12 inch Butterfly Valve
The 12 inch butterfly valve dimensions is 12 inch, and in DN it is DN300.
The standard dimensions of butterfly valves are usually determined as per international standards or industry standards. The following are the standard dimension ranges of some common butterfly valves:
- Small-sized butterfly valves: The diameter is generally between DN50 (2 inches) and DN300 (12 inches), which are suitable for pipeline systems with a small flow rate.
- Medium-sized butterfly valves: The diameter ranges from DN350 (14 inches) to DN600 (24 inches), and they are suitable for pipeline systems with a medium flow rate.
- Large-sized butterfly valves: The diameter exceeds DN600 (24 inches) and can be customized according to actual needs. They are used for fluid control tasks that handle large flow rates.
About the 12 inch butterfly valve:
- It has no dead zone design;
- It has live loaded packing system design;
- It has fire protection structure design;
- It has double safety sealing design.

The 12 inch butterfly valve mainly used in the following fields:
- Industrial pipeline systems: in industries such as chemicals, petroleum, and natural gas, 12 inch butterfly valves are used to control various corrosive or non-corrosive chemical fluids, such as strong acids and alkalis like sulfuric acid, hydrochloric acid, and sodium hydroxide, as well as the transportation and flow regulation of various organic solutions, ensuring the stability and safety of the production process.
- Water treatment systems: in water treatment plants and sewage treatment plants, they are used for the intake of raw water, the control of water flow during the purification process, and the adjustment of the transportation volume of clean water and sewage, meeting the needs of urban water supply and sewage treatment.
- Ventilation and air conditioning systems: in commercial buildings and industrial plants, these valves are used to regulate the ventilation volume and the water flow in the air conditioning system, ensuring the freshness and comfort of the indoor air, and at the same time achieving energy-saving operation.
- Fire protection systems: in fire hydrant pipelines and automatic sprinkler fire extinguishing systems, they are used to control the flow of fire-fighting water, ensuring that an adequate water source can be quickly provided in case of a fire to extinguish the fire and control the spread of the fire.
- Shipbuilding and ocean engineering: in the bilge water system and seawater cooling system of ships, they are used to control the discharge of bilge water and the flow of seawater, ensuring the normal operation of equipment and the cooling effect.
- Food and beverage industry: during the production of beverages and food processing, 12 inch butterfly valves are used to control the flow of raw materials such as water, juice, edible oil, and milk, ensuring the quality and taste of the products.
- Environmental protection and flue gas treatment: in the flue gas desulfurization and denitrification systems of thermal power plants and steel plants, 12 inch butterfly valves are used to control the flow of desulfurizers and denitration agents, ensuring that the flue gas is discharged up to standard.
How much does a 12 butterfly valve weigh?
The weight of a 12 inch butterfly valve can vary depending on its material, type, and manufacturer. Generally, a 12 inch butterfly valve made of cast iron might weigh around 50 to 80 kilograms, while one made of stainless steel could weigh 60 to 100 kilograms or more. For a more accurate weight, it’s best to refer to the product specifications provided by the manufacturer.
