Häger GmbH & Co. KG DIN Gate Valves
Essential for every maintenance task: Gate valves are used to fully open or close pipelines. Once the valve is shut, maintenance can be carried out safely and conveniently. Alternative options include ball valves, globe valves, or butterfly valves.
The key characteristics of gate valves
Our heavy-duty gate valves provide full bore flow for quick opening and closing of pipelines, are suitable for water, gas, oil, steam, and media containing solids, and are ideal for high-pressure and high-temperature applications in industrial systems and hazardous (EX) areas. Optional by-pass lines can be integrated as needed.
Easy operation and numerous options
Operation of the gate valve is usually done manually or with a gearbox. Upon request, we also offer electric or pneumatic actuators. For underground installations, a handwheel is not suitable, and for larger nominal sizes, we recommend a gearbox due to high torque requirements.
Various connection options
Gate valves come standard with flange connections for easy installation and removal. Compared to weld ends, flanged connections are more convenient but more prone to leaks—both types are available from us.
Different valve designs
The gate valve’s closure element moves perpendicular to the flow, providing a full bore when open — which reduces pressure loss. Unlike globe valves, gate valves are piggable and can be flowed through in both directions.
Lower leakage rate due to flexible wedge
The wedge-shaped sealing element consists of two plates. These are either welded together by a bridge, or a single wedge is left standing in the middle. The latter design achieves a lower leakage rate than a solid wedge.
External stem thread
With an external stem thread, the packing gland is located below the thread, preventing contact between the thread and the medium. This avoids seizing and allows for immediate visual inspection of the stem.
Wedge gate valve or double disc gate valve
Wedge round gate valves require more space in the pipeline due to their larger design and are inherently longer in length than wedge flat gate valves. While wedge round gate valves are also manufactured for high pressure ratings up to PN 160, the wedge flat gate valve is only suitable for pressure ratings up to PN 16.

The Gate Valve for Every Application Profile
Our gate valves cover a wide range of applications. Depending on the material and design, they are used for water, gas, oil, steam, or other media. For high-pressure situations, we recommend a gate valve with a bypass, as this balances the pressure difference between both sides of the wedge, making operation easier. Additionally, our valves are suitable for high temperatures because certain series feature metal-to-metal sealing. Thanks to their robust design, our gate valves are ideal for industrial plants, such as hot water pipelines. Metal-sealed gate valves are also perfect for large nominal sizes and are well-suited for media with a high solid content. Good to know: Since metal-sealed gate valves do not have their own ignition source, they can be safely used in “EX” protected areas.
A Must-Have: Full Bore, Full Flow
A key advantage of our gate valves is their full bore design. This means the valve does not reduce the nominal diameter of the connected pipes, helping to avoid pressure drops. Especially important for special media such as wastewater, the smooth full bore prevents solids and suspended particles from settling. Additionally, this design allows for pipeline pigging, which reduces maintenance costs and downtime.
Features of Gate Valves
Our robust gate valves provide full bore flow for quick opening and closing of pipelines. They are suitable for water, gas, oil, steam, and media containing solids. Ideal for high-pressure and high-temperature applications in industrial plants as well as in EX zones. They can also be equipped with an optional bypass for easier operation when needed.
Modular Design – Unlimited Combination Options
Although we can only speculate, it’s safe to say that no other valve is available in as many variants as the gate valve. Thanks to the modular design of its components, we provide a product that always meets your requirements. Of course, we also offer custom solutions if your application is not fully covered by our broad portfolio.
Examples:
If your medium contains a high amount of solids causing faster wear on the gate valve seat, we can upgrade the seat with Stellite armor for a small extra charge. This significantly extends the valve’s lifespan. For seawater or highly corrosive environments, we offer special materials such as Duplex (1.4462) or Super Duplex.
Depending on the application, the packing gland can be replaced with a “TA-LUFT” packing to ensure compliance with air purity regulations.
Material Options Available Upon Request
Different pipeline requirements call for different materials. We offer our valves in a wide range of materials to meet these needs. For temperatures between -29°C and 429°C, steels such as C22.8, A105, 1.0460, P250GH, A216 WCB, A216 WCC, 1.0619, and GS-C25 are suitable. For even more extreme conditions, stainless steel materials like 1.4301, 1.4401, 1.4404, 1.4408, 1.4541, 1.4571, and CF8M can handle temperatures ranging from -196°C up to over 600°C.
Coatings for Every Application
Depending on the application, coating is essential. In certain environments, it is absolutely necessary to protect the valve against corrosion. For example, a gate valve installed near the sea or in sandy areas may face faster material erosion due to solid particles like sand. That’s why we are happy to advise you on coatings and tailor the perfect solution package for your needs.
Gate Valve or Globe Valve – Here You’ll Find the Differences
Gate valves have a significantly lower pressure loss compared to globe valves. Depending on customer requirements, this can be an advantage or a disadvantage. Additionally, the flow direction is always fixed for globe valves, whereas gate valves can be operated from both sides. Due to the valve’s design, globe valves cannot provide a full bore. The constriction in the body causes the higher pressure loss. However, a clear advantage of globe valves is their ability to regulate the medium by redirecting the flow. With an additional control plug installed on the globe valve’s plug, even finer regulation is possible.

Industrial valves are considered to have the same hazard potential as pressure vessels. Therefore, when planning, installing, operating, and maintaining valves, not only the operating instructions but also the relevant accident prevention regulations, applicable standards, and technical literature must be taken into account. All activities required for the use of valves must be carried out exclusively by trained specialists! During valve installation, utmost cleanliness must be ensured.
During commissioning, the tightness of the gland packing and the bonnet flange connection, as well as the pipe connection flanges, must be checked. If necessary, the bolted connections should be retightened. Persistent leakage can cause erosion of sealing surfaces, leading to leaks. The tightness should be rechecked after some time, as seals and bolt materials—especially at high temperatures—may settle during the initial period of operation.
The gland packing spindle seal and bonnet gasket are subject to wear over time. Depending on usage, gland packings need to be tightened, repacked, or replaced periodically. Before loosening the gland, the valve must be depressurized.
Yes! The gate valve must always be either fully open or fully closed. A gate valve is not suitable for throttling; otherwise, cavitation may occur.
