Butterfly Valves

Butterfly valves are the most widely used control elements in piping systems, thanks to their compact design and economical structure, controlling flow with a circular disc that rotates around a central shaft. ORFA Industrial offers a wide range of butterfly valve series from stock, providing high sealing performance from heating-cooling lines to chemical processes. Professional butterfly valves, distinguished by their low weight and rapid open-close capabilities, ensure reliable flow management in large-diameter pipelines with the ORFA guarantee.

What are Butterfly Valves and Their Usage Advantages

Butterfly valves are space-saving mechanical devices that control fluid through the position of a disc (clapper) with a 90-degree rotation. Occupying much less space compared to gate valves, these butterfly valves are preferred especially in large-diameter lines for their cost-effectiveness and ease of installation. ORFA Industrial recommends the use of high-performance butterfly valves in water treatment plants, HVAC systems, and general industrial lines. Thanks to disc and seat (liner) material options, these butterfly valves fully adapt to many different fluid types, from aggressive chemicals to drinking water. Professional butterfly valves, with low pressure losses and structures suitable for actuator mounting, are the most efficient components of modern automation systems.

Types and Designs of Butterfly Valves

Different butterfly valve models are available based on connection type and operating principle. The main product groups in ORFA's inventory are:

Choosing the Right Butterfly Valves

The efficiency of your installation depends on selecting the correct butterfly valves based on fluid temperature, pressure class, and seat compatibility (EPDM, NBR, Viton, PTFE). Wrong seat selection can lead to early loss of sealing and disc locking on butterfly valves. With ORFA engineering expertise, we determine the most durable butterfly valve configuration for your project, guaranteeing sealing with 100% tested products. Modern designed butterfly valves, equipped with gearboxes (handwheels) or electric/pneumatic actuators, increase control precision. High-strength professional butterfly valves promise long operational life thanks to their low torque requirements. Investing in quality butterfly valves is vital for the operational safety and maintenance costs of large facilities.
