High pressure hoses ND4 (figure 1)
in variable lengths and connectors
The freely selectable hose lengths should be generously dimensioned, in order to avoid kinking, abrasion marks, torsion, tensile and compressive stress and unacceptable bending radii. Protect against hot swarf.
Burst pressure 2000 bar, smallest bending radius 100 mm.
*Further information see DIN 20066

Connectors: see figure 2

Quick-disconnect coupling G 1/4 (figure 3)
The quick-disconnect coupling is a coupling of sturdy design which locks automatically after uncoupling. Connection and disconnection is made in the unpressurised condition. The displacement of the sleeve to the corresponding coupling or uncoupling direction enables an easy one-hand operation.

Pressure relief valve (figure 8)
Safety valve to prevent exceeding the maximum admissible pressure and for limiting operating pressures.


Pressure control valve (figure 9)
Pressure control valve for keeping the lower output pressure in the secondary circuit constant without affecting the higher pressure in the primary circuit.
