Inside Story
HEART of the STANDARD-DD DRIVE SYSTEM
- Dual Opposed Lip Seals - Provides effective, air assisted seal for low friction & long, maintenance-free life.
- Steel Travel Stops - On both sides of steel vane
- Corrosion-Resistant Finish - Durable TGIC-Polyester Epoxy powder-coat finish inside & outside of actuator surfaces
- Steel Side-Plate Seal Retainer - Located on both sides of steel vane. Provides the strength to assure accurate Open and Close stop positions
- Integral Namur Manifold - For direct-mount solenoid valve, eliminating fittings & tubing
- Alloy Steel Drive Shaft - High tensile output shafts for strength and durability. ENP finish for corrosion-resistance. Wrench Manual Override and Vane Position Indicator
- Integral Vane / Shaft Casting - Cast as a single piece; only one moving part. Eliminates all "slop", hysteresis or lost motion
- 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.
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
