ACTAIR NG

ACTAIR NG

Single-acting (DYNACTAIR NG) and double-acting (ACTAIR NG) pneumatic actuator for mounting on quarter-turn valves (butterfly valves or ball valves). Actuator flange to ISO 5211. Control pressure up to 8 bar. Mounts on valves with square or flat shaft end. Force transmission via scotch-yoke kinematics provides output torques of up to 8000 Nm (ACTAIR NG) or 4000 Nm (DYNACTAIR NG) which are ideal for actuating quarter-turn valves. Reset to fail-safe position in case of control air failure (DYNACTAIR NG) is effected by means of spring assemblies. Equipped with a visual position indicator and, depending on the actuator size, adjustable travel stops for open/closed position or closed position as standard. Optional separate or integrated manual override. Suitable for mounting control unit type series AMTROBOX, AMTRONIC, SMARTRONIC or any other device with an interface to VDI/VDE 3845.
