Gate valve - Wedge gate valve

We have a wide range of gate valves for many different applications. Whether you need wedge gate valves in GG25, GGG40 or stainless steel, we have them in stock up to DN300. Our wedge gate valves are equipped with both a metal seal and a rubberised wedge, either NBR or EPDM. Our valves are fitted with a handwheel as standard. However, it is also possible to equip individual series with pneumatic or electric actuators and quick-closing levers.

Fergo Armaturen GmbH has a wide range of different gate valves. The gate valves differ mainly in the connection type, the overall length, the body material, the maximum pressure relief, the wedge seal and the available certificates (TA Luft, DVGW drinking water).

FAQ: Wedge gate valve, oval wedge gate valve and flat wedge gate valve

What are wedge gate valves, wedge flat gate valves and wedge oval gate valves?

Wedge gate valves, wedge flat gate valves and wedge oval gate valves are types of industrial valves that are used to control the flow of liquids and gases in pipelines. They are characterised by their wedge-shaped gate valve blade, which moves perpendicular to the direction of flow to open or close the valve.

Which housing materials are used for gate valves?

The most common housing materials are:

Stainless steel: Offers high corrosion resistance and strength, ideal for aggressive media and hygienic applications.
Steel: Robust and cost-effective, suitable for general industrial applications.
Ductile iron: Offers good mechanical properties and is economical for various applications.

What sealing materials are available?

The available sealing materials include:

EPDM (ethylene propylene diene rubber): Resistant to water, steam and many chemicals, commonly used in water and wastewater treatment.

NBR (Nitrile Butadiene Rubber): Resistant to oils, greases and hydrocarbons, ideal for the oil and gas industry.

Metallic: High resistance to extreme temperatures and pressures, often used in high temperature and high pressure applications.

Stainless steel: Corrosion-resistant and durable, suitable for hygienic and highly corrosive environments.

What certificates are available for the gate valves?

The most important certificates are

TA Luft: Certification for low-emission fittings, important for environmental protection.

DVGW drinking water: Certification for suitability in the drinking water sector, guarantees hygienic safety.

AD2000: Certification in accordance with German pressure equipment guidelines, important for the safety and reliability of pressure vessels and systems.

AD2000-A4: Special certification for specific requirements for pressure vessels, which fulfils additional safety standards.

In which applications are these gate valves used?

These valves are used in a variety of applications, including

Water and waste water treatment: Due to their resistance to various media and corrosion.

Chemical industry: For the safe handling of aggressive chemicals.

Oil and gas industry: Due to their resistance to oils and hydrocarbons.

Food and beverage industry: Due to their hygienic properties, especially when using stainless steel.

How do I select the right gate valve type for my application?

Choosing the right type of valve depends on several factors:

Wedge gate valve: When you need robust and reliable tightness in general applications.

Wedge flat gate valve: When the installation location is limited and a more compact design is required.

Oval wedge gate valve: If you need a valve for oval pipe cross-sections or special industrial applications with precise flow control.
