Ball Valve

Our 12" Ball Valves (DN300) are designed for heavy-duty industrial applications where maximum flow capacity and robust shut-off are essential. These large-diameter valves are ideal for handling high volumes of liquids or gases with minimal pressure drop, thanks to their full-bore design. Whether used in water treatment plants, oil and gas pipelines, power generation facilities, or large-scale process systems, DN300 ball valves provide long-lasting performance under demanding operating conditions.

Key features and benefits of 12 inch Ball Valves (DN300).

Key Features

The full bore design ensures maximum flow capacity with minimal pressure drop, making it ideal for high-volume systems. This allows fluids or gases to pass through unrestricted, improving system efficiency

Key Features

Manufactured from durable materials like stainless steel or carbon steel, these valves are built to handle high pressure and harsh environments. Their robust body structure ensures long-term reliability even under continuous operation.

Key Features

Standard flanged ends provide secure, leak-proof connections and easy integration into large pipeline networks. This design simplifies installation, maintenance, and future upgrades.

Key Features

Available with ISO mounting pads, these valves can be easily fitted with electric or pneumatic actuators. This enables remote control and automation, ideal for large-scale industrial operations.

Key Features

With high-quality internal components and protective coatings, DN300 ball valves are designed to resist corrosion, abrasion, and chemical attack. This extends the service life in aggressive media environments.

Key Features

Optional fire-safe designs and anti-static devices enhance safety in critical applications. These features provide added protection in hazardous or high-risk areas such as oil, gas, and chemical processing.

12 inch Ball Valves play a vital role in high-volume, large-diameter pipeline systems where reliable flow isolation and minimal pressure loss are essential. In industries such as oil and gas, water treatment, chemical processing, and power generation, these valves control the movement of large quantities of media with precision and safety. Their full bore design allows for unrestricted flow, which is crucial in systems where efficiency and throughput directly impact productivity and operational cost.

The robust construction of DN300 ball valves ensures durability in extreme pressure and temperature conditions, reducing the risk of failure and unplanned downtime. With options for automation, fire-safe protection, and anti-static features, they are also critical for maintaining safety and compliance in hazardous environments. These valves are not just components—they’re central to the performance, safety, and long-term reliability of large-scale industrial infrastructure.

DN300 Ball Valves (12 inch) are commonly found in large-scale industrial systems where high flow rates and reliable shut-off are essential. In the oil and gas industry, they are used in pipeline isolation, transfer lines, and tank farm operations to control the flow of crude oil, natural gas, or refined products. Water treatment and wastewater plants use them to manage the distribution of clean water or the handling of effluent in high-capacity mains and filtration systems.

You'll also find DN300 ball valves in power generation facilities, particularly in cooling systems, steam lines, and fuel handling setups, where uninterrupted flow and durability are crucial. In the chemical and petrochemical sectors, these valves help manage large volumes of corrosive or hazardous media under demanding conditions. Whether in infrastructure, energy, or processing plants, 12" ball valves are essential for ensuring system control, operational efficiency, and safety in high-volume, high-pressure environments.

Industries

A ball valve is used to start or stop the flow of liquids or gases by rotating a ball with a bore inside the valve body. It provides quick, reliable shut-off with minimal pressure drop.

Ball valves use a hollow, pivoting ball that aligns with the flow path when open and rotates 90° to block flow when closed. The handle position clearly indicates whether the valve is open or shut.

Ball valves are not ideal for throttling or precise flow regulation, as partial opening can cause seat wear and turbulence. They're best used in fully open or closed positions.

Ball valves can be made from stainless steel, brass, bronze, PVC, CPVC, carbon steel, and other alloys. Material choice depends on the application, pressure, and media compatibility.

Yes, many industrial-grade ball valves are designed to handle high pressures, especially those made from metal with reinforced seals and full-bore designs.

Common types include two-piece, three-piece, flanged, wafer, full bore, reduced bore, and multi-port ball valves. Each type suits different installation and maintenance needs.

Ball valves have a long service life, especially in clean systems. With minimal moving parts and a durable seal, they often outlast other valve types when used correctly.

Most ball valves are bidirectional and allow flow in both directions. However, some designs may be unidirectional depending on the seat and body configuration.

Yes, ball valves can be fitted with pneumatic or electric actuators for remote or automatic control. This is common in industrial and process automation.

Ball valves are generally low maintenance. Three-piece designs are preferred where service or cleaning may be needed, as they allow in-line maintenance.

Ball valves are used across many sectors, including oil & gas, chemical processing, water treatment, food & beverage, pharmaceuticals, and HVAC systems.

Ball valves come in sizes ranging from 1/4" (DN08) for small systems to 12" or larger (DN300+) for industrial pipelines. Size selection depends on flow rate and pipe compatibility.
