Special valves- we offer a wide range!

Our delivery program includes:

Filler -/ filler and breather valves
Throttle valves
Ventilation throttle valves
Pressure gauges
Sight glass
Angle seat strainer
Float valves
Water jet pumps

Butterfly throttle valves

Butterfly throttle valves are non- thight - sealing valves. They are used for the safe transport of big volumes of gaseous media.
We manufacture flange connection dimensions and installation lengths according to customer requirements. You can also choose between manual, pneumatic or electric actuators. We will be glad to advise you.

available nominal sizes: DN 50 - DN 2000
body materials:
PVC, PP, PPs, PVDF, PVC-GFK, PP-GFK,
sealing materials: EPDM, FKM

Gauge guard

Gauge guards are used for pressure measurement of neutral and aggressive media. The pressure sensor is hermetically separated from the medium by a PTFE-coated diaphragm integrated in the gauge guard. The FRANK gauge guard is low-maintenance and achieves excellent measuring accuracies.

measuring range: 0 bar - 10 bar
body materials: PVC, PP, PVDF
diaphragm material: PTFE

Inspection glass

Pipe inspection glasses are used for visual inspection of fillings and flows in pipelines.
FRANK inspection glasses are free of dead spaces, have a barrier-free passage and offer a particularly high level of safety, even when transporting chemicals, thanks to the borosilicate glass used and the double seal.

available nominal sizes: DN 15 - DN 150
larger nominal diameters on request
body materials: PVC, PP, PVDF
seal materials: EPDM, FKM

Y-strainer

Y-strainers in pipe systems are needed to protect sensitive fittings and pumps from contamination and thus from damage. We supply different mesh sizes for a wide range of applications.

available nominal sizes: DN 15 - DN 250
larger nominal widths on request
housing materials:
PVC-transparent, PVC, PP, PVDF
sealing materials: EPDM, FKM

Use of special valves

Filler and breather valves are mainly used to vent containers, e.g. to prevent underpressure.

Throttle valves are used in pipelines where the volume flow (liquids and gases) is to be throttled.

Float valves are used for automatic supply control of tanks and vessels without additional auxiliary power. They are used to keep filling levels at a constant level.

Water jet vacuum pumps are mainly used for pumping and mixing chemical media, metering acids and alkalis, and lifting liquids.
