1

Key Features

The 1" (DN25) size offers excellent flow rates while maintaining a manageable footprint for tight installations. It's ideal for both new builds and retrofit projects across a range of industries.
2

Key Features

These valves operate with a simple 90° turn, enabling fast shut-off in emergency or routine operations. This minimizes downtime and simplifies manual or automated control.
3

Key Features

Full bore models eliminate flow restrictions and reduce pressure loss across the valve. This makes them ideal for applications requiring maximum throughput and energy efficiency.
4

Key Features

Available in stainless steel, brass, PVC, and carbon steel, these valves are built to withstand corrosive, high-pressure, or high-temperature environments. The result is long-term reliability and lower maintenance costs.
5

Key Features

Choose from threaded, flanged, socket weld, or compression end connections for seamless integration into existing pipework. This flexibility ensures compatibility with a wide range of system designs.
6

Key Features

Many DN25 ball valves are available with ISO 5211 mounting pads, allowing for easy attachment of pneumatic or electric actuators. Perfect for integration into remote or automated process control systems.

Why Are 1" Ball Valves (DN25) Important?

1 inch Ball Valves (DN25) are important because they offer a perfect balance between compact size and high flow capacity, making them one of the most versatile and commonly used valve sizes in industrial and commercial systems. Their ability to handle a wide range of media—including water, gas, oil, steam, and chemicals—makes them suitable for countless applications across sectors like manufacturing, HVAC, agriculture, and processing.

These valves provide fast and reliable shut-off with a simple quarter-turn, ensuring quick isolation during maintenance or emergencies.

Frequently Asked Questions

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.
