SERIES SURE 49

Electripowr TM Type SR

600 Inch Pound Torque Output

Description

bulletHighly reliable
bulletCosts less to install and operate than pneumatic and hydraulic actuators
bulletShock absorber feature graduates emergency operation to prevent shock damage to piping, valve and actuator.
bulletIdeal for valve and damper applications where high reliability, accurate open/close speeds and automatic emergency shut-off are desirable.

Applications

bulletEasy, Low cost Installations. connects to standard 2-wire, 120 Vac 60Hz, 1 Ph, power line. (Optional 220 Vac, single phase)
bulletLow Maintenance and Operating Costs. No pumps, compressors or troublesome hoses and tubing. Requires less electrical power than pneumatic and hydraulic systems.
bulletProven Dependability
bulletIdeal For Automated Systems
bulletThe Most Economical, High Performance electric Rotary/ Spring Return Actuator Available

Will Automate

bulletBall Valves - 1/4" to 2"
bulletButterfly Valves - 2" to 4"
bulletPlug Valves - 1/4" to 1 1/2"
bulletSwitches
bulletSafety Devices

Features

bulletAuxiliary switches for light indication and other switching functions
bulletHeaters and thermostats
bulletSpecial corrosion-resistant coatings
bulletActuator control stations with many combinations for local or remote control
bulletCSA approved enclosure 4 and hazardous locations: Class I, Groups C and D; Class II, Groups E, F and G.
bulletPositioning controllers for "On/Off," floating or proportional control. Controllers are designed to automatically proportion in relation to a resistance, current or voltage command signal. Command signal may be obtained from a sensor or a manual command potentiometer.

Optional Features

POWER ON: The electric motor, brake solenoid and spring control clutch are energized, diving the gear train which in turn winds the spring and turns the valve. An internal limit switch de-energizes the motor and enganges the solenoid brake which holds the return spring and valve in position.

POWER OFF: When the current is interupted by either a control signal or a power failure, the spring control clutch is de-energized which in turn disengages the gear train. The return spring drives the valve to its original postition. Shock damage to the valve and piping is avoided by graduating the speed of return with the integral shock absorber.

DRIVE DIRECTION: All surepowr models can be factory built for closkwise or countercloskwise spring return rotation, as viewed from top of actuator, looking at valve stem. Please specify when ordering.

SPECIAL NOTE:
Designed for intermittent operation as typified by applications which require emergency shutoff. For rapid cycling applications, consult factory.
