Hydraulic Components

ROEMHELD C 2.530 Directional Control Valves ND 6

• Ports: Manifold-mounting with O-ring sealing
• Adm. Flow rate: 80 l/min
• Hydraulic oil: as per DIN 51524
• Nominal voltage: 24 VDC
• Code class: IP 65
• Maximum Operating Pressure: 315 bar

ROEMHELD F9.461 Threaded-body type Coupling Elements without Coupling Stroke

• Maximum operating pressure 200 bar
• Threaded-body type, ND 4
• Nominal diameter: ND 4
• Maximum flow rate: 8 l/min
• Maximum coupling force 4.0
• Positioning tolerance, axial: +0.05 mm
• Positioning tolerance, radial: 2 mm

These automatically closing couplings have a flat surface and do not have protruding elements for sealing. Therefore exact positioning is not required and a radial positioning misalignment of up to 2 mm is admitted. Cleaning of the coupling surfaces is easily possible due to the flat surfaces. Because of the omitted active axial coupling stroke completely new solutions for the coupling motion can be realised.

ROEMHELD C 2.531 Directional Control Valves ND 10

• Ports: Flange with O-ring sealing
• Adm. flow rate: 120 l/min
• Hydraulic oil: as per DIN 51524
• Supply voltage: 24 VDC
• Code class: IP 65
• Maximum Operating Pressure: 315 bar

ROEMHELD F 9.440 Multi-couplings - depressurised coupling or coupling against pressure

• Maximum operating pressure 300 bar
• Complete units with several coupling mechanisms and coupling nipples
• With integrated blast air system
• 2-fold ND 5, 4-fold ND 5, 4-fold ND 8
• Positioning tolerances 0.1 up to 0.5 mm
• Coupling stroke 4.5 mm (ND 5) and 7.4 mm (ND 8)

The multi-coupling is a modification of the threaded coupling elements as per data sheet F 9.430. It comprises of two components, the nipple carrier and the coupling carrier. The advantage of the coupling carrier is the fact that its face is flush in uncoupled condition, thereby it can be easily cleaned by means of the integrated blast air system.
