Why Electric Butterfly Valves Simply Belong Today
Whether water treatment, chemical, food industry, or energy plants – it's not just about letting things through or throttling. Safety counts, repeatability, reliability. This is exactly what the electric butterfly valve delivers.
It regulates liquids, gases, or steam automatically and repeatably. No surprises, nothing left unclear. And especially when processes become more complicated – which happens constantly – the valve simply grows with them.
Ultimately, automation isn't about being an end in itself. Everyday work should become easier. That's exactly what happens here.
FERGO – Experience That Doesn't Have to Be Loud
FERGO has been dealing with valve automation for years – this shows not through big claims, but in the details. Wafer-type and lug-type butterfly valves with electric actuators are a fixed part of the offering.
Whether DVGW butterfly valves, stainless steel variants, or chemical-resistant types with PTFE lining – every electric valve is automated by experienced fitters and thoroughly tested before dispatch.
The standard multi-voltage actuators (24-240 V AC/DC) suit many applications. For special requirements, actuators from AUMA or DEUFRA are added, as single or three-phase variants. Always as it fits the system. When standard solutions aren't suitable, adaptations are made.
Features That Really Count in Everyday Life
When choosing the actuator, the medium, pressure, and of course a reasonable safety factor matter. The brushless motor drives the shaft via a gearbox. A position indicator (DOME) always shows where the valve currently is. Multi-colour LEDs show the operating status at a glance.
And also helpful:
- Manual override function, when it matters
- Flexible electrical connections for power supply, feedback, and control signals
- DPS positioner (4-20 mA or 0-10 V) for precise regulation
- BSR battery pack that moves the valve to the safety position in case of a power failure
The speed of movement can be adjusted – so nothing jerks and sensitive pipes are spared. And of course, integration into remote monitoring and data management systems also works. Maintenance work becomes plannable, failures rarer.
This is how technology needs to run today: It stays in the background – but it works.
Conclusion?
An electric butterfly valve has long been more than mere automation. It ensures stable processes, safe systems, and pretty relaxed everyday work. When the design and automation are right, you almost never think about it again – and that's perhaps the best praise a valve can ever receive.
Frequently Asked Questions – Butterfly Valves
FERGO carries a comprehensive range of butterfly valves to cover virtually every industrial and building services application. The main subcategories are:
- Fergo Butterfly Valves – Standard wafer and lug butterfly valves (AK200/AK201) in ductile iron GGG40 with stainless steel disc, available in EPDM, NBR, FKM/FPM, and PTFE seat materials, DN25 to DN1200, PN6/10/16 and ANSI Class 150.
- Stainless Steel Butterfly Valves – Full stainless steel body and disc for corrosive media, food, pharmaceutical, and outdoor applications.
- DVGW Butterfly Valves – Certified valves for potable water (W270) and natural gas applications, fully compliant with German and European standards.
- Electric Butterfly Valves – Automated valves with electric actuators for PLC integration, remote control, and building management systems.
- Pneumatic Butterfly Valves – Fast-acting automated valves with pneumatic actuators, including ATEX-rated options for hazardous areas, DN25 to DN1200.
- PTFE Butterfly Valves – PTFE-lined valves for aggressive acids, alkalis, solvents, and high-purity processes.
- Butterfly Valves with Gearbox – Manual handwheel operation for larger nominal sizes where lever operation is not practical.
- Double-eccentric Butterfly Valves – High-performance valves with metal sealing for higher pressures, temperatures, and demanding process applications.
Both designs mount between pipe flanges, but they do it differently. A wafer butterfly valve is clamped between two flanges using long through-bolts that pass through both flanges and the valve body. It is the more compact and economical choice and is ideal when you always want to isolate a full pipe section. A lug butterfly valve has threaded inserts (lugs) cast into its body. Each side of the pipeline bolts directly and independently into these lugs. This allows one side of the pipeline to be disconnected and removed while the other side remains pressurised – a configuration known as dead-end service. If you need maintenance flexibility or plan to work on sections of pipe without a full system shutdown, lug design is the better option. FERGO offers both designs across all its standard butterfly valve ranges.
The seat or liner is the heart of the butterfly valve – it is in direct contact with your medium and determines chemical compatibility and temperature limits. Here is a quick guide:
- EPDM – The all-rounder for water, hot water, steam, and mild chemicals. Resistant up to approx. 120 °C. Widely used in HVAC and building services. Not suitable for mineral oils.
- NBR (Nitrile) – Designed for mineral oil-based media such as hydraulic oil, fuels, and cooling lubricants. Good resistance to aliphatic hydrocarbons. Not recommended for hot water or steam.
- FKM / FPM (Viton®) – Excellent resistance to a wide range of aggressive chemicals, oils, and elevated temperatures. Suitable for more demanding industrial process applications.
- PTFE (Teflon®) – Near-universal chemical resistance. The first choice for aggressive acids, alkalis, and solvents. Also available as a full PTFE-lined valve – see PTFE Butterfly Valves.
Yes – if your application involves natural gas, liquefied petroleum gas (propane/butane), or potable drinking water, you are legally required to use valves that carry the relevant DVGW certification. FERGO's DVGW Butterfly Valves hold approvals under DVGW Gas (DIN EN 13774) and DVGW Drinking Water (W270), ensuring full compliance with German and European safety and material standards. These certified valves are available in both wafer and lug design, from DN25 to DN300, with PN6 to PN16 pressure ratings, and can be equipped with hand levers, gearboxes, electric actuators, or pneumatic actuators.
A centric (concentric) butterfly valve has its disc shaft running directly through the centre of the disc and the seat. When the disc closes, it rubs against the seat along the full rotation, which leads to some wear over time. This design is cost-effective and perfectly suitable for standard industrial and building services applications at moderate pressures and temperatures. A double-eccentric (double-offset) butterfly valve has its shaft positioned with two offsets from the disc and seat centreline. This means the disc lifts cleanly away from the seat almost immediately on opening, and seats with a cam-like action on closing – resulting in virtually no rubbing wear. This gives significantly longer service life, better suitability for higher pressures and temperatures, and a tight metal-to-metal seal. FERGO's Double-eccentric Butterfly Valves are the right choice for demanding process engineering, power generation, shipbuilding, and applications where long-term tightness is critical.
Both allow the valve to be operated automatically without manual intervention, but they differ in speed, power source, and ideal use case:
- Electric Butterfly Valves – Powered by mains electricity (24V, 230V, 240V). They offer precise positioning, easy integration into PLC and building management systems via control signals (0–10V, 4–20mA), and clear position feedback. The ideal choice for building automation, Industry 4.0 environments, and applications requiring modulating control. See Electric Butterfly Valves.
- Pneumatic Butterfly Valves – Powered by compressed air. They are extremely fast-acting and powerful, making them the preferred choice for quick-cycling processes, emergency shut-down systems, and hazardous (ATEX/Ex) areas where electrical equipment is restricted. Available in single-acting (spring-return, fail-safe) and double-acting variants. See Pneumatic Butterfly Valves.
FERGO butterfly valves cover a very wide range of nominal sizes from DN25 (1") up to DN1200 (48"). Available pressure ratings (PN classes) include PN6, PN10, PN16, and ANSI/ASME Class 150, making them compatible with both DIN and imperial flange standards. Sizes and pressure ratings available depend on the specific subcategory – for example, standard Fergo Butterfly Valves and Pneumatic Butterfly Valves cover the full DN25–DN1200 range, while DVGW-certified valves are available from DN25 to DN300. Use the product configurator on this page to filter by nominal width, connection standard, and pressure class to find your exact match.
Ductile iron (GGG40) with epoxy coating is the standard body material for most industrial butterfly valves – it is highly robust, cost-effective, and suitable for the vast majority of water, air, and neutral media applications. You should upgrade to a Stainless Steel Butterfly Valve when your application involves one or more of the following:
- Corrosive or aggressive process media that would attack iron over time
- Food, beverage, or pharmaceutical processes where hygiene standards and material compliance are required
- Outdoor or marine environments where the valve body is exposed to corrosive atmospheres or seawater
- High-purity applications where iron contamination of the medium is not acceptable
