Overpressure protection devices
Overload protection devices


Application of water siphons

Water siphons in U-shape are designed for horizontal pressure tapping, in circular design for vertical pressure tapping.
Condensate forms in the siphon, which prevents the hot medium from entering the measuring device. We recommend filling a cooling sealing liquid (e.g. water) into the siphon before commissioning the pressure line.

Application of overpressure protection devices

Adjustable overpressure protection devices serve as protection against occurring overpressures that exceed the measuring range of the pressure gauges.
When the set pressure is reached, the valve closes automatically and blocks the flow to the pressure gauge. After the pressure drops by approx. 25% below the closing pressure, the valve opens and releases the flow again.


Rubber protection caps
for pressure gauges (DS 63, DS 80 and DS 100, others on request)
For pressure gauges with radial and axial pressure connection



Thread adapter
Reducing screw fitting
Made of brass or stainless steel
With sealing pin (for profile sealing rings) or self-sealing

Dichtungen und Dichtscheiben

Seals + sealing washers
Profiled sealing rings made of copper or aluminum, for internal centering by centering pins.
Gauge flat seals to DIN 16258 made of PTFE, nickel, copper or NP uni.


KST Cooling section
Stainless steel cooling element for pressure gauges.
Max. 400 bar. Max. 250°C.


Application of rubber protection caps

Rubber protective caps are simply slipped onto the pressure gauge before mounting.

They protect the pressure gauge from impacts, for example, and extend its service life.

Application of KST cooling device

The cooling element causes - due to circulation of the ambient air and heat radiation - a cooling and lower heating of the pressure medium in and at the pressure gauge.


Push button tap
with DVGW approval.



Capillary reactors
Capillary lines
Material: brass/copper or stainless steel


Application of push button taps

The push button valve is designed with an automatic closing device and pressure relief on the gauge side, for use in plant engineering and operating pressures up to 4 bar.

The pressure gauge is only pressurized when the pushbutton is actuated.

Application of capillarys

Capillary reactors are used for effective damping/choking of pressure peaks.

Capillary lines are used for effective cooling at very high medium temperatures.
