Pneumatic mechanical valves and pneumatic hand control valves are both types of valves used in pneumatic systems, but they serve different purposes and are operated in different ways.
Pneumatic Mechanical Valve:
These valves are operated automatically by mechanical means, such as springs, levers, or cams.
They are commonly used in industrial applications where precise control or automation is required.
Mechanical valves are often used in conjunction with pneumatic actuators to control the flow of compressed air in a system.
Examples include ball valves, butterfly valves, and diaphragm valves.
Pneumatic Hand Control Valve:
These valves are operated manually by hand, usually through the use of a lever, knob, or push-button.
They are often used for manual control of pneumatic systems, such as opening and closing air lines or regulating pressure.
Hand control valves are simple to operate and are commonly found in various pneumatic tools and equipment.
Examples include ball valves, gate valves, and globe valves with manual actuators.
In summary, pneumatic mechanical valves are operated automatically by mechanical means, while pneumatic hand control valves are operated manually by hand. The choice between the two depends on the specific requirements of the pneumatic system and the desired level of automation or manual control.
