Most important general features:

Linear output drive action (CVL)

Continuous unrestricted modulation duty - S9 Class

On-board datalogger as standard - actuator by smart-function for precise valve control & feedback

Configurable fail-to position mode by using supercapacitor technology

Explosion proof categories comlied with international standards

Single Phase or DC power supplies

Adjustable speed control

Direct torque and thrust measurment and monitoring

Bluetooth function for setup/ test/ maintain etc.

Accurate proportional control&feedback by 4..20 mA signal

Available choices for input-output characteritics/ preset by factory

Input Characterisation graphs: linear; equal percemntage; quick opening and Custom defined input versions

Free downloadable Enlight PC software for customer setup and monitoring possibilities

Optional Manual Override for increased safety

Optional IS - intrinsically safe control&feedback design is available

Digital Communication opitons by using Fieldbus interface cards such as HART, Foundation Fieldbus, Profibus, Pakscan, Modbus and RIRO

Used advanced technology for CVA (CVL and CVQ) range:

1. Dual Sensor technology - 2 pcs of independent position sensors (encoders) by 0,1% accuracy of sensing

2. User Interface - can communicate by free downloadable software and feedback e.g. test run measurments + Rotary selector on the top of actuator by STOP/ RUN/ TEST modes and by flashing LED in the centre of knob selector - by flashing Green/ Red/ Blue

3. Power Supply/ Fail to position - 100-240 VAC 1 phase or DC option; fail to safe mode by reserve powerpack consisted of supercapacitors

4. DC brushless motor - high efficency, brushless DC motor allows for maintenance free operation even by modulation duty

5. Hand Drive - Available both for part-turn or linear actuators

6. Terminal Bung Double sealing - double sealing inside terminal cover/ the 2nd line segregates the terminal from main enclosure so that water ingress is not possible/ As standard 4 pcs of conduit entries on each CVA

7. Geartrain - High efficiency spur gear drive by lifetime lubrication

8. Anti back-drive Mechanism - resistance against back-drive forces from the valve and up to 125% of rated force among normal condition

9.  Output Drive - CVL may be adapted for individual valves (not always confirm with ISO 5210/ 5211 or MSS SP-101/102

Rotork CVL -linear electric process control actuator:

Linear output drive suitable for linear valve adaptation

Continuous unrestricted S9 Class modulation duty

Standard on-board datalogger

Reserved power pack includes supercapacitors for storing enough energy for fail to safe operation

Travel rate: 38,1 - 50,8 mm 

Protection against overload/ precise switching both for position and thrust load/ output Speed can be set 

Output Speed is factory set by considering the optimum stroke time and thrust load for each application. Output speed can be set between 5-100 % of rated range

Further features:

Full Stroke-open cycle or PST is also can be performed 

Cycles (open/ stroke) are performed by using opto-isolated loop powered 4..20 mA control

Deadband between 0-10%; 0,1%-accuracy of increment

Damping- to reduce response to demand signal noise or instability

Signal Loss action: Close/ Stay put/ Open (lost signal means < 2 mA)

Output thrust by actuator can be set between 40..100% of rated thrust loads

CVA standard design resists any back-drive from the valve up to 125% of rated load of application

Valve-actuator characteristic: 

linear- standard by factory

equal percantage- can be set

quick opening - can be set 

custom set

Fieldbus-interface cards:

HART

Foundation Fieldbus

Pakscan

Modbus

RIRO 

Control & feedback:
