Weld Neck Flange for Butterfly Valve EN 1092-1

At UTMK, you can order a Weld Neck Flange for Butterfly Valve, specifically engineered to create reliable, leak-proof connections in critical piping systems. Unlike standard flat flanges that can obstruct the valve's disc, this component ensures unimpeded operation and prevents fugitive emissions, making it essential for the integrity and efficiency of your industrial network.

Technical Characteristics

Our weld neck flanges for butterfly valves are manufactured from high-quality steel grades and conform to key international standards, ensuring full compatibility and operational reliability.

Advantages of Weld Neck Flanges for Butterfly Valves

Utilizing these specialized flanges not only ensures correct installation but also delivers the long-term system stability required to de-risk operations and maintain process continuity.

• De-Risk Your Operations. Engineered specifically for butterfly valves to eliminate disc interference and ensure a bubble-tight seal, preventing costly leaks and unscheduled downtime that can disrupt your entire supply chain.


• Assured Technical Compliance. Manufactured in strict accordance with EN 1092-1 standards from S235JRG2 steel, our flanges are fully certified under our ISO 9001:2015 Quality Management System, providing the documentation you need for regulatory approval.


• Enhanced ESG & Supply Chain Security. Our flanges offer full material traceability and quality assurance, helping you meet stringent sustainability reporting standards and fortifying your supply chain against component failure.


• Superior Structural Integrity. The weld-neck design provides a high-strength, butt-welded connection that withstands greater pressure, vibration, and stress compared to slip-on alternatives, ensuring long-term system reliability in demanding environments.

Spheres of Application

These specialized flanges are an indispensable component for installing butterfly valves across a wide range of industries and applications.

• Industrial Applications


• Oil & Gas, Chemical Processing, and Power Generation: For connecting valves and equipment in medium-pressure pipelines (compliant with EN 1092-1).


• Waterworks and Municipal Utilities: Essential for installing shut-off valves in water treatment plants, distribution networks, and wastewater systems.


• Marine and Shipbuilding: Used in piping systems where high strength and resistance to vibration are critical for safety and performance.


• HVAC and Industrial Cooling Systems: For reliable connections of large-diameter pipes and control valves.


• Practical Examples (SME):


• Fabrication of custom process skids for fluid handling.


• Assembly of high-pressure pumping stations and irrigation systems.


• Connecting valves to tanks, vessels, and other process equipment.


• Repair and maintenance of industrial piping where a robust, permanent connection is required.
