TA3 SERIES(φ50~φ125)Pneumatic rotary actuator

  • TA3 SERIES Pneumatic rotary actuator
・Valve mounting interface:ISO5211 compliant.
・Solenoid valves mouting interface and optional actuator top mounting interface comply with NAMUR standards (VDI/VDE3845)
・Scotch yoke/double piston mechanism is adopted for compact design.
・Scotch yoke mechanism features improved driving efficiency allowing compact design, while providing optimum torque
 characteristics for controlling valves hich require maximum torque output at the start/stop ends of rotation.
・TA3 series and its options can be operated without lubrication.
・Single-acting(spring return)type incorporates spring cartridge.
