D10022 Page 4 August 2012
Description
The G-Series Cylinder Actuator is a totally enclosed, quarter turn, pneumatic operated actuator. A 2"
(50mm) square nut on top of the actuator is provided for manual operation. It is supplied with a single
cylinder, and single or double booster cylinders dependent on application.
Air Supply
The supply pressure to the cylinder should be between 50 and 100 psi (344 and 689 kPa).
Lubrication
The G-Series Cylinder Actuator has been lubricated at the factory and requires no routine lubrication. If the
actuator is disassembled, lubricate the rack, rack guide, gear sector and bearings using one of these lubricants:
- Keystone Zeniplex-1 (recommended)
- Amoco Amolith Grease #1-EP (alternate)
- Amsoil GHD (alternate)
- Mobil Mobilux EP 1 (alternate)
- Petro-Canada Vultrex MPG EP 1 (alternate)
- Shell Alvania EP 1 (alternate)
- Texaco Multifak EP 1 (alternate)
If the cylinder is disassembled, it must be lubricated as described in the cylinder instructions.
Actuator Identification
The G-Series Cylinder Actuator is available in three sizes: G6, G12 and G16. See Figure 1 for actuator
identification.
