When the oil circuit has been filled, the pressure automatically increases: as soon as the pressure set at the sequence valve S is exceeded, the hydraulic intensifier works and increases the hydraulic pressure at port. The sequence valve S have to be setted with pressure valve between 8-9% of the low inlet pressure. The URM4-FL2 and URM4-FL3 hydraulic intensifiers are equipped with an integrated pilot check valve that ensures a fast flow unloading of the high pressure and minimizes any counterpressure caused by inside check valves in line. 12/

4 GV ROTRY JOINTS MULTI-SSGE ROTRY JOINTS WITHOUT LEKGE RECIRCULTION GV series multiple-passage rotary joints are designed to supply rotating or swinging fixtures (work-holders) with pressurized oil. These rotary joints can be coupled when pressurized and must be installed in the centre of rotation. low torque is required for starting the rotating movement. GV multi-passage rotary joints do not require leakage lines as no internal oil leakage occurs. To ensure a long service life of the internal seals, make sure to connect the rotary joint to all hydraulic supply ports. The operating temperature should not exceed 6 C. In addition, we recommend using oil filters with a 1 micron filter mesh. GV rotary joints are made of heat-treated and ground high-quality steel. They are only suited for operation with hydraulic fluids, cooling lubricants must not be used. ROTRY JOINT LICTION (EXMLE) GV series Turntable Fixed table xis of rotation /216

8 Sequence valves LICTION EXMLE C 1 D Sequence valves are used in hydraulic systems that require a pressure-specific priority or sequence of motions. one-directional check valve is provided for the free return flow when operation is inverted. These extremely compact valves can be mounted either with the supplied O-Rings or in-line using the S ports directly on the clamping equipment. Material: Valve/cartridge body: Free machining steel, blued. Internal parts: High-grade steel, tempered and ground. Valve body surface: Zinc-plated XX bar 3 2 pplication example: 1) Cylinder no. 1 pushes the workpiece against the D stop. 2) The pressure increases up to XX bar and opens the sequence valve. 3) Cylinders no. 2 and no. 3 push the workpiece against the and C stops. 4) The pressure uniformly rises in all cylinders as the sequence valve is completely open.

Ø22 General instructions This valve is used to provide a reduced constant outlet pressure at the port as compared to the higher inlet pressure at the port. If pressure increases are likely to occur at the port, a pressure relief valve must be installed at this port. Mounting instructions: efore tightening the valve, unscrew the counter nut (F=3 Z) completely. Tighten the valve body (F=24 Y) with a torque of 7 Nm. Then tighten the counter nut (F=3 Z) with a torque of 6 Nm. roceed in reverse order for demounting. ossible outlet pressure drop (bar) Valve-controlled outlet pressure (bar) DJUSTMENT SEQUENCE The pressure reducing valves of cartridge type VR are designed as two way valves without drainage. s soon as the set pressure is reached, the appropriate cone moves in closing position and with increasing pressure, stable closing is ensured as long as the pressure upstream from the valve is not released. To adjust the set pressure, proceed as follows: 1) Loosen the R counter nut in order to ensure free access to the R1 adjusting screw. 2) ressurize the valve and check the set pressure downstream from the valve. 3) Release the pressure. 4) Turn the R1 adjusting screw clockwise or anticlockwise, i.e. turn it clockwise to reduce the set pressure and vice versa. ) ressurize the valve and check again the set pressure. Repeat the above steps until the desired pressure value is reached and tighten the R counter nut. NOTE HYDROLOCK checks all products to 1% before shipment. If requested during order placement, HYDROLOCK will deliver the valve with the pressure being set to the specified value /216

12 C3F RESSURE MONITORING CYLINDER MX. OERTING RESSURE = 3R Y Ø6 Z 3 STROKE 99. M3x The C3F pressure monitoring cylinder has been developed to check the clamping pressure in a remote fixture. s soon as the clamping pressure is reached, the external bolt is extended by 3 mm from the cylinder head and remains in this position as long as the operating pressure required for the fixture is maintained. If the clamping pressure decreases, the rod is retracted again into its initial position. Thanks to the easy adjustment of the operating pressure by an adjusting screw at the cylinder and the availability of different pressure ranges, the CG3 stands out for unparalleled versatility. 2 MIN Ø M3x1. Ø18 MX 4 MX pplication: When the fixture is separated from the hydraulic pressure generator, the use of a hydraulic accumulator is not always sufficient to keep the operating pressure at a level that ensures safe and reliable machining. Substantial oil leakage may reduce the clamping pressure exerted on the workpiece and cause serious damage to the equipment. y using the C3F pressure monitoring cylinder, the operating pressure can be checked immediately before the machining process. If the required pressure level is not reached, the machining process is not enabled and the machine changes into emergency status. Ø Included in the scope of supply: Sealing ring Ø22XØ28X1.

With the CV1 valve protection cartridge the final user can perform clamping operations without any workpiece being mounted in the fixture for a functional check or for cleaning purposes. In this case, there is no risk of damage to the VCS clamp arm position control valve caused by excess stroke Installing the valve protection cartridge: The valve protection cartridge is factorymounted to HYDROLOCK cylinders when ordered as an option. However, retrofitting can also easily be carried out by the end user on the basis of corresponding mounting instructions. simple M12x1 threaded seat is required on the clamp arm plate for mounting the valve protection cartridge for clamp position control valves. Ø6 DJUSTMENT OF THE VLVE ROTECTION CRTRIDGE: To adjust the valve protection cartridge for clamp arm position control valves, proceed as described in the instructions 1 to 4 for the adjustment of the clamp arm position control valve. Use the mm hexagon socket provided at the threaded cartridge end for this purpose. Upon completion of the adjustment, the pressure switch will indicate that the compressed air circuit is closed and enables the machine cycle start. The bolt of the valve protection can compensate an excess stroke of up to 1 mm and re-establish the starting conditions as soon as the cylinder has reached the unclamping position. Make sure that no stroke over 1 mm is performed during clamping operations without workpiece. We recommend mounting the swing clamp cylinders such as to ensure that the clamp arm in clamping position is close to the lower limit stop of the piston. In this case, the workpiece is properly and reliably clamped and perfect operation of the valve protection cartridge is guaranteed /216
