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. They 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.

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 features precision-manufactured brass components, ensuring 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.
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.
