Armaturen Arndt stands for quality and precision in the manufacture of high-pressure and small valves as well as manometers and globe valves. With decades of experience, the company offers solutions for liquids, gases and steam – ideal for applications in the chemical, energy, mechanical engineering and process industries.
For extreme operating conditions up to 640 bar and temperatures up to +540 °C. Materials: steel, stainless steel.
For precise control in pressure measurement arrangements.
Materials: steel, stainless steel, brass.
For safe pressure measurements in liquid and gas pipes.
Operating pressure up to 400 bar, temperature up to +200 °C.
Material selection according to pressure and temperature requirements, up to 640 bar and +540 °C.
High-pressure valves up to 640 bar for test rigs and hydraulic circuits.
Stainless steel versions for aggressive media, temperatures up to +540 °C.
Pressure gauge shut-off valves up to 400 bar and +200 °C on steam and feedwater lines.
Needle valves for sensitive throttling in measuring and secondary lines.
Stainless steel versions for cleaning and process circuits.
Needle valves damp pressure surges upstream of transmitters and pressure measuring assemblies.
We trade in valves from Armaturen Arndt and supply from the manufacturer range. The series described below are the ones we supply most often – we can source the complete range, including series not listed here.
Both series are small-bore valves with a female thread at both ends, for measuring, test and high-pressure lines. The difference lies in the pressure range and in the choice of materials.
| Series | Connection | Pressure ratings | Materials | Temperature |
| Needle valve Fig 110 | female thread G 1/8 to G 2 | up to 400 bar from G 1/8 to G 1/2, 200 bar at G 3/4 and G 1, above that 160 and 120 bar respectively | steel or stainless steel 1.4571 | −20 °C to +350 °C in steel, up to +250 °C in 1.4571 |
| Small-bore valve Fig 108 | BSPP female thread G 1/4 to G 1 | up to 640 bar from G 1/4 to G 1/2, 320 bar at G 3/4 and G 1 | 1.0460, 1.4571, 1.4104 and 1.7335 | up to +540 °C in 1.7335, up to +400 °C in 1.4104 and 1.0460, up to +250 °C in 1.4571 |
The selection starts with the material, not the pressure: on the Fig 108 the material determines the permissible temperature – 1.7335 up to +540 °C, whereas stainless steel 1.4571 only reaches +250 °C. Anyone who needs both high pressure and high temperature cannot avoid the material question.
For direct level monitoring in vessels and pipework we supply glass tube indicators, valve-type liquid level indicators and intermediate brackets. Nominal sizes DN 15, DN 20 and DN 25 with a threaded connection G ½”, ¾” and 1″ or with a flange. Materials are brass or stainless steel 1.4571. They are used in vessel construction and in the chemical, energy and food industries.
Our standard is the unchanged series version from the Armaturen Arndt range. In addition we can offer for Armaturen Arndt products:
Armaturen Arndt specializes in high-pressure valves, needle valves and manometers shut-off valves for industrial applications. The products are suitable for liquids, gases and steam and cover pressure ranges up to 640 bar and temperatures up to +540 °C. [F…datasheet | PDF]
Armaturen Arndt valves are made of steel, stainless steel or brass to ensure high resistance to pressure, temperature and aggressive media.
Yes, Armaturen Arndt offers individual adaptations for special applications, such as special connections, materials or designs for extreme operating conditions.
The valves are suitable for the chemical, energy, mechanical engineering and process industries as well as for applications in pressure measurement arrangements and high-pressure systems.
Automated globe valves can be supplied pre-configured by our partners. We do not retrofit automation to standard valves.
