Spring Return Actuators (Open Position)
I.
Connect the actuator to pressurized air
system. Give some pressure to “Port A” to
open the actuator.
II.
Adjust the pistons to accurate position by
using wrench.
III.
Turn the left set screw until an obstruction
is felt. Do not turn anymore and do not force
it. For lock the set screw use lock nut.
Spring Return Actuators (Close Position)
I.
Release the pressure in “Port A”. Springs
would close the actuator.
II.
Adjust the pistons to accurate position by
using wrench.
III.
Turn the right set screw until an obstruction
is felt. Do not turn anymore and do not force
it. For lock the set screw use lock nut.
c. Mounting the Namur Solenoid
to Actuator Assembly
I.
Mount the solenoid to the actuator with
socket head screw by suitable tools.
Note:
To prevent the “water hammer”
connect the throttle valve(s) to the namur
solenoid exhaust(s) with suitable tool and
sealing. “Pressurized air discharge time can be
adjusted with throttle valve (s) thus the valves
Opening or Closing speed adjusted too.” For
this optional throttle valve, you should inform
us when ordering the pneumatic actuator.
Pneumatic connections should be
disconnected before any intervention.
For protection against potentially explosive
atmospheres use certified ex proof Namur
solenoid valves and “RX” code ex proof
pneumatic actuators.
