The document details the construction and materials of various parts, such as indicators, pistons, and bearings, made from materials like engineering plastics, stainless steel, and aluminum alloy.
The document explains the operating principles of double-acting and spring-return actuators, detailing how compressed air and springs drive piston movement and output shaft rotation.
The JHA series actuators are noted for their high quality, low friction, and long life, with output torque ranging from 8Nm to 10000Nm. They operate under various temperature conditions and comply with IEC61508 and other standards.
The actuators are designed to comply with NAMUR and ISO5211 standards for easy installation and compatibility with accessories.
The document provides detailed tables of output torque for both double-acting and single-acting actuators across different models and air pressures.
Guidelines for selecting the appropriate actuator model based on valve torque and safety factors are provided, along with ordering codes and dimensions for various models.
- Output Torque: Lists output torque values for different models at various spring pressures and angles.
- Dimensions and Weight: Provides detailed dimensions and weight for models, including air volume for opening and closing.
- Consider the safety torque, which is the valve torque plus a safety factor (30-50%).
- Factors affecting torque include air supply pressure, actuator type, rotation, fail mode, and valve operating conditions.
- Safety values vary based on the medium and should be added to the valve torque.
- Air Stroke: Describes how air pressure affects piston movement and torque output.
- Spring Stroke: Explains torque output when air is lost and springs restore the actuator.
- Includes details on pneumatic actuators, solenoid valves, signal feedback, positioners, and special customizations.
- Operating temperature ranges and connection sizes are specified.
- Details on the JHM series manual override gear operator, including materials, dimensions, and torque specifications.
- Features include a totally-sealed box, stroke limits, and safety control functions.
- Outlines various models of actuators and connecting shafts, specifying dimensions and types of holes.
- High strength cold forging steel is used, providing super impact resistance.
- Customization for special sizes is available.
- Double Acting Actuator: Controls valve opening and closing.
- Single Acting Actuator (Spring Return): Automatically closes or opens the valve when air or power is cut off.
- Double Control Solenoid Valve: Opens the valve when one coil is energized and closes it with the other coil, featuring a memory function for explosion-proof applications.
- Limit Switch Box: Monitors and signals the valve's open/closed status, suitable for explosion-proof environments.
- Mechanical Positioner: Controls valve medium flux based on air pressure, also explosion-proof.
- Intelligent Positioner: Uses control software to manage pneumatic actuator intake and exhaust, driving the valve to a set position.
- Clutch Type Manual Valve Actuator: Allows manual operation for valve control during air or power loss.
- Provides ordering codes for adaptors and hole types, with 'F' indicating square holes, 'WD' for flat holes, and 'K' for round holes with keyway.
- Includes a list of internal adaptor specifications with dimensions for various models.
- Highlights professional achievements and technology advancements by JUHANG, emphasizing their role in creating the future.
