Features & Benefits:
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.
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.
CAPTIVE COVER BOLTS: The cover is attached to the base by captive stainless steel bolts placed outside the sealing area.
O-RING SEAL FOR WATERTIGHT ENCLOSURE: The O-ring seal between the cover and base provides a weatherproof seal preventing internal corrosion.
MANUAL OVERRIDE: Standard on all models. The declutchable 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.
MANUAL OVERRIDE SWITCH: Interrupts power to the motor when handwheel operation is engaged.
CONDUIT ENTRIES: Two connections in either NPT or metric threads. One entry is for power, the other for control wiring.
MOTOR GEAR: High torque start motor assembly. Designed for fast inspection and maintenance.
OUTPUT DRIVE: Self-locking worm shaft and worm gear assembly holds the valve in desired position.
MECHANICAL TRAVEL STOP BOLTS: Designed to prevent over-travel in the open or close direction during manual operation. Travel stop bolts include a locknut to prevent loosening, seals to prevent water ingress, and spacers to prevent adjustment between 0° and 90° limit switch settings. Travel stop bolts permit 5° of over travel.
TERMINAL STRIP: Actuator limit switches are pre-wired to an easily accessible and clearly marked terminal block for customer wiring. The terminal strip has been placed near the two conduit entries with ample room for running wire leads. An easily accessible green plated ground screw is provided. A wiring diagram is included inside the cover for easy reference.
LIMIT SWITCH BRACKET: Simple and secure design to firmly hold limit switch assemblies for accurate and repeatable valve position feedback.
LIMIT SWITCH CAMs: Bray’s patented CAM design includes standard green (open) and red (close) CAMs which are adjustable with finger touch or screwdriver with no additional tools. Standard factory setting allows 90° travel between open and close positions.
ROLLER BEARING: Provides low friction while securely aligning actuator indicator shaft and CAMs for reliable valve position feedback.
OLDHAM COUPLER: Corrects any misalignment between the valve and actuator without introducing side load to the position indicator shaft assembly.
