DG-Series direct gas valve actuators are a simpler and more cost effective solution than gas-over-oil (gas/hydraulic) valve actuators. Rather than use the process gas to pressurise hydraulic fluid to provide the energy to operate the actuator, the process gas acts directly upon the valve actuator¡¯s piston. To ensure long and reliable operation, Paladon Systems ensures that, whatever the quality of the process gas, it is sufficiently filtered and conditioned before entering the control system and valve actuator. Numerous additional control system options are available; including linebreak detection (rate-of-drop and high/low) and remote control.
