Description
Handwheel Manual Override
Pneumatic actuator hand wheel operating box main purpose:
The handwheel mechanism is used in combination with a pneumatic device for opening a 90° butterfly valve, ball valve, etc., for manual or pneumatic driving.
Pneumatic hand wheel operating box features
※ Product serialization, the output torque is matched with pneumatic devices and valves.
※ Small in size, light in weight, reasonable in design and novel in style;
※ Pneumatic and manual. Rotate the eccentric 180° and the handle is in the manual (ON) position for manual operation. The handle is located in the pneumatic (OFF) position and is pneumatically operated.
※ The worm wheel connection inner hole is made of two key grooves separated by 90°, so that the user can select the position of the device opposite to the valve body as needed.
※ The product is equipped with special grease. After assembly with the valve, it is sealed, dustproof and waterproof. The protection grade is IP65.

FAQS
What is Handwheel Manual Override?
Handwheel Manual Override is a tool used to help operators gain mechanical control of automated machinery. It provides users with precise control over the pneumatic actuator or valves used in motion control applications, allowing them to manually bypass process controllers and manipulate equipment directly.
This type of manual override system has a wide variety of potential uses across multiple industries, from manufacturing to industrial production. In general, it works by installing an external hand wheel that can be turned independently of any existing electrical systems already in place. This hand wheel is then connected directly to the device’s internal gear ratio, enabling direct manipulation by the user while keeping all other controls intact and operational.
The main benefit offered by Handwheel Manual Override systems is convenience – they provide operators with quick access to manual interventions when needed without having to remove power or trip specific circuits within their facility’s electrical infrastructure. Additionally, this type of system ensures increased safety for workers due to its ability to quickly deactivate processes while also limiting any possibly hazardous consequences from incorrect handling using sophisticated sensors and limit switches included in its design.
What is manual override actuator?
A manual override actuator is a device designed to allow operators of industrial or commercial equipment the ability to manually control potentially dangerous operations, when needed. Manual override actuators provide a measure of safety by providing an easily accessible and reliable method for overruling automated responses or processes that may not be in line with the user’s expectations. It can also take over from an automated process if it malfunctions or encounters unexpected conditions that might otherwise cause significant damage.
Manual override actuators are used in many applications in various industries, including water treatment plants, food processing facilities and oil refining systems. These types of manual overrides are often found on valves, pumps, compressors and other machines where quick access to manual operation is necessary for safety purposes or during maintenance operations. The actuating mechanisms used will vary depending on the application; some common examples include levers, push buttons/switches/plungers or motorized mechanical devices such as chains/cables/belts and rollers which operate mechanically-actuated links.
How does a Handwheel Manual Override?
A handwheel manual override is a component of an automated system that allows for human control of the machine or process. It works by providing a mechanical force to disengage the automatic control and prevent it from controlling the machine. This is beneficial in cases where there are sudden power outages, when an operator needs to take over a process due to emergency conditions, or if manual adjustments are needed on irregular intervals.
