Gate Valves
Gate valves and globe valves cast steel
Description:
It is possible to install BY-pass valves on the gate valves, which makes the opening and closing of the shut-off / gate valves valves even easier. These equalize the pressure between the wedge sides, so that the shut-off valves / gate valves can be easily opened even at high line pressure.
The gate valves are suitable for temperatures from -25 ° C to 425 ° C. Soft-sealing shut-off valves can not withstand these high temperatures. The metal-sealing, on the other hand, are very robust and can therefore be used in many different ways. Example: gate valve in steel construction (material: 1.0619 / A216 WCB)
Furthermore, the industrial valve can be ordered in steel or stainless steel, with nominal pressure ratings (LBS) between Class 150 and Class 2500. Depending on customer requirements, either a flange connection according to DIN standard and ANSI standard, an internal thread or a welding end can be attached to the connections of the valve. In addition, the seat can be machined with stellite, thus prolonging the service life, since this reduces wear and does not wear out so quickly. In order to avoid certain values, TA – LUFT packings are attached for safety reasons.
The stuffing box packing and the gasket can easily be replaced by these TA-LUFT (Technical instructions for the air purification). This is entirely dependent on your requirements. It is also particularly advantageous that the gate valves can also be installed in explosion protection areas (EX areas), since they are not flammable. The EX protection would have to be checked in advance if a drive is desired.

Gate Valves
Gate Valves are designed for a complete closing or complete opening of a pipe. They are installed in a pipeline as a gate valve and should not be used for regulation. The operation of a gate valve is done by means of a handwheel. For larger Gate Valves, transmissions with gear box and handwheel are installed. As a result, the operation is facilitated. When the handwheel is actuated, the wedge moves up or down through the spindle. This will open or close the gate valve.
Gate Valves are primarily used when near-full passage and minimum pressure loss is required. If Gate Valves are fully open, there are no obstructions that can affect the flow path. This in turn leads to a low pressure loss. The actual operation of the gate valve is made possible by a rotating, rising spindle. The hand wheel turns the spindle, thus driving the wedge down to close or up to open the industrial valve.
Gate Valves can be used for countless liquids and gases, oil, steam. Depending on the version, the Gate Valves supplied by Häger Industriearmaturen are suitable for oil, water, gas, steam, abrasive media and temperatures between -196 degrees up to 600 degrees. Line pressures of up to 400 bar or 4500 LBS can be realized.
Robust and metal seated gate valves
The production of metal seated gate valves dates back to the 18th century, which led to industrialization. The bonnet has a recess in which the wedge is retracted for closing. In addition, sits in the bonnet a sealing ring which additionally seals. In particularly abrasive applications, a so-called build-up welding is applied to the housing seat. This reduces possible corrosion or faster wear of the seat.
Due to the robust design, metal seated gate valves are used especially in the industrial sector, such as hot water lines. Just then metal-sealing gate valves are more advantageous than soft-sealing, since they can only be used up to temperatures of about 200 degrees. Depending on the design, metal-sealed industrial valves can withstand temperatures of up to 800 degrees. However, one disadvantage of the metal-sealing system is that contaminations in the housing seat can make it difficult to close the gate valve. As a result, it can happen that the connected pipe can not be closed or only partially closed. Which can lead to significant problems. Also, then certain leakage rates can not be met.
Gate valves forged steel
Description:
These forged steel gate valves are suitable for very high temperatures since they are metal-sealing. They are very robust and can therefore be used in many different ways.
Furthermore, the industrial valve can be ordered in steel or stainless steel, with nominal pressure ratings (LBS) between Class 800 LBS and Class 2500 LBS in the Pressure Seal version. Depending on customer requirements, either a flange connection according to DIN standard and ANSI standard, an internal thread or a weld end can be attached to the connections of the gate valve.
In addition, the seat can be machined with stellite, thus prolonging the service life, since this reduces wear and does not wear out so quickly.
In order to avoid certain values, TA LUFT packings are attached for safety reasons. The stuffing box packing and the gasket can easily be replaced by these TA-LUFT seals (Technical instructions for the air purification). This is entirely dependent on your requirements. It is also particularly advantageous that the Forged Gate Valves can also be installed in explosion protection areas (EX areas) because they are not flammable. An ATEX Declaration is also available for this purpose. The EX protection would have to be checked in advance if a drive is desired.

Globe Valves
Gate valves and globe valves cast steel
Description:
When the valve is closed, maintenance work on pipelines can be carried out very simply. If you install BY-Pass valves on the valves for an extra charge, opening and closing will become even easier. Actually, the Globe Valve has a minimum input power and is therefore easier to open than the Gate Valve, but the BY-PASS valves take a lot of pressure from the line.
The Globe Valves are available in the same versions as the Gate Valves.
Furthermore, the industrial valve are available in steel or stainless steel, with nominal pressure ratings (LBS) between Class 150 and Class 2500. Depending on the customer’s request, either a flange connection according to DIN standard and ANSI standard, an internal thread or a weld end can be installed at the connections of the valve.
They are suitable for temperatures from -25 ° C to 425 ° C and thus withstand extreme temperature differences. It is available in steel or stainless steel, with nominal pressure ratings (LBS) between 150 LBS and 2500 LBS. This depends on what the pipes are used for and what fluids will be inside. In addition, the seat (seat) can be machined with stellite, thus prolonging the service life, since this reduces wear and does not wear out so quickly.
Depending on customer requirements, either a flange connection according to ANSI standard, an internal thread or a welding end can be attached to the connections.
