P1DPiston rod lockingP1D-LP1D-DP1D cylinder with piston rod lockingThe P1D cylinder is available in a version with piston rodlocking, allowing the piston rod to be locked in any position.The lock unit, of the air/spring actuated type, is integrated inthe front end piece of the cylinder. With no signal pressure, thefull force of the lock is applied to the piston rod, and the lockis released at 4 bar signal pressure. Lock units are availablefor P1D Standard (P1D-L) and P1D Clean (P1D-D) in bores32-125 mm. P1D Standard can be ordered with a lock unitand a built-in valve (P1D-4). Of course, the entire range of P1Daccessories can also be used for the locking cylinder, whichcan be ordered with factory fitted accessories, sensors andvalves. However, the lock unit increases the overall length ofthe cylinder. Compare the dimensional diagrams on pages 26and 51. The overall dimensions specified in the catalogue forbuilt-in cylinder fittings, pages 56 - 64, are only correct for P1Dstandard versions without lock unit.Clean and compact designThe front end piece and lock unit form an integrated block,keeping the length of the structure short. The design is easyto clean, sealed and waterproof. The exhaust air from thelock unit can be removed by replacing the filter unit with aconnector and hose. This is an advantage in terms of cleaningor when environmental factors are important.Locking and braking.The static locking force corresponds to 7 bar pressure. Undercertain circumstances, the lock can also be used as a brakefor positioning or similar applications. The maximum values setout in the graph on page 49 must not be exceeded.Function on pressure lossThe piston rod lock can be used in all material handlingsystems where controlled fastening or positioning is required.The piston rod lock is also suitable for use as a pressure-lossbrake for cylinders with suspended loads, for example. Seelock forces.The signal air to the lock unit can be connected directly tothe air system or to the supply air for the valve controlling thecylinder in question. For controlled on/off operation of the lockunit, a separate valve, with large exhaust flow capacity, isused.06.0548www.parker.com/euro_pneumatic
