G-Series Cylinder Actuator Used on BAW Butterfly Valves

Description

The G-Series Cylinder Actuator is a totally enclosed, quarter turn, pneumatic operated actuator.

The supply pressure to the cylinder should be between 50 and 100 psi (344 and 689 kPa).

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.

The G-Series Cylinder Actuator is available in two sizes: 6A and 12A. See Figure 1 for actuator

identification.

To determine the actuator size, measure the diameter of the cover - see Figure 1. To determine the

cylinder size, measure the diameter of the cylinder—see Figure 1 and Table A.
