Intended Use - GF PA30 Instrucciones Para La Operación

Intended use

1 Intended use
The following descriptions and instructions apply to pneumatic actuators Type PA30 – PA90
with DA, FC and FO function.
These actuators actuate valves with a pivoting range of 90° through a F04/05 interface with a
maximum actuating torque of 3840 Nm, and are operated by control air (3 – 7 bar) from an
external control source.
The following types of actuators are available:
 Double-acting pneumatic actuator (DA)
 Single-acting pneumatic actuator with spring for the fail safe to CLOSE position (FC)
 Single-acting pneumatic actuator with spring for the fail safe to OPEN position (FO)
The pneumatic actuator can be mounted on any part-turn valves with a F04/F05 interface as
defined in ISO 5211.
These pneumatic actuators are not intended for any types of application other than those
listed here! The following especially apply:
 Control pressures above 7 bar must not be used.
 The F04/05 interface must not be loaded with forces greater than those permitted by
prEN12570 (maximum retention forces for operating the valves).
 Pneumatic actuators must not be operated under water.
NOTE
HINWEIS
The pneumatic actuators will function correctly only if they have been connected correctly as
shown in the control diagram.
See Section 5 "Design and function", Page 36.
NOTE
HINWEIS
Possible risks of incorrect use:
 Non-observance of the valve and drive specifications can lead to premature wear and
tear, or cause the controlled valve to fail to open or close.
 Uncontrolled leaking of the control air can cause the valve to malfunction (valve fails to
open or close completely).
 Moisture in the control air can cause premature wear and tear, see Section 6 "Technical
specifications", Page 41.
 Blocking of the vent holes can cause the drive to move too slowly or to fail to move
through its entire control range, see Section 5.1 "Functions", Page 37.
