The body - Is it better to have a stainless steel or spheroidal graphite iron butterfly valve?

Operational safety starts with the design, both large and small. It is therefore particularly important to us to always use only high-quality materials that enable long and trouble-free use. Every butterfly valve in a pipeline simply has to fit perfectly. That's why we rely on proven standards to protect your systems.

If there is a constant threat of corrosion due to external influences, your butterfly valve should be made of stainless steel (1.4408). Spheroidal graphite cast iron (GGG40), on the other hand, is recommended as a readily available, flexible sleeve, while spheroidal graphite cast iron (GGG50) impresses with its even higher strength. In extreme temperature or pressure regions, ASTM A216 WCB can also be extremely worthwhile. It's all in the mix.

The seal - What material should your sleeve be made of?

If you want to buy a functioning butterfly valve that complies with DIN in Germany, each individual part must fulfil its purpose. Especially with regard to the sealing materials used, the differences can be considerable. This is because, as the centrepiece of the valve, the sleeve is in permanent contact with sometimes very demanding media.

For this reason, we have a wide selection available for you:

• EPDM - typically used in water treatment or foodstuffs. However, due to its good resistance to vapours and chemical substances, it is also popular in specialist areas such as the aviation sector.
• NBR - our all-rounder for industrial butterfly valves in the moderate temperature range. Particularly recommended for (animal and vegetable) fats, oils or fuels, from diesel to petrol and lubricants.
• FPM and FKM (Viton) - designate the same material, sometimes internationally, sometimes in Germany, or as a separate brand. Often used for more aggressive media and can handle a wide range of chemicals or solvents.
• PTFE, RPTFE or PTFE with EPDM - almost without alternative in highly corrosive production facilities and therefore the standard in a wide range of industries, depending on the design. At Fergo, you will find PTFE-lined butterfly valves with actuator.
• INCONEL 718 - a nickel-based superalloy. Specific in its application, as it is approved up to the highest temperatures and pressures. Often seen in the oil and gas industry, the energy sector or even as a solution for the aerospace industry.

Manual, electric or pneumatic - which type of actuator for your butterfly valve?

In many industrial environments, it is crucial that the flow through a pipeline is not only controlled precisely, but also efficiently. An automated butterfly valve that can be actuated electrically or pneumatically therefore offers a number of advantages. Nevertheless, manual actuators still fulfil their purpose. We therefore have various models for you in our range.

So if you prefer direct control, you should take a closer look at the valves with an integrated hand lever or gearbox. For electric actuation, we can also recommend motors from the J4C series, which are as reliable as they are flexible. However, compressed air is often the method of choice, for example in potentially explosive atmospheres. Our pneumatic butterfly valves have actuators that are single-acting, spring closing and opening, or double-acting in both directions.
