12 inch Gate Valve
DN300 gate valve, as a common fluid control device, its weight is one of the important indicators that users focus on when making a purchase.
The weight of a 12″ gate valve is affected by various factors such as material, structural design, pressure rating, and whether it has attachments. Based on market research and professional materials, the weight of a 12″ gate valve generally ranges from several hundred kilograms to several tons. Specifically, for a common 12″ gate valve made of cast iron or cast steel, its weight is usually around several hundred kilograms. However, if stainless steel or alloy steel, which are more durable and corrosion-resistant, are used, and higher pressure rating requirements are met, the weight may increase to several tons. Therefore, when making a purchase, users need to determine weight range of the gate valve according to specific needs and working conditions.
Main features of 12 inch gate valve.
- The wedge of 12 inch gate valve is ground to a mirror surface before assembly to ensure that it fits tightly with the seat ring and does not get stuck;
- The valve stem sealing is realized by the collaboration of flexible and woven graphite, ensuring a more reliable tightness;
- The12 inch gate valve has a good sealing performance at high temperature, and a wedge valve is not easy to jam after heating. Suitable for steam, high-temperature oil, oil, gas, and other media, as well as frequent switching components.Not suitable for easily coking media.

The application of 12 inch gate valves mainly includes the following aspects:
- Fire protection system: Gate valves are widely used in fire protection systems, mainly for cutting off or connecting the flow of media.
- Water supply and drainage system: In the water supply and drainage systems of the construction industry, gate valves are widely used to control the opening and closing of the water flow.
- Energy industry: In fields such as oil and gas, petrochemicals, and thermal power generation, gate valves are used to control the flow rate of liquids or gases.
- Chemical industry: During the chemical production process, gate valves are used to regulate the flow rate, pressure, and temperature of gases and liquids.
- Food and pharmaceutical industry: In the food and pharmaceutical fields, gate valves are used to monitor and control the flow rate, temperature, and pressure during the production process.
What are the different size of gate valve?
Gate valves have various sizes. Common sizes include DN15, DN20, DN25 in metric units, corresponding to 1/2 inch, 3/4 inch, 1 inch in imperial units. Larger sizes like DN300 (12 inches), DN600 (24 inches) are also widely used in industrial applications. The specific sizes available may vary by manufacturer and application requirements.
