Parker Positioning Cylinder

Parker Positioning Cylinder

We offer a comprehensive range of Parker Position Cylinders that are excellent means of providing multipurpose and affordable monitoring piston position in hydraulic cylinders. Equipped with a switching signal ( Position Switches ) it can be applied to regulate used to control or structure operations which are similar to precise points in a manufacturing process, as permitted by the location of the cylinder's piston. The Parker switch is an unobtrusive external device, which finds application on steel structured cylinders working at top pressure. These switches are customized to the cylinder and must be indicated at the time of order.
