Gate valve for drinking water

The VA200 (short face-to-face length, F4) and VA201 (long face-to-face length, F5) drinking water gate valves are designed for operating pressures up to PN16 (16 bar). Thanks to the high-quality wedge rubber lining, which is made of either EPDM or NBR, these wedge gate valves provide a reliable seal and are particularly robust against pressure fluctuations and chemical influences. Their solid construction makes them suitable not only for drinking water applications but also for use in the wastewater and biogas sectors. The VA200 with the EPDM seal is DVGW-certified and fulfils the highest hygiene and safety standards.

A gate valve for water pipes must be durable and corrosion-resistant, which is why Fergo uses first-class materials. The VA100-MMMNI water pipe gate valve has precision-manufactured brass components that guarantee high mechanical strength and a long service life. It is available in nominal sizes from 1/2 inch to 2 1/2 inch and has a threaded connection in accordance with ISO 228. The body and wedge are made of high-quality CW617N brass, while the seat gasket provides a metallic seal. With a maximum operating pressure of 16 bar (232 psi) and an operating temperature of 0°C to 150°C (without steam), it delivers reliable performance in demanding conditions. The steel handwheel ensures easy and safe operation.

In addition, Fergo offers wedge gate valves and wedge oval gate valves for special applications in water pipes. These valves are characterised by their compact design and high resistance. They ensure optimum flow control and are an ideal choice for drinking water and industrial pipework systems. With their high material quality and sophisticated design, these valves are a reliable solution for long-term and safe operation.

FAQ: Drinking water gate valve

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 gate valve?

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.

Applications and advantages of gate valves

Gate valves are essential components in water supply systems and heating systems. They are used to regulate the flow of liquids in a targeted manner or to interrupt it completely. They are frequently used in drinking water networks and heating circuits in particular due to their reliable operation.

Function and types of gate valves

A gate valve for water pipes differs from other shut-off valves in its design. It consists of a housing, a movable gate valve and a spindle for actuation. The flow opening is opened or closed by lowering or raising the gate valve. In contrast to ball valves or valves, gate valves allow a complete through-opening without significant flow resistance.

Sleeve gate valves are particularly common and are characterised by their ease of installation. They are mainly used in smaller pipework and are often made of brass or cast iron. A brass gate valve is particularly suitable for drinking water pipes due to its corrosion resistance and durability.

Gate valves for drinking water and heating systems

A gate valve for drinking water must fulfil strict hygiene requirements. These components are therefore often DVGW-certified to ensure their suitability for use in drinking water systems. A DVGW gate valve guarantees that no harmful substances get into the water.

Gate valves are also widely used in the heating sector. A gate valve for heating makes it possible to shut off individual heating circuits in order to carry out maintenance work or repairs without putting the entire system out of operation.

Conclusion: Gate valves play a central role in water supply and heating technology. Choosing the right material and design - be it a sleeve gate valve or a special gate valve for drinking water - is crucial for a safe and durable installation.
