STANDARD FEATURES
|
ADVANTAGES
|
Heavy Duty Gears
|
Can withstand stall conditions reducing down time due to gear failure.
|
Permanent Lubrication
|
Little or no maintenance
|
NEMA 4x Enclosure
|
Provides protection against splashing, seepage, falling or hosedirected water and severe external applications; they are sleetresistant but not sleet-proof.
|
Open/Close Limit Switches
|
SPDT limit switches permit independent fine tuning of open and close positions.
|
Easy Adjustment
|
Cam-adjusted limit switches assure fast and easy field adjustments.
|
Visual Indicator
|
Visual valve position indication.
|
Universal Mounting
|
Actuators can be mounted and operated in any position.
|
Reversing Motors
|
Actuator can be used on diverse valve types and in a wide range of applications.
|
Powder Coating
|
Thermally bonded polyester coating provides a high degree of corrosion resistance.
|
Stainless Steel Fasteners
|
Provides maximum corrosion protection for severe applications.
|
Terminal Strip
|
Assures fast and easy field installation.
|
Factory Wired
|
For light indication of valve position.
|
Thermal Overload Protection
|
For motor protection should the actuator become stalled.
