Adjustment

The pneumatic actuators zero position have been initial adjusted in the factory, but can not guarantee completely consistent with the position of valve or other adjust mechanism ,need to adjust, zero adjustment suggestions according to the following steps:

1) Cut off the air supply and fully exhaust, to ensure that the pneumatic actuator in the initial closed position;

If the valve or other adjust mechanism were closed overdone, should do as following:

a) Get through the air and gradually increase the pressure, make the valve or other adjust mechanism to arrived at the specified closed position;

b) Release the nut of the adjust screw or adjust bolt;

c) Rotate the adjust screw in clockwise direction until the adjust screw stand up to the pneumatic actuator

d) Remove the pressure, make the valve or other adjust mechanism to arrived at closed position with the force of spring;

e) Lock the nut;

7 Advice and warning

1) Because the pneumatic actuator weight is great, advise that give support in the middle of the spring cartridge at the installation site;

2) Air supply shall be clean, non corrosive components compressed air or other gas agreement;

3) The air pressure is given according to the design pressure in principle. If due to conditions to raise the pressure,the assessment should be performed. But the maximum air pressure should be not more than 0.6MPa;

4) The spring sleeve and end covers are the protection structure of the spring. Cause the spring pre-compressed force is large, and therefore should not be arbitrarily loose fastening screws or bolts of the spring sleeve end covers, so as to avoid the injury accident.

5) Self inspection maintenance, should ensure that the air supply s cut off and fully discharge pressure, at the same time get technical support from the supplier.
