Kelebihan Teknikal Kritikal
-
High-Torque Gear Multiplication: The 1077 transmits power from the handwheel through an input shaft to a worm and drive sleeve gear (sector). This gear set multiplies the input torque, enabling the smooth operation of large rotary valves that would otherwise be difficult to move manually.
-
Direct Splined Connection: The drive gear sleeve features a splined bore that mates directly with the splined valve shaft or stub shaft. This direct-drive design reduces the number of required parts, eliminates mechanical slop (deadband), and simplifies both installation and routine maintenance.
-
Intuitive Operation and Safety: To ensure safe and correct operation, the handwheel is clearly marked with the rotation direction required to open the valve. When installed according to factory instructions, clockwise handwheel rotation consistently closes the valve in all applications, reducing the risk of operator error.
-
High-Visibility Position Indication: The 1077 includes a bold rotation indicator with distinct markings for the fully open and fully closed positions. Incremental lines between these points provide the operator with accurate feedback for manual throttling throughout the 90-degree travel range.
-
Adjustable and Lockable Travel Stops: Accurate valve positioning is maintained by adjustable travel stops. These stops can be locked in place to establish precise 0-degree (closed) and 90-degree (open) limits. Additionally, stops for 60-degree operation can be used to set custom closing angles, protecting internal valve components from over-rotation.
-
Durable Gear Housing: The worm and sector gear mechanism is housed in a rugged enclosure, protecting the critical drive components from industrial contaminants and ensuring long-term reliability in harsh environments.
