► Dimension-Pneumatic Actuator
► The use of the pneumatic actuator with hydraulic Manual Override
1) When adjust or run(automatically) the pneumatic actuator of JDP
heavy-duty pneumatic actuator with hydraulic manual override, the
oil drain handle should in the relaxed state, others are same with
the related programs of standard pneumatic mechanism.
2)Hand operating steps:
a) Cut off the air supply, in order to avoid the damage of the
components caused by the impact(made from the repeated air supply
and no air supply) on the pneumatic actuator;
b) When the oil drain handle is in a relaxed state, lift up and put
down the handle ten times or more times to exhaust the air in the
c) Lock the oil drain handle, enter the handle operating situation.
By lift up and put down the handle to make the pneumatic actuator
to get the regulated position.
Note: The hydraulic pressure is large when conduct hand operation,
please do not operate to the totally open position as far as
possible in order to avoid the damage of the inner components of
the pneumatic actuator!
3)Recovery automatic control program:
a)Release the oil drain handle, to make the pneumatic actuator to
back to the closed position under the spring force;
b)Connect the control path;
c)Connect the air supply, recovery the automatic control.
4)Attention of hydraulic oil filling and treatment
a)Must use the corresponding hydraulic oil according to the
temperature of the working site;
|Working temperature||Types of hydraulic oil||Remark|
|-10℃～40℃||HM type wear-resistant hydraulic oil|
|≥-30℃||HV type low temperature hydraulic oil||Could not use with the HS type hydraulic oil|
|≤-30℃||HS type low temperature hydraulic oil||Could not use with the HV type hydraulic oil|
b) The fuel tank has marked rated capability, filling quantity of
the hydraulic oil tank capacity should be not less than 90%, and
should periodically check the oil quantity;
c)The replaced hydraulic oil should be handed over to the relevant
institution reclaim or treat according to local regulations or
