300MM Butterfly Valves Wafer Pattern DN300

A 300MM Butterfly valve consists of a disc rotating in trunnion bearings. In the open position, the disc is edge-on, offering minimum resistance to flow. In the closed position, it is rotated against a seat. Butterfly valves are available in sizes from DN32-DN3000 (l 1/4" in to 120") diameter and include the popular 300MM butterfly valves. They are particularly attractive because they take up little more room than the pipe flanges. In fact some butterfly valves are designed specifically for insertion between pipe flanges, using through bolts. These are known as wafer butterfly valves. Other types are normally single-flanged or double-flanged, known also as lug-body valves.

Key Features & Benefits Of The DN300 TTV 300MM Wafer Pattern Butterfly Valves
1

Key Features

Low operational torque reduces the costs of actuation with low friction contact extending the life of the self cleaning seal. Replaceable seals offer flexibility and cost effective solutions without the cost of a complete new valve. Reducing lead times and unnecessary downtime for End Users.

Key Features

Hand polished, streamlined discs produce a much greater Cv than other butterfly valves on the market resulting in low pressure drops and reduced energy costs while maintaining a bi-directional bubble tight seal in the closed position.

Key Features

Actuated Butterfly Valves are an innovative solution for any company looking for a more efficient way to control fluid flow in their industrial processes. These TTV Butterfly Valves have been designed with two components that work together to provide perfect sealing capabilities.

Where are 300mm (DN300) wafer pattern butterfly valves typically used?

DN300 wafer butterfly valves are commonly installed in large-scale pipeline systems where high flow rates need to be managed efficiently. You’ll typically find them in water treatment plants, HVAC systems, district heating networks, chemical processing facilities, and general industrial operations.

Their compact wafer design allows them to sit neatly between flanges without adding unnecessary weight or space, which is especially important in larger pipework where installation and handling can become more challenging. They are also widely used in infrastructure projects such as pumping stations and distribution networks, where reliable shut-off and flow control are essential.

Why are DN300 wafer butterfly valves important in these systems?

These valves play a key role in controlling and isolating flow in larger pipelines while keeping systems efficient and easy to maintain. Their design offers a strong balance between performance and cost, providing effective sealing and low operating torque even at larger diameters like 300mm. This makes them easier to operate, whether manually or via actuation, and reduces strain on equipment over time.

In addition, their ability to handle both isolation and throttling duties makes them highly versatile, helping operators maintain consistent flow control, minimise downtime, and ensure the overall reliability of the system.

Power Control at DN300 Scale

Built for large pipeline performance, DN300 wafer butterfly valves deliver reliable flow control, strong sealing, and efficient operation where it matters most.
