Series 70
Features & Benefits
Output Torque 300 in-lb (34 Nm) to 18,000 in-lb (2,034 Nm)
Decades of Bray's proven success in electric actuation, combined with innovative engineering, has produced the Series 70 electric actuator. The Series 70 features on/off or modulating control and offers many advantages over other actuators including:
- UL, CSA and CE certification of most units
- Wiring directly to the terminal strip without interference from other components
- Simple and unique manual override handwheel system
- Lowest profile and lightest weight actuator on the market
- Simple finger or screwdriver adjustment of travel limit cams without interference from other components
- Highly visible valve status display on most units (Heartbeat)
Series 70 Design Features
Designed like a junction box, the Series 70 offers by far the easiest access to terminal block wiring, cam adjustments and switch installation. Therefore, the time required for field startup and adjustment is greatly reduced, and maintenance can be performed with assured ease and safety.
A. Enclosure
The low profile weatherproof actuator is UL listed Type 4, 4x and IP65. Polyester powder coated die-cast aluminum cover and base, for exceptional corrosion, wear, impact and ultraviolet resistance.
B. High Visibility Position Indicator
Prominently labeled and color coded yellow for open, red for close – the display indicates valve position through the full range of travel. The O ring sealed dome is made of high impact, heat, chemical and ultraviolet resistant clear polycarbonate and designed to withstand caustic wash down ensuring excellent corrosion protection
C. Captive Cover Bolts
The cover is attached to the base by captive stainless-steel bolts placed outside the sealing area.
D. O-ring Seal for Watertight Enclosure
The O-ring seal between the cover and base provides a weatherproof seal preventing internal corrosion
E. Manual Override
Standard on all models. The declutch-able manual override prevents handwheel movement during motor operation. When manual operation is desired, pull the handwheel out exposing a yellow stripe around the handwheel shaft. This indicates the handwheel is engaged and manual operation is available
