Valvcon

Valvcon Actuators

Key Features:

• Compact Design:
  • Space-saving, lightweight, and easy to mount on a variety of       valves.
• Robust and Reliable:
  • Designed for rugged environments with corrosion-resistant housings       suitable for harsh industrial conditions.
• Electric Operation:
  • Low maintenance compared to pneumatic or hydraulic actuators.
  • No risk of fluid leaks; environmentally friendly.

  • Digital communication capability (Fieldbus, Modbus, etc.)
• Manual Override:
  • Built-in manual override for emergency or maintenance scenarios,       allowing manual valve operation when power is lost or maintenance is       required.
• Fail-Safe Capability:
  • Battery-backup or capacitor backup to move valve to a safe position       in power-loss scenarios.
• Position Feedback and Indication:
  • Clear visual position indicators and integrated limit switches or       optional potentiometers for remote monitoring and precise valve       positioning.
• Ease of Installation and Setup:
  • Direct mounting to ISO-standardized valve interfaces.
  • Simplified wiring and setup procedures.
• Wide Range of Torque Ratings:
  • Available torque outputs suited to various valve sizes and       pressures.
• Low Power Consumption:
  • Energy-efficient motors minimize operating costs and reduce       environmental impact.
• Certification and Compliance:
  • Actuators certified according to       industrial standards (e.g., UL, CSA, CE, ATEX, IECEx for hazardous       locations).
• Weatherproof and Explosion-Proof Enclosures:
  • Suitable for outdoor       installation or hazardous areas with specialized enclosure ratings (e.g.,       NEMA 4/4X, IP67/IP68).
