Section 1: Introduction
Introduction
1.11.5 Due to the interaction of these variables, it is difcult to specify a "normal"
operating time. Faster operating time may be obtained by using one or more of
the following:
1. Larger supply lines
2. Larger control valve
3. Higher supply pressure *
4. Quick exhaust valves
— * Not to exceed maximum operating pressure of actuator or
control components
1.11.6 Slower operating time may be obtained by using ow control valves to meter the
exhaust. Excessive exhaust ow metering may cause erratic operation.
1�12 Actuator Operation
1.12.1 Controlled Operation: Controlled operation is accomplished by pressurizing and/
or depressurizing the appropriate cylinder inlet(s) of a double-acting. Do not
exceed pressures indicated on actuator nameplate.
1.12.2 Manual Operation: All pressure must be vented or equalized on both sides of the
pneumatic piston prior to manual operation.
