Firstly, in terms of execution, manual butterfly valves have many advantages:

Low cost, compared to electric and pneumatic butterfly valve, manual butterfly valves have a simple structure, no complex electric or pneumatic devices, and are relatively inexpensive. The initial procurement cost is low, and maintenance is also relatively simple, with low maintenance costs.

Easy to operate, no external power source required, can still operate normally in special situations such as power outages, and the operation of opening and closing is easy to master without complex training.

High reliability, manual wafer butterfly valve do not have electrical components or complex pneumatic parts, reducing the risk of valve failure due to electrical or pneumatic system failures. Its simple structure makes it highly reliable and stable.

Manual butterfly valve include handle mode and turbine mode. So, what are the main differences between handle clamped butterfly valves and worm gear clamped butterfly valves?

1. Operation method:

The handle wafer type butterfly valve is manually operated directly through the handle. This method is simple and direct to operate, and the butterfly valve can be opened and closed by turning the handle. It is generally used for pipeline systems with smaller diameters, lower pressures, and not requiring extremely high operating accuracy.

The worm gear clamped butterfly valve is driven by a worm gear mechanism. This driving method can achieve more precise control and can finely adjust the opening of the butterfly valve. Usually suitable for pipelines with larger diameters or requiring fine flow control.

2. Torque

The handle clamp butterfly valve relies on manual torque, which is relatively small, so it may be difficult to open or close in some working conditions that require a large torque.

The worm gear clamped butterfly valve can amplify torque through worm gear transmission, making it easier to operate large butterfly valves.
