Series 92-93 Pneumatic Actuator

Operations and Maintenance Instructions

General Pneumatic System

Recommendations

To maintain maximum efficiency with the Series

92/93 actuator, as well as many other pneumatic

devices, the following suggestions are offered:

Air supply lines should be run in accordance with

a Standard Piping Practice, and should not have

exaggerated loops, which may trap condensate.

All pipe ends should be thoroughly cleaned

and deburred after cutting to ensure that the

pipeline is clear of cuttings.

Where air pipelines are subjected to extremes

of temperature, the system should be fitted

with air drying equipment.

If pipelines are hydraulically tested, the lines

should be “blown down” with high pressure

air to clear all water prior to connecting the

lines to the actuator.

Where a system is dependent on air filter

equipment, the air filters should be in posi-

tions that allow easy access for maintenance

and/or draining.

Where pneumatic valve positioners or pneu-

matic controllers are installed in a valve actuator

assembly, oil mist lubricated air should not be

used unless the manufacturer states specifically

that the positioner or controller is compatible

with lubricated air. In general, lubricated air

is not recommended for a positioner.

Where pipe fitting sealants or tapes are used, they

should be applied to the male threads only, and

limited to the first three threads. When applied

to female threads, excess compound or tape can

be transmitted into the actuator control lines and

cause malfunctions in downstream equipment.

Lubricators should be installed downstream

of regulators.

Eliminate or minimize sharp bends in the air

supply lines.
