Application scenarios
On-site manual isolation for resilient-seated or rubber-lined quarter-turn valves
For on-site manual operation and line isolation of resilient-seated or rubber-lined quarter-turn valves. Available with a standard handle, 10-position notch plate, and open/close stop device for valve sizes from 1 inch to 12 inches (25 mm to 300 mm).
On-site manual operation and isolation for high-pressure quarter-turn valves
For on-site manual operation and isolation of high-pressure quarter-turn valves. This series is equipped with a high-torque handle, 9-position notch plate, and open/close stop device for high-pressure valves in sizes from 2½ inches to 8 inches (65 mm to 200 mm).
Manual throttling for compatible quarter-turn valves
For manual throttling service of compatible quarter-turn valves. This series is specifically suitable for on/off and throttling applications, with valve position indexing via a notch plate and an optional infinite-position quadrant plate.
Selection points
Two Handle Versions Matched to Valve Type
Available with standard and high-torque handles: the standard handle is suitable for 1-inch to 12-inch (25mm to 300mm) resilient-seated valves, while the high-torque handle is suitable for 2½-inch to 8-inch (65mm to 200mm) high-performance valves.
Standard Multi-Position Notched Indexing Configuration
The actuator uses a handle with a locking spring and a bolted notched plate. Resilient-seated valves are standard with a 10-position quadrant plate, while high-performance valves are standard with a 9-position quadrant plate, suitable for on/off and throttling service.
Open/Close Stops Prevent Over-Rotation
Both resilient-seated valve and high-performance valve versions are equipped with open/close stop devices to limit excessive valve rotation, suitable for isolation and on/off applications.
Optional Infinite-Position Quadrant Plate
An optional infinite-position quadrant plate provides more flexible opening-position selection for manual throttling applications than standard 9-position or 10-position quadrant plates.
Optional Memory Stop and Misoperation Prevention Accessories
Optional memory stop devices, padlock kits, and 2-inch square nut versions are available to meet site-specific opening control and operational management requirements.
Optional 180° Notched Plate
An optional 180° notched plate is available as a quadrant plate configuration option for Series 01 manual actuators.
Installation & maintenance notes
Match Valve Type, Size, and Handle Version
Before installation, select the appropriate handle version according to valve type and size: use the standard handle for 1-12 inch resilient-seated valves and the high-torque handle for 2 1/2-8 inch high-performance valves.
Verify Quadrant Plate Positions and Valve Type
During installation, verify that the quadrant plate positions match the valve type: resilient-seated valves are standard with 10-position quadrant plates, while high-performance valves are standard with 9-position quadrant plates.
Confirm Open/Close Stops Prevent Over-Rotation
Before installation and operation, confirm that the open/close stop devices function properly to prevent excessive valve rotation.
FAQ
What is the operating principle of the Series 01 manual actuator?
The Series 01 manual actuator provides manual on/off and throttling control through a quarter-turn mechanism. Rotational movement drives the notch plate position indicator to display the current status, providing open/close and positioning functions.
How does compatibility differ for various valve sizes in this series?
Resilient-seated valves are suitable for sizes from 1"-12" (25mm-300mm), while high-pressure valves are suitable for sizes from 2 1/2"-8" (65mm-200mm); both use different notch plates for positioning.
What common optional control features are available?
Available options include an infinite-position notch plate, 180° slotted plate, memory stop device, padlock kit, and 2" square nut version.
What are the main applications of this manual actuator?
It is used for isolation, on-off, and throttling control applications, and is suitable for manual actuation of resilient-seated and rubber-lined seat valves.
What key points should be considered during maintenance and installation?
Check the locking spring, readability of the direction indicator, and protection against over-rotation of the notch plate during opening and closing. Also ensure that the bolted slotted plate is securely fastened and follow standard equipment maintenance procedures.
