The invention relates to a system for connecting rigid pipes and for connecting flexible pipes. The pipes have corresponding outer diameters, with a press jaw having a press contour, with at least one first fitting for press-fitting to a rigid pipe, the at least one first fitting having a first press sleeve with a first outer contour, with at least one second fitting for press-fitting to a flexible pipe, the at least one second fitting having a second press sleeve with a second outer contour, the at least one second fitting having a second press sleeve with a second outer contour has a second press sleeve with a second outer contour, the outer contour of the first press sleeve and the outer contour of the second press sleeve in each case being adapted at least in sections to the press contour of the press jaw of the press jaw and can be pressed by the press jaw and wherein the outer contours of the first press sleeve and of the second press sleeve correspond at least in sections. This system solves the technical problem of simplifying the on-site effort for installing piping systems. In particular, the task is to specify suitable combinations of fittings for rigid and flexible pipes.

A press connection system for non-releasably connecting a fitting to a pipe, with a press jaw, with a press contour formed on the inside of the press jaw. The press contour has a cylindrical press section, with a fitting, with a fitting base body and a press sleeve forming a press chamber. A sealing ring is arranged at the proximal end of the press chamber relative to the fitting base body and a cutting ring is arranged at the distal end of the press chamber relative to the fitting base body. The cutting ring has a central cylindrical section and cutting elements arranged at the distal end and cutting elements arranged at the proximal end. Also a swaged fitting.

The invention relates to a system for producing a sealed connection of a press connector to a workpiece, in particular to a pipe, preferably to a plastic pipe, with a pressing tool for pressing a press connector and with a pressure tool for driving the pressing tool. The pressure tool is arranged to output a hydraulic pressure at a pressure generation point The pressing tool is arranged to receive a hydraulic pressure at a pressing location and to press a press connector accordingly. The pressure tool and the pressing tool are connected via a hydraulic pressure transmission connection, the pressure generation location and the pressing location being remote from each other. A corresponding method for producing a tight connection of a press connector to a workpiece, in particular to a pipe made of a flexible material, preferably a plastic pipe, as well as a press force translator and a press tool are also described.

A pressing tool for pressing fittings to produce pipe connections, with two opposing pressing jaws, each having a pressing section and a lever section, and having a retaining element for swivel connecting the pressing jaws, wherein the pressing sections form a receiving section and wherein pressing the lever sections apart causes the receiving section to close. An actuator spindle, a spindle nut and at least two actuator levers are provided, and each actuator lever is swivel connected at one end to the lever section of a pressing jaw and each actuator lever is swivel connected at another end to the spindle nut. A method for pressing fittings for the production of pipe connections is also disclosed.

A distribution valve with an integrated flowmeter unit, which exhibits a main flow channel, through which a medium can flow in a main flow direction, and a secondary flow channel branching from the latter. The distribution valve includes a distribution valve housing containing a main pipe, a first conduit pipe connection, a second conduit pipe connection and at least one branch lying in between. The main flow channel in the main pipe runs from the first conduit pipe connection to the second conduit pipe connection. The branch empties into a first housing part, which includes an outlet. The outlet of the first housing part empties into a second housing part, which accommodates a flowmeter body and includes an outlet that forms a third conduit pipe connection. The secondary flow channel runs from the at least one branch of the main pipe to the outlet of the second housing part.
