A worm gear butterfly valve is a butterfly valve that installs a worm gear on the valve body. By rotating the handwheel on the turbine head, the butterfly valve can be opened and closed. The advantage of turbine drive is that it is very labor-saving, and the larger the diameter of the butterfly valve, the more advantages it can achieve with turbine drive. Common materials for worm gear butterfly valves include gray cast iron, ductile iron, cast steel, stainless steel, and alloy.

The worm gear butterfly valve uses different materials and can adapt to different working conditions and environments. So if you insist on which material is better, it is stainless steel. Stainless steel worm gear butterfly valves have stronger adaptability, but the cost is also the highest. In some ordinary operating environments, using stainless steel worm gear butterfly valves can actually increase costs

Generally speaking, when passing through medium such as water, steam, and oil at room temperature and low pressure, using gray cast iron or ductile iron materials for worm gear butterfly valves is the most suitable

If the material used is high-temperature and high-pressure, such as steam, high-temperature liquid, etc., it is suitable to use cast steel worm gear butterfly valves

Stainless steel worm gear butterfly valves are best used in corrosive liquid media, such as hospital wastewater and chemical plants. Additionally, stainless steel worm gear butterfly valves are used in the food industry

The worm gear butterfly valve made of aluminum alloy material can only be used in air conditioning water systems due to its anti condensation function. And with the continuous optimization of ductile iron butterfly valves, they have begun to replace the position of aluminum alloy butterfly valves in the air conditioning water system.
