With a quarter-turn operation for fast and easy shut-off, our 4" valves are available in a range of configurations—including flanged, threaded, and welded ends—to suit various installation requirements. They’re constructed from high-quality materials such as stainless steel, carbon steel, brass, and PVC, offering excellent resistance to corrosion, wear, and harsh media. Suitable for both manual and actuated systems, DN100 ball valves provide smooth operation and tight sealing, even under high pressure and temperature conditions.

Key features and benefits of 4 inch Ball Valves (DN100).

Key Features

The full-bore construction of DN100 ball valves ensures unrestricted flow, reducing pressure drop and maintaining system efficiency. This makes them ideal for high-volume fluid transfer and critical flow applications.

Key Features

Built from durable materials such as stainless steel or carbon steel, these valves are designed to withstand harsh conditions and aggressive media. Their solid construction guarantees long-term reliability in heavy-duty environments.

Key Features

With a simple 90-degree handle or actuator movement, the valve can be quickly opened or closed. This rapid shut-off capability is essential for emergency response and system control.

Key Features

Available with flanged, threaded, or welded ends, these valves can be easily integrated into a variety of pipeline systems. This flexibility allows for easier installation and compatibility with industry-standard pipework.

Key Features

High-quality seats and seals ensure bubble-tight shut-off, even under high-pressure or high-temperature conditions. This minimizes the risk of leakage, protecting equipment and reducing maintenance costs.

Key Features

4" ball valves can be operated manually or fitted with electric or pneumatic actuators for remote control. This makes them suitable for both simple installations and advanced automated systems.

4 inch (DN100) ball valves play a crucial role in large-scale industrial systems by offering fast, reliable isolation and high-flow capacity. Their full-bore design allows for maximum fluid transfer with minimal restriction, which is essential in maintaining efficiency across critical processes like water treatment, chemical distribution, and energy production. In systems where downtime or pressure loss can be costly, DN100 ball valves provide the performance and durability needed to keep operations running smoothly.

Their ability to handle high pressures, aggressive media, and frequent operation makes them a go-to solution in demanding environments. Whether operated manually or through automation, they offer safe, consistent control that supports everything from process safety to system integrity. For engineers, maintenance teams, and plant operators alike, these valves are a dependable component in managing high-volume fluid handling with confidence.

You would typically find 4" (DN100) ball valves installed in industrial and commercial systems where high-volume fluid handling is essential. They are widely used in water treatment plants for isolating main lines and controlling flow through filtration or pumping systems. In the oil and gas industry, DN100 valves are found on pipelines, loading systems, and processing units handling fuel, chemicals, or compressed gases.

They're also common in chemical plants, HVAC systems, and manufacturing facilities, where large pipe diameters require strong, reliable shut-off solutions. In district heating networks, power stations, and bulk material handling plants, 4" ball valves help maintain flow efficiency and system safety under varying pressures and temperatures. Whether it’s fluid transfer, media isolation, or process control, DN100 valves are built for environments that demand performance and durability on a larger scale.

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.
