C) Operate the elastomer (O-ring type) of pneumatic actuator at least once every six months to
prevent their functional degeneration. Operate it to the full stroke even under general operation
conditions at least three times a month.
D) Do not remove the flange cap attached to the flange surface to prevent foreign substances from
penetrating into the system until ball valves are installed on the line.

3. Installation

Like any other valves, the Honeywell control valve must be installed carefully at first according to the
following cautions to use it for many years without malfunction.
A) Remove the flange cap and check whether there are any foreign substances in the body. If you find
foreign substances, remove them before starting installation.
B) As cast steel products are processed with rust preventive oil before shipping to prevent corrosion,
remove the rust preventive oil from the pipes before installing them on the line.
C) Blow off all foreign substances including welding chips in the pipes before starting installation.
To prevent damages to plugs and seats, you must blow out (flashing) foreign
substances such as weld beads, scales and chips from the pipeline
according to the prescriptions before installing the ball valve.
D) Install valves in the direction of arrow marked on the body.
♣ CAUTIONS
 When moving control valves, you should handle them carefully so that the components and air piping
will not be damaged. Otherwise, the electronic and electric parts such as solenoid valve, positioner, and
limit switch may get damaged or the valve travel may change.
 Be careful not to damage the sealing surface of valve flange.
 Apply thermal insulation as needed, but do not apply thermal insulation to the cooling fin and extensions.
