Ball Valve

This size is commonly used in systems where increased flow capacity is needed without moving into bulkier pipe diameters. With a full-bore design and a simple quarter-turn mechanism, 1 1/4" ball valves offer a fast and effective method of isolating flow, making them suitable for everything from HVAC and utility lines to chemical transfer and process automation. Available in a wide range of materials—including stainless steel, brass, carbon steel, and PVC—these valves can be tailored to meet the demands of different pressure ratings, temperatures, and media compatibility.

Key benefits of 1 1/4 inch Ball Valves (DN32).

Key Features

These valves feature a full bore opening, allowing unrestricted flow and reducing pressure drop across the system. This makes them ideal for applications where maintaining flow efficiency is critical.

Key Features

The quarter-turn handle provides fast, simple open/close functionality with clear visual indication of valve status. This is particularly useful for manual shut-off in emergency or routine isolation scenarios.

Key Features

Available in stainless steel, brass, carbon steel, and PVC, DN32 ball valves offer excellent resistance to corrosion and chemical attack. This ensures a long service life even in harsh or aggressive environments.

Key Features

High-quality seats and seals provide a secure shut-off, even under pressure. This reduces the risk of system leaks and protects downstream equipment.

Key Features

Choose from threaded, flanged, socket weld, or compression end connections to suit your system design. This flexibility allows for easy integration into new or existing pipeline setups.

Key Features

DN32 ball valves can be fitted with electric or pneumatic actuators for automated flow control. This is ideal for process systems requiring remote operation, safety interlocks, or integration with control panels.

1 1/4" (DN32) ball valves play a crucial role in fluid control systems where a balance between compact size and high flow capacity is required. They offer a step up from smaller valves in terms of throughput, making them suitable for medium-duty applications in industrial, commercial, and process environments.

These valves are important because they combine ease of use with durability—thanks to their simple quarter-turn operation and robust sealing technology. Whether used for isolating sections of pipework, controlling chemical feed lines, or managing HVAC flows, DN32 ball valves provide a reliable shut-off solution that’s easy to maintain and versatile in application. Their availability in a range of materials and end connections also makes them adaptable to various media types and installation requirements, ensuring consistent performance across industries.

You would commonly find 1 1/4" (DN32) ball valves in medium-sized pipeline systems where reliable shut-off and efficient flow are essential. They’re widely used in commercial plumbing, HVAC systems, and industrial water treatment plants, where they manage fluid distribution, system isolation, and maintenance access points.

In chemical processing and manufacturing, DN32 ball valves are used for controlling the flow of aggressive or pressurised media, offering corrosion-resistant performance and easy automation options. You’ll also see them in agriculture and irrigation systems, compressed air setups, food and beverage processing, and cleaning-in-place (CIP) loops, where medium-volume flow control is needed with consistent reliability. Their versatility and adaptability make them a go-to choice across many sectors.

Whether it’s for a repair or a full system install, we’ll help you get it right the first time.

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.
