Hydro-electric pressure switches in piston design convert the pressure in hydraulic systems into electrical signals. The switching point can be continuously adjusted and locked by means of an adjusting knob within different adjusting ranges.

ROEMHELD F9.300 Cutting Ring Unions as per DIN 2353, with Connecting Inserts

• Fittings: ø6 - ø16 mm, G1/8 - G 1/2
• Hydraulic pipes: ø8 - ø15 mm
• Hydraulic oil: HLP22 - 46, Oemeta HF-Du
• Pressure gauges: 0-40 - 600 bar
• Plug-in connectors: ND5
• Maximum operating pressure 250 - 500 bar

ROEMHELD F 9.425 Coupling Units for manual operation, for single and double acting cylinders

• Maximum operating pressure 400/500 bar
• Connection: coupling nipple
• Port - pressure generator: G 1/4

This coupling unit is used if the clamping fixture is manually separated from the pressure generator, e.g. in flexible manufacturing systems or when using one pressure generator only for several clamping fixtures. It can be supplied with two different accumulators: Size 1 for clamping fixtures with a big oil volume. Size 2 for clamping fixtures with a small oil volume.

ROEMHELD F 9.290 Rotary Valve Couplings

• ND 5
• Max. operating pressure 500 bar
• Loading and unloading in one station
• Loading and unloading in two stations
• Commonly or separately controlled
• Number of stations 5 to 10

ROEMHELD D8.817 Two-Stage Hydraulic Pump with automatic change-over from low stage 60 bar to high stage 500 bar

• Displacement per stroke up to 60 bar: 12 cm³
• Displacement per stroke up to 500 bar: 2.4 cm³
• Oil volume: 400 - 2000 cm³
• Usable oil volume: 200 - 1800 cm³
• Operating force: 216/360 N
• Hydraulic connection: G 1/4

ROEMHELD D8.753 Single and Double acting Hydraulic Intensifiers

• Intensification ratio 1:4
• Maximum operating pressure 500/125 bar
• Single and double acting
• Intensification ration: 1:4
• Intensification volume: 21 cm³
• Maximum flow rate: 8 l/min (low-pressure side)
• Maximum operating pressure 125 - 130 bar (low-pressure side)

This ROEMHELD Hydraulic Intensifier convert a hydraulic pressure on the primary side (input) into a higher pressure on the secondary side (output). This enables the use of the comparatively low pressure of machine tool hydraulics to pressurise a hydraulic cylinder with quadruple pressure.

ROEMHELD D8.602 Hydro-pneumatic pump units for single and double acting cylinders

• Flow rate: 0.85 l/min
• Minimum operating pressure: 50 bar
