AVCO Electric Actuators

AVCO electric actuators are available in a variety of configurations to meet your needs. All the electric actuators come standard with a NEMA 4/4X aluminum housing. The ISO 5211 mount pad allow for direct coupling to many valves resulting in a lower profile assembly. The shaft gives 90° rotation with a 180° option and its position is clearly shown on a raised indicator for quick visual verification. Manual override is standard on non-spring return units and is achieved without the need for levers to engage the override function. All actuators have an internal heater for moisture control, dual SPDT switches and positive mechanical stops on larger models. Most actuators are available through the range of 12V to 230V. The P Series electric actuators is a quarter turn, non-spring return actuator that fails in place. It is available from 300 in-lbs through 40,500 in-lbs. It may be configured with on/off/jog functionality or as a proportional actuator for greater control. The PS series is a reversible electric spring return actuator. The internal modular design eliminates excess wiring and allows for simple field conversion between 2 position and proportional control.

AVCO Pneumatic Actuators

The highly dependable AVCO pneumatic actuators come in two configurations – double acting and spring return. The actuators share the same design with the only exception being that one model has springs and the other model does not. This allows for the easy change over between double acting and spring return in the field or at the factory. They can also be switched from the standard CCW rotation to CW rotation. The actuators have an extruded aluminum body with die-cast aluminum end caps. A position indicator with NAMUR slot sits on top of the actuator body to allow for visual indication or mounting of a positioner or limit switch and the drive/mount pad meets ISO 5211. The actuator air inlet and exhaust ports are designed for direct mount NAMUR solenoids. Buna body seals come standard, but Viton seals are available for higher temperature applications and LNBR seals are available for cryogenic applications. Internal features include a blow-out proof pinion, dual opposed rack pistons and adjustable travel stops. The double acting actuators have a linear torque output for smooth operation throughout the valve cycle. As a default, AVCO sizes actuators on an 80 psi air supply, but torque values are provided for other air supply pressures as well. Modifications can be made to the actuators to achieve closing speeds as fast as 0.1 seconds. Actuators with stainless steel body and end caps are available when automation is needed in corrosive environments.
