Product Data Sheet RGS011110-6 Rev. 0 Operation and Piping Bettis RGS Q-Series actuators may be operated with instrument air, hydraulic fluid, water, or other power gases and fluids. Always ensure that the materials of construction are compatible with the application and that the pressure does not exceed the maximum allowable. All Bettis actuators are shipped in the Fail-Close or Left-Hand orientation unless ordered as Fail-Open or Right-Hand. The mode of operation may be reversed in the field simply by turning the actuator top-side down. 1. Fail-Close (Left-Hand): pressure on the end cap...

Bettis RGS Q-Series March 2016 Product Data Sheet Piping Guidelines 1. Dual cylinder models (205, 210, 214), both endcap pressure ports (P1 and P2) must be utilized for proper operation. 2. P1 and P2 are typically connected together and powered by a single air pathway. 3. Single Cylinder models (203, 204, 207, 212), port 2 (P2) does not exist. 4. Spring-Return (SR) models port 3 (P3) is a breather port. 5. P3 is a pressure port for Double-Acting models. 6. P3 is a breather port for single cylinder SR models.
