Request Information
The Bray Series 70 Electric Actuator provides a rugged, compact industrial actuator solution to a wide range of quarter turn applications including butterfly valves, ball valves, and dampers. Available in torque outputs from 600 to 18,000 lb.in. (68 to 2033 Nm), these actuators mount directly to Bray and other industry standard butterfly valves without the need for brackets and linkages. The manual declutchable override handwheel is standard on all Bray Series 70 actuators, providing end user convenience in installation, commissioning and service.

On/Off and modulating models are available in 24, 110 and 220 VAC. The standard enclosure is NEMA 4x and IP65 rated with an industrial polyester finish, making the Series 70 the ideal choice for cooling tower valves and other outdoor applications. The advanced Servo Pro modulating control card assures compatibility with virtually any analog control signal used in today’s building automation and temperature control systems.

Features
  • Compact design and direct mounting
  • UL, CSA and CE approved (most models)
  • High visibility beacon position indicator
  • Internal isolation relays
  • Manual declutchable override handwheel
  • Advanced Servo Pro modulating option
  • Optional battery backup on 24 VAC models
Benefits
  • Fits in tight spaces, installs easily
  • Assures universal application acceptability
  • Assists in field operation
  • Allows parallel wiring of multiple actuators from a single control output
  • Allows manual positioning without disconnecting power
  • Provides on-board diagnostics and user adjustable options including control signal type, speed controls and other features.
  • Assures return to a predetermined position upon loss of power supply

  • 1 Use Series 70 actuators only to control equipment under normal operating conditions. Where failure or malfunction of the electric actuator could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the electric actuator.
