loW pRoFilE, coMpact,HIGHTORQUEDESIGNThe Series 70 is by ar the mostcompact, lowest profle design o anyelectric actuator delivering compara-ble torque output. Thorough researchand many years o feld experiencehave gone into the development othis state-o-the-art actuator the

product of the future. This design o-ers the advantages o greatly reducedspace requirements, lighter weightand ease o installation and main-tenance when compared to otherelectric actuators. When mounteddirectly to Bray valves, the Series 70 isespecially compact.

DIRECTMOUNTINGOFTHESERiES 70 on bRaY ValVESBray actuators mount directly to Brayvalves without using any externallinkage. Field installation is simpleand misalignment is minimized. Forsanitary processing and outdoorapplications, the Bray direct mount-ing system reduces the possibility ocontamination buildup or corrosionbetween the valve and actuator. Themounting pattern complies with ISO

5211 and VDI/VDE 3845 (NAMURrecommendations). Standard rota-tion is 90 reversible. Bray can providelinkages or mounting the Series 70 toother devices requiring 90 rotation.Please consult the Bray actory orurther inormation.

MECHANICALTRAVELSTOPSStainless steel mechanical travelstops permit precise eld adjust-ment o actuator movement tospecic degrees o rotation. Thetravel stops are located outside thebase or easy readjustment withoutremoving the cover. Stainless steellock nuts with O-ring seals hold thetravel stops securely in place. Thetravel stops are normally set at theactory to allow 0 and 90 travel.

TRAVELLIMITSPDTSWITCHES

(a) Bray has provided two SPDTmechanical switches as standard.These durable, high quality switchesare mechanically isolated and electri-cally independent. The dedicated

circuits eliminate any voltage cross-over between the switches. Thisswitch combination is used or bothopen and closed positions o thevalve and requires only one cam oreach direction o valve travel. Braysdesign provides synchronicitybetween motor control and positiondisplay. Switches are easily accessiblewithout intererence rom othercomponents. Each switch is markedwith open or close labels and the

cams are color coded, green or openand red or close, eliminating the pos-sibility o making wrong adjustmentso travel limits or eld wiring errors.

The Series 70 is supplied with a SPDT

Bray has gained UL, CSA and CE cer-tications on most intermittent andcontinuous duty actuators. These cer-

tications insure that the Series 70 hasbeen designed to the highest qual-ity requirements and most stringentsaety standards worldwide. Substan-tial resources have been invested

to assure our customers that the

Series 70 is the best actuator on themarket and will remain so.

SPECIFICaTIONS

The electric actuator shall becompact and lowprofle to greatlyreduce space requirements. Theactuator shall eature ease o accessto feld wiring and adjustment. Theactuator shall be built to withstandline vibration and shock withoutailure and shall bolt directly to Brayvalve mounting anges withoutusing brackets.

MotoR A single phase perman-

ent split-capacitor reversible motorwith voltages o 120 and 220 VAC50/60 Hz shall be standard. Motorinsulation shall be Class F or better.The motor shall contain a built-inUL approved automatic reset thermaloverload protector set at 275F(135C) embedded in motor wind-ings. A variety of 3-Phase 50/60 Hzand DC motors shall be availableupon request.

DUtY cYclE The duty cycle orintermittent on-o operation shall be25%. The continuous duty actuatorwith Servo shall be rated or 100%modulating operation.

SElF-locKinG oUtpUt DRiVE aSSEMblYThe actuator shall have a sel-locking output driveassembly consisting o a worm and worm gear outputdrive mechanism. The output drive assembly shall haveprecision cut multi-staged gears which will withstandlocked rotor conditions. The output drive assembly shallbe permanently lubricated at the actory and shall drivea chrome-moly steel worm which drives the compositealuminum bronze segmented worm gear / output shat.

WiRinG Actuator switches shall be pre-wired to aterminal block or ease o access and all internal wiringshall range from 12-22 AWG.

SWITCHESAll travel switches shall be Single Pole,Double Throw, Form C type, 10A at 125/250 VAC,1/2 A at 125 VDC, UL listed and CSA approved. Travel

Limit switches shall limit actuator in both the open andclosed position o valve travel.

caMS Cams or each travel limit switch shall beinfnitely adjustable by fnger touch or screw driver,as provided by Brays patented design.

conDUit EntRiES All units shall have 2 conduitentries. Conduit entries or models 003 and 005 shallbe either 1/2" NPT or M 20. Conduit entries or models008 181 shall be either 3/4" NPT or M 25.

MECHANICALTRAVELSTOPSMechanicalstainless steel travel stops shall be located outside theactuator or ease o adjustment and contain stainlesssteel lock nuts to hold the travel stops in place.O-rings provide waterproo seals. The travel stopsshall limit the actuator movement to specifc degrees

o rotation.

ManUal oVERRiDE All units shall be equippedwith an aluminum manual override handwheel torotate the valve without electrical power. The over-ride assembly shall ensure positive and ast manualoperation without the use o extra tools or levers.

EMERGENCYSHUT-OFFAn automatic powercutout switch shall be provided to cut power tothe motor when actuator handwheel is engagedor manual operation. This switch shall unction asa saety emergency shutdown device and shall beaccessible rom outside the housing.

EncloSURE The die-cast aluminum enclosureshall be certied to UL, CSA & CE waterproofstandards (NEMA 4, 4X, IP 65). Cover shall bepolyester powder coated or exceptional corrosion,wear, impact and UV resistance. The enclosure shallhave captive cover bolts, thereore preventing timeconsuming problems due to lost or misplaced bolts.A UL listed waterproof / explosion proof enclosure(NEMA 4, 4X, 7, 9) shall be available.

ValVE StatUS DiSplaY The actuator shallhave a highly visible display prominently labeled toindicate valve position throughout the ull range otravel.

tEMpERatURE RatinG Actuators shall bedesigned or temperature ranges o -40F (-40C)to +150F (65C).

optional EqUipMEntThe actuator shall be designed to include any othe ollowing accessories as an option.

toRqUE liMitinG SYStEM with 2 SPDTmechanical switches and 2 actory calibratedscrews. The worm shat shall be driven againstthe torque disc springs in response to the output

torque. The switches contact the worm shat groovein response to predetermined loads and interrupt theelectrical power to the motor. Switches shall operateat any point o actuator travel.

HEATERwith sel-regulating temperature control toprevent condensation buildup. The heater shall bepre-wired to the terminal block. Rated output is 15 Wat 24, 120 or 220 VAC.

SERVo A microprocessor controlled Servo shall beavailable or precise modulating control o valveposition in response to an analog input signal. The

Servo shall have an analog output signal proportionalto actual valve position as standard. This analog signalshall be confgurable to either current or voltage out-put. The Servo shall have voltage spike protection on allInput terminals. Independent adjustments shall be pro-vided or both open and closed Speed Control o theactuator and deadband. Input Signals: 4-20 mADC into250 Ohm, 0-10 VDC, 0-5 VDC, 10k Ohm or greaterpotentiometer. 10K Ohm Potentiometer shall be usedor internal eedback. Calibration o the Servo shall beaccomplished by pressing a single button to initiatethe calibration routine. Inputs or the control box andhandwheel, LED status indicators and self-diagnosticcapability shall also be provided.

DeviceNet Servos shall be available.

contRol Station or manual local electrical

operation o the actuator. The Control Station shallush mount to the actuator and feature a local / off /remote control switch, an openstopclose switch, andtwo lights which locally indicate open and closed valveposition. The enclosure shall be aluminum and water-proo (NEMA 4, 4X, IP 65).
