4.- Installation, Tube & Fitting
4.1.-The installation environment should be avoided in high temperature, low
temperature, high moisture and corrosive place.
4.2.- The conduit is usually use brass and stainless steel pipe , try to avoid
vibration, it’s easy to make the tubes slapped, damaged, otherwise it will cause to
leakage. It’s necessary to take action when violent vibration. For it may vibration
or impact during transportation, check the interface of all tubes before using the
products, if there are any slaps or leakage, please screw the interface till no
leakage.
4.3.-The conduit size of electrical accessories:
The different pneumatic actuators have different air inlet sizes, from 3/8” to 2”,
users should choose the tube size according to specific requirement. The air inlet
is sized by different pneumatic actuator size. Detailed sizes please refer to the
following table:

4.5.-The quick operation actuator must use bigger size air tube. Choose the
same size brass, stainless steel or flexible metallic tube from compressor or air
reservoir to actuator tubes.
4.6.- Operating media is filtered dry air, dew point over -15°C must use dryer.

5.- Operation
5.1.- Auto-Operation
On/Off Control Pneumatic Actuated Valve:
A) The valve open when solenoid valve energized (Failure Close Type)
B) The valve close when solenoid valve de-energized (Failure Close Type)
C) The valve close when solenoid valve energized (Failure Open Type)
D) The valve opens when solenoid valve de-energized (Failure Open Type)
Modulating Control Pneumatic Actuated Valve:
To give 4-20mADC signal to Electro-Pneumatic positioner(or 0.02~0.1Mpa to
Pneumatic–Pneumatic positioner) the valve position can be proportional
controlled by the input signal.
5.2.- Manual Operation Way
5.2.1.- Double Acting Pneumatic Actuator declutchable worm gear manual
override the declutch able worm gear manual override are sued for SY01F14 &
SY01F16 double acting pneumatic actuators.

To release the air firstly, How to operate the declutchable manual override, to
engage manual operation. First pull out the lock handle, and then rotate the clutch
lever in anti-clockwise direction until engagement takes place. To return the
automatic mode, first pull out the lock handle, then rotate the clutch lever in
clockwise direction until engagement takes place.
5.2.2.- Single Acting Pneumatic or hydraulic Actuator
5.2.2.1.- Jackscrew Operator
The jackscrew operator only available in SY01F14 & SY01F16 single acting
actuator which is side mounted operator. Turning the hand wheel, control the
valve position by screwing in & out the trapezoid screw in spring case. For the
valve, turn hand wheel clockwise to open, counter-clockwise to close.
SY01F14 & SY01F16 after manual operation, screw out the trapezoid screw
when it change to auto-operation way, to ensure the auto-operation smoothly
realized. Avoid to screw out integral trapezoid screw, the valve open & close
position will be influenced if the screwing is not in place.

5.2.2.2.-Hydraulic Manual Override
The hydraulic manual override is used for SY01F25 ~ SY01F60. The
hydraulic manual override is an integral device which consists of manual pump,
tank, globe valve, check valve and other parts, easy to operate and maintain. The
major parts as follows:
The Operation of Hydraulic Manual Override:
a). Close globe valve(1), open globe valve (2);
b). Inject oil to the oil cylinder by operating manual pump through lever handle,
piston of oil cylinder press the spring to open valve.
c). Close globe valve (2).
d). When close the valve, Open the globe valve (1) & (2) After manual
operation, open globe valve (1) & (2), at the meantime when it change to
auto-operation way.

6.- Stroke Adjustment
The stroke adjustment is available from 80° to 100°
The way of stroke adjustment:
Loosened the stroke nut firstly,
a. Screw out the open direction stroke bolt, open position increased, screw in
the open direction stroke bolt, open position decreased,
b. Screw out the close direction stroke bolt, close position increased, screw in
the close direction stroke bolt, close position decreased
Note: Please note to tighten the bolt nut after adjusting the appropriate on/off
position.
