ACTUATION
Accessories
Our electric actuators can be supplied with a selection of accessories to adapt to specific control demands and automation requirements.
- Integral potentiometer – Available in a variety of resistance ranges to interface with most common control devices; available for all models of RCS actuators.
- Auxiliary limit switches – Available in SPDT or DPDT configurations for additional control requirements and are independently adjustable.
- Interposing relays – Available with a variety of coil voltages to allow for operation when the control voltage differs from the actuator supply voltage.
Single and dual relay configurations are available for specific applications.
- Motor brakes – Maintains actuator position and minimizes back drive created by dynamic torque in certain valve and flow applications. (Standard feature on all SurePower models and modulating service applications)
- D.C. analog position transmitter (with integral power supply) – Provides analog position indication proportional to actuator travel.
- D.C. analog position controller – The ACT-100 analog control module is capable of being configured to a variety of common control input and output signals and features self-calibrating technology. A variety of embedded control and setting menus provide for precise settings to satisfy complex loop control demands.
- Digi-Tork bi-directional torque control – Electronic current sensing device which protects the actuator from damage created by excessive torque demands.
- Digi-Speed variable speed control – Electronic timer that allows for extension of actuator cycle time to minimize water hammer or any other piping shock created by sudden flow reversal within a piping system.
