Solution

STANDARD-DD High Performance Damper Drives are the solution for Control of Combustion Air & Flue Gas thru a boiler.


STANDARD-DD is dedicated to assist our customers in providing resolutions.

Engineered for precise, accurate, dependable control for a wide variety of damper applications.


Rotary vane actuator - one moving part

  • Most reliable, efficient actuator design

Linear constant torque output for full 90° stroke

  • Output torques range from 90 ft. lbs. to 10,416 ft. lbs. (122 ot 14,312 Nm).
  • Master-Slave actuator option provides torque to 28,624 ft. lbs. (38,834 Nm).

Compact Rugged Design

  • Maximum environmental protection.

Wide range of input control & feedback options

  • Characterizable high-gain positioner with versatile signal conditions to interface with customers existing demand signal & feedback signals.

Durable corrosion resistant internal & external finish

High immunity to shock & vibration.


Damper Drives provide 100% duty cycle rating of 3600 starts per hour without overheating.

High Speed stroke times of three (3) seconds is available for full damper travel

No internal levers or gearing

  • Eliminates dead-band for fast response & sensitive control.

No dangerous external moving parts

  • Safe for operating & maintenance personnel

Designed for maintenance-free operation in harsh high temperature environments up to 300°F (149°C).

WARRANTY:

Three (3) years of (2) million cycles (4 million strokes), whichever occurs first, after date of shipment.

Inside Story

image19

HEART of the STANDARD-DD DRIVE SYSTEM

  1. Dual Opposed Lip Seals - Provides effective, air assisted seal for low friction & long, maintenance-free life.
  2. Steel Travel Stops - On both sides of steel vane
  3. Corrosion-Resistant Finish - Durable TGIC-Polyester Epoxy powder-coat finish inside & outside of actuator surfaces
  4. Steel Side-Plate Seal Retainer - Located on both sides of steel vane.  Provides the strength to assure accurate Open and Close stop positions
  5. Integral Namur Manifold - For direct-mount solenoid valve, eliminating fittings & tubing
  6. Alloy Steel Drive Shaft - High tensile output shafts for strength and durability.  ENP finish for corrosion-resistance.  Wrench Manual Override and Vane Position Indicator
  7. Integral Vane / Shaft Casting - Cast as a single piece; only one moving part.  Eliminates all "slop", hysteresis or lost motion
  8. Stainless Steel Seal Expanders- Located on both sides of steel vane.  Ensures long-term lip seal-to-case contact.  Excellent in both high-cycle and low-cycle applications.

image20

9. Stainless Steel Bolting Hardware - For long-term corrosion resistance

10. Bi-directional Travel Stops - 80° to 100° standard adjustments are stainless steel.  Extended travel stops available for reduced travel as low as 30° rotation

11. Large Air Inlet Ports on both sides of Actuator for Fast Operation- Provides for high-cycle speed of operation with no restrictions
12. Integral Namur Accessory Mount on outside top of Actuator Surface meets VDI/VDE 3485 accessory mount standards for positioners, limit switches and indicators
