Choosing the correct butterfly valve is essential for guaranteeing long-term performance, safety, and cost effectivity in industrial piping systems. With so many different designs, materials, and linings available, knowing the application requirements is the first step in selecting the best option.
Think About the Media and Lining Needs.
If you deal with corrosive chemicals or acids or with ultra-pure fluids in your system, the PTFE Lined butterfly valve is usually the best choice. The chemical resistance of the PTFE lining is excellent and avoids contamination of media. For more demanding applications, the PTFE Lined Pinless Butterfly Valve provides even higher reliability by eliminating the danger of stem-pin corrosion and leakage and is suitable for severe services. Other options to the Handle PTFE Lined Butterfly Valve are available for easy hand operation, and theElectric PTFE Lined Butterfly Valve with accurate automated regulation for processing equipments. In tight spaces, the Small Size Ptfe Lined Butterfly Valve offers a seal zone for space-saving performance.
PTFE coating can be applied not only to butterfly valves but also to other valve types. The PTFE Coated Grooved End Butterfly Valve and the PTFE Coated Lug Butterfly Valve offer quick installation and excellent protection against corrosion. In the same way, PTFE Coated Ball Valves including PTFE Coated Thin Ball Valve, and PTFE Lined Check Valves featuring PTFE Coated Double Flanged Type Check Valves help you ensure dependable flow control over your applications.
Choose the Right Body Style and Connection Type
Butterfly valves are available in different connection types. Wafer Butterfly Valve is cost effective and used between two flanges, whereas the Lug Type Butterfly Valve enables one side pipeline removal lends itself to dead-end service. Flanged Type Butterfly Valve provides maximum strength for high pressure lines and Grooved Type Butterfly Valve allows easy, bolt-free installation. For the more specialized needs the Pinless Lug Type Butterfly Valve increases safety by eliminating through-stem pins, and Severe Service Double Flanged Butterfly Valve Robust Performance in Water Treatment and Power Plants.
Match Material to Operating Conditions
The choice of material has a direct effect on the life of the valve. Ductile Iron Flange Type Butterfly Valves and Ductile Iron Grooved Type Butterfly Valves are the cost effective solution for high strength, low temperature requirements for water and HVAC systems. For drinking water or weakly corrosive fluids, the Cast Iron Lug Butterfly Valve is a well-trusted solution. When increased corrosion resistance is needed, a Stainless Steel Flange Butterfly Valve is a strong candidate in the marine, food, and chemical industries. The PTFE Lined Cast Body Butterfly Valve With Gear Box combines the advantages of corrosion resistant lining with easy operation of the gear for big diameter. Manual Flange Type Butterfly Valve is used for Manual application setups and Rubber Coated Grooved Type Butterfly Valve for sealing at lowest cost in Non-Corrosive application.
End notes
When ordering a valve, please confirm the pressure rating, temperature range, actuator compatibility and applicable standards like AWWA, API or EN. Whether you are looking for a Pinless PTFE Lined Butterfly, a heavy-duty Lined Butterfly Valve, or any of the other options outlined above, matching valve design to system requirements will maximize uptime and minimize maintenance costs.
