- Shut-off device for pressure measuring instruments, for measurement of liquids, gases and vapours
Special Features
- Version per DIN 16261, DIN 16262 and DIN 16263
- Nominal pressures to 25 bar
- Operating temperature up to 50 °C
Description
Stopcocks provide the opportunity to either vent the connected pressure gauge according to the position of the handle (venting position), i.e. put it into a pressure-free state, or to vent the pressure measuring instrument under pressure (operating position) or to let the pressure medium escape (blow position). For pressures higher than those in the data sheet, shut-off valves must be used. Test connection version.
Stopcocks with test connection are intended for the simultaneous connection of operating pressure measuring instruments and test connection pressure gauges to the pressure pipeline. With this version, the third route, which leads to the outside at the standard version, is used asconnection for a test connection pressure gauge. A fourth position of the handle enables the simultaneous connection of the operating and the test connection pressure measuring instruments to the pressure pipeline.

| Adaptors |
Product Description
Applications
For the installation of pressure measuring instruments, gauge cocks, shut-off valves, pressure gauge syphons, snubbers and other component accessories.
Types of adapters
Male-female adapters are used where the size of the male thread is different from the female thread in the parts to be connected.
Female-female adapters are used where both components to be connected have male threads.
Male-male adapters are used where both components to be connected have female threads.
Self-sealing nipples (SS) are used to adapt a smaller size threaded connection to a larger one (e.g. G ¼ auf G ½). Due to their design, the nipples are self-sealing (i.e. the taper turned into the nipple presses into the bore of the pressure measuring instrument’s pressure channel connection. To protect against inadvertent release of the two threaded parts, they are secured with a special adhesive.
LH-RH unions per DIN 16283 have a right-hand thread on one side, and a left-hand thread on the other, which allow the component to be sealed and orientated into any direction required.
Union nuts with nipple per DIN 16284, enable mounting without having to change the orientation of the parts to be connected against each other. Solderless compression fitting with ferrule are used to connect pressure measuring instruments or fittings with pipelines from copper, steel and stainless steel. Particularly useful mounting, no solder or weld points. A sealing washer is included in the delivery.
Flange set with lens-type sealing ring is used for the assembly of high pressure measuring instruments (up to 4000 bar). Through the two threaded flanges, which are clamped by four bolts, the pressure measuring instrument can be positioned in any orientation required.
Weld-on adapters with male thread they are used with left-handed threads for connection with LH-RH union, and with right-handed threads (per EN 837-1) they are mainly found with direct pressure port entries.
Rotatable gauge adapters (swivel adapters) enable the orientation of pressure measuring instruments through a 360 ° range.

| Chemical Diaphragm Seal |
Product Description
Applications
• For aggressive, hot, corrosive, environmentally hazardous or toxic media
• Process industry
Special Features
• Process connection with thread to provide for direct threaded connection
• Version with internal diaphragm, diaphragm seal parts screwed together
• Large selection of process connections and materials
Description
Diaphragm seals are used to protect the pressure measuring instrument from aggressive, adhesive, crystallising, corrosive, environmentally hazardous or toxic media.
A diaphragm made of the appropriate material provides for the separation from the medium to be measured. Thus even the most difficult measuring requirements can be met by combining measuring instruments with diaphragm seals.
A fluid inside the system, which can be chosen to suit the particular application, hydraulically transmits the pressure to the measuring instrument.
Almost limitless application possibilities exist due to the large number of available variants, such as diaphragm seal designs or materials. The type of process connection (flange, threaded and sterile connection) and the basic method of manufacture are important design differentiation criteria.
Due to its design, diaphragm seal with threaded connection can be used universally. A replacement of the lower body is possible (e.g. when changing the process connection) without having to carry out modifications on the diaphragm seal system.
Assembly of the diaphragm seal and measuring instrument is made via a direct assembly as standard or optionally via a cooling element or a flexible capillary.
For the material selection we offer a variety of solutions, in which the upper body, the diaphragm and the lower body can be made of identical or different materials. The diaphragm and the lower body can also be offered coated or covered with foils.
diaphragm seal is particularly well suited for aggressive or hot media. This instrument is mainly geared to applications in the process industry.

| Snubber |
Product Description
Applications
- Snubbers for pressure measuring instruments are intended to suppress the effect of pressure surges and pressure pulses of the medium
- Stainless steel version for aggressive media, even in aggressive ambience
- Process industry: Machine building, general plant construction, chemical/petrochemical, power plants, mining, on- and offshore and environmental technology
Special Features
- Max. temperature 120 °C
- Nominal pressures up to 400 bar
Description
The snubber is adjustable (modification of the crosssectional flow) and can thus be adapted individually to the respective operating conditions. A readjustment during operation, if required, is possible at any time.
The pulsations and pressure surges in the medium, occurring e.g. in compressors, steam engines, hydraulic presses, tensile testing machines etc., are largely compensated by this snubber. This considerably increases the service life of the pressure measuring instrument and improves the reading accuracy. Standard version

| Syphon |
Product Description
Applications
- Syphons protect pressure measuring instruments from pulsations in the medium and from excessive heating
- Cooling element for fluids, gases and vapours in pressure measurement
- For direct mounting to the pressure connection of the pressure measuring instrument or to the shut-off device (stopcock or valve) mounted underneath
Special Features
- Designs per DIN 16282 or to industrial standards
- Permissible temperatures to 400 °C
- Nominal pressures to 160 bar
- Materials: Steel (1.0039, 1.0345) and stainless steel (1.4571)
Description
Syphons per DIN 16282 U-form, form B, and trumpet form, form D, have a welding connection for the pressure tapping on the process side and a threaded connection on the instrument side.
In the industrial standard versions, threaded connections are also available for the pressure tapping on the process side.
U-form syphons are intended for horizontal pressure tapping; trumpet-form syphons are intended for vertical pressure tapping.
Inside the syphon, condensate is collected, which prevents the ingress of hot media into the measuring instrument. We recommend filling the syphon with a cooling separating liquid before commissioning the pressure line. Options
- Other connection threads
- Special pipe for high temperatures and working pressures
- Material: Monel
- 1.4571 stainless steel, oil and grease-free for oxygen service
- 3.1 / 3.2 material test certificate
- Pipe connectors for pressure measuring instruments, see data sheet

| Thermowell |
Description
Each thermowell is an important component of any temperature measurement point. It is used to separate the process from the surrounding area, thus protecting the environment and operating personnel and keeps aggressive media, high pressures and flow rates from the temperature sensor itself and thereby enables the thermometer to be exchanged during operation.
Based on the almost limitless application possibilities, there are a large number of variants, such as thermowell designs or materials. The type of process connection and the basic method of manufacture are important design differentiation criteria. A basic differentiation can be made between threaded and weld-in thermowells, and those with flange connections. Furthermore, one can differentiate between fabricated and solid-machined thermowells. Fabricated thermowells are constructed from a tube, that is closed at the tip by a welded solid tip. Solid-machined thermowells are manufactured from barstock.
Due to the heavy-duty design, these international design thermowells are the first choice for use the chemical and petrochemical industries and in plant construction.
