted lines is constant regardless of the operating air pressure.
④In the case of single-acting type cylinders, the output torque value at openclose is different from that at close
open. The continuous lines and dotted lines indicate the torques respectively.
7G (Open with pressure) 7F (Close with pressure)
Continuous line Torque at closeopen with air pressure Torque at closeopen with spring
Dotted line Torque at openclose with spring Torque at openclose with air pressure
⑤A valve for the single-acting type cylinder should be selected referring to the torque indicated with a dotted line.

•Do not use a spanner, a monkey wrench, or the
special lever in the following cases as it could result in
a dangerous situation.
(1) For single-acting type cylinders, do not set the
position to open or close manually using a spanner,
a monkey wrench, or the special lever. Otherwise,
the spanner, the monkey wrench, or the special
lever is pushed back by the spring force, which may
cause injury. Use a manual screw handle.
(2) For T750, since the operating force is large and
therefore dangerous, do not perform external
manual operation using a spanner or a monkey
wrench. Use a manual gear.
•Depending on the type of accessories, the special
lever may not be usable.
