ABZ's Electric Valve Actuators are engineered to provide low cost and high performance electrical automation of quarter turn valves. With 14 year's experience in the field on electric actuation of valves, ABZ with the introduction of their ABZ Series Electric Valve Actuator, has improved reliability incorporating all the best features of self-locking gear's to withstand backdrive from valves, torque limit switches for over-load protection, hand-auto declutching facilities for manual override, thermal cutout protection for motor, water tight sealing and space heater to combat condensation in the housing.

ABZ Electric Actuators feature:

• Highly reliable and easily adjustable limit switches are provided along with a torque switch assembly as standard equipment.
  
• Precision gearing and use of ball bearings maximizes efficiency of power transfer with low noise level (Max. 50dB).
  
• Self locking at any position by means of worm gears.
  
• Adjustable mechanical stops give high safety factors at both ends of actuator travel.
  
• All ABZ Actuators have Hand/Auto declutching hand wheel overrides.
  
• Actuators are "CE" approved.
