• Design and Operation: Manual gate valves typically feature a handwheel that is connected to a threaded stem. Turning the handwheel causes the stem to move linearly, raising or lowering the gate to open or close the valve.
• Ease of Use: Manual operation is straightforward and does not require any external power source.
• Cost-Effective: Manual gate valves are generally less expensive compared to those with automated actuators.
• Reliability: Manual operation is less prone to failure due to power outages or mechanical issues.
• Design and Operation: Manual globe valves also feature a handwheel connected to a threaded stem. Turning the handwheel causes the stem to move linearly, raising or lowering the disc to control the flow.
• Ease of Use: Similar to gate valves, manual operation is straightforward and does not require any external power source.
• Cost-Effective: Manual globe valves are generally less expensive compared to those with automated actuators.
• Reliability: Manual operation is less prone to failure due to power outages or mechanical issues.
• Design and Operation: Handwheel drive gate valves feature a handwheel that is connected to a geared mechanism, allowing for easier operation with less physical effort. The geared mechanism can be designed to reduce the number of turns required to open or close the valve.
• Ease of Operation: The geared mechanism reduces the physical effort required to operate the valve, making it suitable for applications with frequent valve operation.
• Control Options: Handwheel drives can be designed to provide more precise control over valve operation.
• Integration: Handwheel drives can be integrated with position indicators and other control devices for better monitoring and control.
• Design and Operation: Handwheel drive globe valves also feature a handwheel connected to a geared mechanism, allowing for easier operation with less physical effort. The geared mechanism can be designed to provide precise control over the valve's disc position.
• Ease of Operation: The geared mechanism reduces the physical effort required to operate the valve, making it suitable for applications with frequent valve operation.
• Control Options: Handwheel drives can be designed to provide more precise control over valve operation.
• Integration: Handwheel drives can be integrated with position indicators and other control devices for better monitoring and control.
