◆ Product Overview: 

 The manual mechanism is a device used for manual operation of valves and other equipment, which is usually used as a backup means of operation for electric or other automatic control methods to ensure reliable operation of the equipment when the automatic control fails or requires manual intervention. 

 ◆ Working principle: 

 The working principle of the manual mechanism is based on the principle of mechanical transmission. When the operator turns the handwheel, the rotational force of the handwheel is transmitted to the parts connected to the equipment through the transmission mechanism, such as the valve stem or other actuators, thus driving the equipment to perform the corresponding action. For example, in the gate valve, the rotation of the handwheel makes the valve stem move up and down through the transmission mechanism, which in turn drives the gate plate to rise and lower, and realizes the opening and closing operation of the valve. 

 ◆ Performance characteristics: 

 - Easy to operate: The operation of the equipment can be realized by simply turning the handwheel, without complex operation skills and professional knowledge. 

 - High reliability: As a backup means of operation, the manual mechanism usually has a relatively simple structure and less dependence on electronic components and complex control systems, so it has high reliability in harsh environments or emergencies. 

 - Strong applicability: Manual mechanisms of different types and specifications can be designed according to the requirements of different equipment and working conditions to meet the manual operation needs of various valves, actuators and other equipment.

Each process, each facility, and each environmental constraint has its own special requirements. As a result, Kinko offers a comprehensive range of products that include different performance levels, pressures, functions and materials.
