Declutchable Gear Override
DeclutchableGO
The Declutchable Gear Override “Sandwich Mounts” between a pneumatic quarter-turn actuator and a ball, butterfly, plug or damper valve. This rugged device allows for manual operation during installation, system testing and in the event of an air supply failure. The DGO Series mounts directly to many of the most popular rack and pinion style actuators on the market, and does not require a bracket between the pneumatic actuator and declutchable override. The units come complete with a three-stage coupler that connects to the pneumatic actuator through the gear override and to the valve (or coupler). Output torques cover a broad range of pneumatic actuator and quarter-turn valve sizes that require the convenience of a manual override. FEATURES: There are 2 Industry Standard Mounting Patterns: 3RDGO – Matches the ISO 5211 dimensions 3KDGO – Matches the Keystone 3.25 and 5.00 bolt patterns 3 Stage Coupler (Actuator, Gear, Valve) Rugged Declutch Lever and Engagement Handle BBV – Block and Bleed Valve to exhaust air supply from actuator

E-Series (Original Style) Triac® Electric Actuator
ETriacEA
The original product line of TRIAC electric actuators, E Series electric actuators offer torques from 300 to 30,000 in. lbs. and numerous features including manual overrides, auxiliary switches, 4-20mA modulating control, several voltage options including 1-phase 24/120V/220V - 12 and 24VDC, 3-phase 220v, 380v, and 440v (view voltage chart). The units feature EP-CYCLICAL gear trains and a unique manual override with handwheel. All actuators are Type 4x and are designed for maximum cycle life due to our rugged motors and gear trains. As with all TRIAC actuators, our E Series electrics are available with mounting kits on most ball, butterfly and plug valves. The actuators are ideal for use on butterfly and louver dampers with the increased benefit of self-locking EP-CYCLICAL gears, eliminating the need for unreliable solenoid brakes. E Series Electric Valve Actuators Feature CSA and CE Approved Corrosion resistant Type 4, 4x construction Self-locking EPI-CYCLICAL gear train Standard manual override with handwheel Visual position indicator Standard two auxiliary limit switches (10amp at 120VAC) Torque swtiches (2) standard on models ETI-8600 and larger Optional servo card for modulating service ISO5211 mounting patterns 14º-160ºF working temperature E Series Electric Valve Actuator Options Potentiometer A optional potentiometer can provide a resistance (0-135ohm, 0-1Kohm, 0-5kohm, 0-10kohm) signal proportional to the actuators position. The potentiometer can give continuous feedback to control panels and other closed loop devices. Three Position Control The E-Series actuator can be configured to have three distinct positions. The three position controls is useful in filling applications and multiported valves. Two Wire Control When using the optional two wire control, the E-series (2) position electric actuator can be controlled with a low voltage signal. When the voltage is present the spring loaded relay will trip energizing the actuator to rotate clockwise or counter-clockwise. When the voltage is removed the spring will untrip the relay, energizing the actuator to rotate in the opposite direction. DC Modulating Card The Triac DC modulating card (4-20mA input) can be used with the Triac E-Series DC powered actuators. Dynamic braking reduces motor coasting and provides improved control. Low standby current (22mA typical) when the actuator is not in operation. Speed Control The Triac Speed Control is a compact module that extends the operating time of the E-Series AC powered actuator by pulsing the motor on and off. Extending the cycle time of an actuator can avoid problems associated with water hammer and control system instabilities. Control Boxes Control boxes are available for a variety of local control options, such as local/remote open-off-close and jogging control. NEMA 4 housings are used as standard, but other housings are available upon request. E Series Modulating Control Features 10 bit Microprocessor Controller for precise positioning - eliminates the need for an external deadband control. Programming of the controller is accomplished by a combination of push buttons and seven position DIP switch without the need for a command signal. Input signals can be 4-20mA, 0-10VDC, 1-5VDC, Command signal potentiometer. The TMC2 can be programmed to fail in place, fail clockwise or fail counter clockwise on loss of command signal. Characterize control - Linear, Quick opening (square root) or equal percentage (square) relationship between the actuator position and the command signal. On Board - 4-20mA Transmitter (Optional).
