TECHNOLOGY

  • Electricity is supplied everywhere

  • Safest and cleanest energy source

  • Corresponding:

    - power supply- signalling- proccessing of signalling

  • Lean maintenance

Electric

No pumps and compressors necessary!


CONSTRUCTION BASICS

  • Equipped with DC motors

  • Integrated limit switches

  • Integrated control devices

  • Full metal gears

  • Manual override at valve stem

  • All voltages possible

  • Technical upgrades

Content, competence, durability!


TA ACTUATORS

  • High torque output up to 1500 Nm

  • Compact size

  • Minimum external control efforts

  • Solid metal casing

  • Matching flow of torque

  • Numerous options available

Customized actuators for your valve!


EC Directive ATEX

Ex II 2G EEx d IIC T6

EXPLOSION PROOF ACTUATORS

  • Suitable for Zone 1 + Zone 2, equipment category 2G + 3G

  • Flameproof enclosure "d"

  • For gases with strongest ignition penetration "C"

  • Temperature Class T6 for gases withignition temp. > 85°C

  • Confirmed EC ATEX Directive and IECEx Scheme

  • Failsafe function on request

Safety for hazardous areas!


EMERGENCY-CONTROL-UNIT E71

  • Automatic valve-adjustment into safety position

  • Opening or closing in case of power failure

  • Mounted inside the actuator

  • Accumulators for back-up voltage

  • Maintenance-free

  • Charging unit

Failsafe device for all valve types!


FM SYSTEM

  • Patented Failsafe-System

  • Self-operating in all emergency cases

  • Operated by the force of a spring

  • No back-up voltage required

  • May be operated in any valve position

  • Extremely short operating time

Suitable for Butterfly-Valves and Ball-Valves!


APPLICATIONS FOR 100% HUMIDITY

  • Hermetic enclosure IP 68

  • Permanent underwater service

  • Coastal and off-shore areas

  • Extreme corrosive environments

  • Casing available in stainless steel

A casing that truly protects against intrusions!
