Quick couplings in coaxial design

For applications with low pressure, coaxial couplings are used to perform special functions. Coaxial couplings are mono couplings carrying media in a coaxial way (pipe in pipe). Furthermore, there are coaxial mono couplings carrying fluidic media and simultaneously high-frequency low voltage electricity (e. g. for spot welding guns, transfer or welding power as well as cooling water) or additionally transmitting signal currents.

13-019

Features

Type:
13-019

Nominal bore:
19 mm

Pressure area:
up to 3 bar

Media:
pressurized air

Material:
stainless steel 1.4404

Applications:
coaxial couplings for cooling of electric lines, e. g. in continuous casting plants (steel industry). The electric plug inside (7- or 12-way) is accessed by pressurized air or protecting gas and thus, protected against overheating. The electric cable is protected when guided into the pressurized air hose. Simultaneously, the penetration of dirt or humidity is prevented. Besides, the pressurized air can be used in the switch cabinets without the necessity to drive additional lines.

Characteristics:
for pressurized air or gases with simultaneous electric contact in coaxial design

 

91006

Characteristics type 91006

Type:
91006

Pressure area:
up to 10 bar

Media:
cooling water

Materials:
steel / brass chemically nickel-plated

Applications:
coaxial couplings – so-called thermodrants – lead the heating water coaxially for the flow and return at the central heating cycle for bus or railway car heating in depots or train stations.
